Developpement Larvaire Du Serpulien Cavernicole Marifugia Cavatica Absolon Et Hrabe (Polychaeta, Sedentaria), Janez Matjašič, Boris Sket
International Journal of Speleology
Among material coming from Hercegovina some living trochoporae of the cave Serpulid Marifugia cavatica have been found. In the laboratory of the Biology Institute of Ljubljana the further development passing stages of metatrochophore and nectochaeta have been observed. The constitution of the trochophore is typical. The nectochaeta possesses three metamera and each of these has only one pair of setae. The nectochaeta once it gets attached to the bottom the neck and beginning of tentacles are beginning to develop. The tube, three pairs of simple tentacles and the opercula are formed in further stages. For the period in which the …
A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger
A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger
International Journal of Speleology
Four pools were observed in Banners Corner Cave, Russell County, Virginia, over a 28 month period from November 1961 to February 1964. Three of these pools were visibly polluted with sewage which had seeped into the cave from septic tanks located on the hill above. All four of these pools, at one time or another during the study, contained large populations of planarians, Phagocata subterranea Hyman and isopods, Asellus recurvatus Steeves. Physicochemical and microbiological analyses of the pool waters indicated that oxygen tension is a low as 2.8 mg./l. in one pool and that coliforms and other forms of bacteria …
The Geographical Distribution Of Australian Cave-Dwelling Chiroptera, E. Hamilton-Smith
The Geographical Distribution Of Australian Cave-Dwelling Chiroptera, E. Hamilton-Smith
International Journal of Speleology
Of the 56 species of bats currently recorded from Australia, 22 are known to occur in caves. The geographical distribution of each of these species is detailed, and from this data, the species are divided into four groups according to their pattern of distribution. Group I comprises those species found only North of 18°S latitude, all of which either also occur in New Guinea or are closely related to New Guinea species. Group II, including both endemic Australian genera, occurs over that area North of 28°S latitude. This area largely comprises desert or semi-desert terrain, with its characteristics of low …

Contribution À L'Etude De Bathynella D'Europe: Bathynella Natans Vejdovsky, Un Dilemme À Résoudre, Eugène Serban
International Journal of Speleology
After a minute study of the structure of the 8th male pereiopod in some Bathynella populations from Romania and England, the structure differences which were found allowed to identify two well individualized kinds of pereiopods; they were named type natans and type stammeri. Taking into account the striking differences between these two types, B. stammeri (Jakobi), which since 1954 is considered to be a subspecies of the natans species, was separated out of the species B. natans sensu Jakobi (1954). The populations understudied were collected in England and Romania, their minute study being the object of an other note, …
Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu
Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu
International Journal of Speleology
Experiments were designed to test the ability of the aphotic speleoenvironment to support algal growth. The first series contained gelatin cultures of Scenedesmus placed in the cave at different localities in order to establish whether or not the microhabitats have any particular effect on the multiplication of the algae. No differences were found in the cultures after a three month incubation period in the cave, which could be traced to influences of microenvironmental conditions. Chlorella cultures in sterile Knop’s solution showed measurable growth in the cave whereas if the cultures were installed into sterilized cave water or were shielded by …

Les Crustacés Du Réservoir De La Fontaine Des Suisses À Dijon, Bernard Dussart, François Graf, Roger Husson
International Journal of Speleology
Inventory of the Crustaceans collected in the basin of the Fonatine des Suisses at Dijon. The Copepoda are represented by 5 species: Macrocyclops albidits, Eucyclops serrulatus in two slightly different forms, Eucyclops serrulatus var. mihi, Acanthocyclops venustus, Acanthocyclops vernalis and Acanthocyclops robustus. The coexistence of these two last forms in this very tiny environment makes it probable that we have here to do with two distinct species. A determination key is given for the Genus Acanthocyclops. Amphipoda are represented by Niphargus virei and especially Niphargus kochianus kochianus of which more than 100 samples have been …
Hommage À La Mémoire De René Jeannel, Constantin Motas
Hommage À La Mémoire De René Jeannel, Constantin Motas
International Journal of Speleology
In this paper the author evokes the principal stages of activity in the life of the great French speleologist, René Jeannel. He records the admiration and respect attributed to Jeannel in the field of entomology. Emphasis is given to the work of Jeannel at Cluj, Romania, carried on with E. G. Racovitza and P. A. Chappuis. A summary is made of Jeannel’s many travels. The significant conclusions of these are presented as well as an insight into the character of this prominent French naturalist.
Algae From The Cave Of Mátyás Mount, Budapest, Hungary, P. Palik
Algae From The Cave Of Mátyás Mount, Budapest, Hungary, P. Palik
International Journal of Speleology
Seven collections containing scrapings of speleoclay or samples from the cave waters were received from L. Hajdu and were cultured in light in a modified Knop’s solution. The cultures yielded 21 different algal taxa, of which five species belong to the Cyanophyta four to the Bacillariophycaea class of the Chrysophyta and twelve to the Chlorophyta. From the species distribution, the cave shows a similarity to the nearby cave of Pàlvolgy, namely both of them contained more than 50 per cent Chlorophyta. Among the Cyanophyta the occurrence of Baradlaia speluncaecola Palik is noteworthy. This species seems to be a true troglobitic …

