Cataract Occurrence In Micropogonia Furnieri (Desmarest, 1822) In The Area Between Capes Frio And Torres (23° S And 29° S), Brazil : Investigation Of Causes And Electrophoretic Studies Of Total Proteins Of The Eye Lenses, Anna Emila A. De M. Vazzoler, Van Ngan Phan

Reports

The frequency and distribution of these specimens were analysed and the electrophoretic patterns of soluble eye-lens proteins were determined. This cataract is not of parasitic origin and was rare in specimens from the coastal area. In the lagunar region it occurs mainly in specimens of the River Baguacu from April to November.

Monogenetic Trematodes From The Southern Pacific Ocean Polyopisthocotyleids From The Australian Fishes, The Subfamily Polylabrinae And Microcotylinae, W. A. Dillon, William J. Hargis Jr., Antonio E. Harrises

Reports

This eighth of a series of monogenetic trematodes from the Southern Pacific Ocean discusses two species of Monogenea from Australian waters. Polylabroides mylionis n. sp., from the gills of Mylio butcheri, is described. Neobivagina agonostomi (Sandars, 1945} Dillon and Hargis, 1965, from the gills of Aldrichett~ forsteri, is redescribed; a new locality record is reported for Neobivagina agonostomi.

Reports

This seventh in a series of monogenetic trematodes from the Southern Pacific Ocean discusses nine species of Monogenea from Australian waters. Redescriptions are given for Microcotyle arripis Sandars, 1945, M. bassensis Murray, 1931, M. helotes Sandars, 1944, M. nemadactylus Dillon and Hargis, 1965, M. neozealanicus Dillon and Hargis, 1965, M. odacis Sandars, 1945, M. pentapodi Sandars, 1944, and M. temnodontis Sandars, 1945. New locality records are reported for all of the above. New host records are established for Microcotyle bassensis Murray, 1931 and M. neozealanicus Dillon and Hargis, 1965. Microtyle sp. from the gills of Acanthopagrus australis (Gunther) is reported.

Monogeneans From The Southern Pacific Ocean, Polyopisthocotyleids From The Australian Fishes, The Subfamily Polylabrinae And Microcotylinae, W. A. Dillon, William J. Hargis Jr., Antonio E. Harrises

Reports

This sixth of a series on monogenetic trematodes from the Southern Pacific Ocean discusses five species of Monogenea from Australian waters. Polylabris carnivonensis n. sp., from the gills of Leiognathus fasciatus, and Polylabris sigani no. sp., from the gills of Siganus ormin, are described. Polylabris sillaginae (Woolcock, 1936) n. comb and Gonoplasius carangis Sandars, 1944 are redescribed. In order that comparisons can be made between Australian and New Zealand populations, Kahawaia truttae (Dillon and Hargis, 1965) Lebedev, 1969 is briefly I described.

Hydrodynamic Aspects Of Shark Scales, William G. Raschi, John A. Musick

Reports

The energetics of fish locomotion depends on a balance between thrust and drag. The interest stimulated by "Gray's Paradox", that is the seeming lack of sufficient power to overcome many of the estimated values of drag, has resulted in the delineation of a number of potential drag reducing mechanisms (Webb, 1975). Of particular interest is a variety of structural mechanisms, such as scombroid scale corselets (Walters, 1962) and scale ctenii (Burdak, 1969; Bone, 1972), which increase surface roughness and thereby alter boundary layer characteristics. Elasmobranch placoid scales, or dermal denticles, may perform such a function. Bone and Howarth (1966) have …

Dorsal And Anal Pterygiophore Interdigitation Patterns In Four Species Of Morone (Teleostei, Percichthyidae) : An Aid To Larval Identification, John E. Olney, George C. Grant, Fred E. Schultz, C. Laurence Cooper, John Hageman

Reports

The diagnostic potential of dorsal and anal pterygiophore interdigitation patterns was examined in larval stages of Morone saxatilis, M. chrysops, M. americana and M.mississippiensis. The number and position of pterygiophores relative to interneural spaces 1-6 and 10-13 and interhaemal spaces 12-15 as well as total number of dorsal and anal pterygiophores are characters useful in delimiting larvae of American Morone species. Interdigitation patterns useful in separating M. mississippiensis and M. americana larvae were not found, however these two species may not co-occur.

Deep-Sea Bottom Fishes Caught On The 14th Cruise Of The R/V Akademik Kurchatov, T. S. Rass, V A. Grigorash, V. D. Spanovskaya, Y. N. Shcherbachev

Reports

Captures of deep-sea fish in waters of the American Mediterranean Sea and adjacent Bahama-Bermuda region of the Atlantic Ocean prior to our work were performed by a series of expeditions: Coast and Geodetic Survey of the USA ("Blake," 1877-1880), New York Zoological Society ("Zaca" and "Arcturus," 1929-1931), Bingham Oceanographic Laboratory of Yale University, USA ("Pawnee," 1927), the Danish Carlsberg Foundation ("Dana," 1920-1922 and 1928-1930), Bureau of Commercial Fisheries, USA ("Oregon," "Oregon II" and others between 1950 and 1960), and the University of Miami ("Pillsbury," 1969). However, only the latter of these expeditions working in the region of the Puerto Rico …

Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov

Reports

The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.

Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky

Reports

The purpose of this report is to establish relationship among individual groups of parasitic flatworms, namely, among monogenetic trematodes (Monogenea), digenetic trematodes (Digenea), tapeworms proper (Cestoda), and the so-called Cestodaria group (AMPHILINIDAE and GYROCGTYLIDAE). The attempt to establish the above-mentioned relationships is made to a variable degree for different groups. The main point of this report is the establishment of phylogenetic relationship in the Monogenea, not only for the entire group as a whole, but also for the individual families which are members of this group. We feel that another important point is our attempt at clarifying the phylogenetic position …
