Harold W. Manter Laboratory: Library Materials

During the summer of 1924 a study of marine fish parasites was made at the Mount Desert Island (Maine, USA) Biological Laboratory. The present paper represents a preliminary report on the trematode group. Three new species of trematodes are described. Only brief consideration is here given to species already known. A later paper will deal more completely with these and related forms.

Includes brief descriptions of Podocotyle atomon (Rud. 1802), Podocotyle olssoni Odhner 1905, Stephanochasmus baccatus Nicoll 1907, Lepidapedon rachion (Cobb.) 1858, Lepidapedon elongatum (Lebour 1908), Homalometron pallidum Staff. 1904, Steganoderma formosum Staff. 1904, Otodistomum cestoides (van Ben. 1870), Hemiurus …

Harold W. Manter Laboratory: Library Materials

A biographical overview of American parasitologist Joseph Leidy and his work. bron September 9, 1823, Philadelphia, Pennsylvania, USA - died 1891.

Conclusion

A detailed study of his writing justifies the statement that no one has yet adequately presented or fully elucidated Leidy's contributions to helminthology and his writing will furnish rich lead to many future workers in this field. How monumental the task of preparing a record of the full life work of this extraordinary man who in the same breath as it were, in a single letter records discoveries of far reaching import on bacteria, amoebae, worms, and fossil …

On A Species Of Hedruris Occurring Commonly In The Western Newt, Notophthalmus Torosus, Asa C. Chandler

Harold W. Manter Laboratory: Library Materials

It has recently been pointed out by Ward and Magath (1916) that the nematode fauna of North American freshwater fishes is almost unknown. From a survey of the literature this state of affairs appears to be almost if not quite as true of the nematodes of other cold-blooded vertebrates in North America.

While making stomach examinations of the Western Newt or water-dog, Notophthalmus torosus, the writer found a large percent of specimens captured in the vicinity of Corvallis, Oregon, infested by a nematode which was evidently a species of Hedruris. The structure and ecology of this worm are …

Otacariasis In The Bighorn, Henry Baldwin Ward

Harold W. Manter Laboratory: Library Materials

Summary

The ear of a mountain sheep at Estes Park, Colorado, USA, was found to be heavily infested with a Sarcoptid mite which was not the common scab mite of domesticated sheep but is new in this country.

This form is similar to a mite found in the ear of goats in the Pyrenees and in the Congo. Nevertheless there is reason to consider it a new species and it is named Psoroptes cervinae.

The complaint to which it gives rise is likely to be serious if its effects are like those of the related European form. The Bighorn …