Materialien Über Die Ökologie Und Biologie Von Sphaeromides Bureschi Strouhal, Angel Angelov
International Journal of Speleology
The acquatic cave Isopod Sphaeromides bureschi Strouhal was discovered by I. Buresch in the underground water of two caves in western Stara-Planina. In this paper the author describes a new station, a spring, in the same region and then exposes the results of ecological and biological observations on this species (biotope, temperature, sex-ratio, feeding regime, locomotion).
Three New Species Of Cymbella From Mammoth Cave, Kentucky, Sam L. Van Landingham
Three New Species Of Cymbella From Mammoth Cave, Kentucky, Sam L. Van Landingham
International Journal of Speleology
During an investigation of the diatom flora of Mammoth Cave, Kentucky three Cymbella species were noted which could not be identified with any yet described forms. This paper contains a taxonomic description of the three new species: Cymbella clausii, Cymbella gerloffii, Cymbella hohnii. A common feature of all three species is the rather broad central area which may have been the result of a special adaptation to the cave environment.
Contribution À La Systématique Des Stenasellinae D'Afrique (Crustacés, Asellotes), Guy Magniez
Contribution À La Systématique Des Stenasellinae D'Afrique (Crustacés, Asellotes), Guy Magniez
International Journal of Speleology
From 1897 to 1962, many species have been described as belonging to the genus Stenasellus Dollfus. Among all these the forms from Central Africa and one of Western Africa are not conform to the generic description of Racovitza 1924 obliging us to institute two new genera, Metastenasellus and Parastenasellus. The archaeic Asellota belong to the genus Stenasellus Dollfus, Johannella Monod, Metastenasellus nov.gen. and Parastenasellus nov. gen. are thus grouped in a sub family of Stenasellinae and the relationship between the different groups has still to be explained.

Nouvelles Contributions À L'Ètude De Bathynella (Bathynella) Natans Vejd. Et Bathynella (Antrobathynella) Stammeri (Jakobi), Eugène Serban
International Journal of Speleology
In an earlier paper the author separated Bathynella stammeri (Jakobi) (formerly considered a subspecies) from B. natans Vejd. sensu Jakobi and showed that this new species justified the erection of a new subgenus (Antrobathynella) of Bathynella. Study of the morphology of the mandible, and the 8th pereiopod of the male and female, and examination of the chaetotaxy of the uropods have revealed new diagnostic characters which permit the unequivocal separation of B. natans and B. stammeri. A diagnosis of both species is given. The present study is the result of examination of numerous specimens from many …

Pelodrilus Bureschi Mich. 1924 (Oligochaeta Haplotaxidae Dans Les Grottes Du Banat (Roumanie), Francise Botea, Lazare Botoşaneanu
International Journal of Speleology
Pelodrilus bureschi Mich., one of two species of limicolous oligochaetes strictly confined to a subterranean environment and previously known from several caves in Bulgaria and Yugoslavia, was recently found in three caves in the Banat Mountains, Romania. Examination of sexually mature worms showed that they are within the range of variability of P. bureschi and that there is no reason to describe a form peculiar to the caves of Banat. Pelodrilus has almost always been found in the mud or clay covering the bottom of pools of variable size, which are filled by periodic flooding of underground water courses. The …
