Notes On North American Myxosporidia, Henry Baldwin Ward

Harold W. Manter Laboratory: Library Materials

In this paper are published data on three new species of Myxosporidia. Two species were observed in Lake Erie as parasites of a minnow; the third came from a species of Pacific salmon. Both cases present some unusual features that seem worthy of record.

Included are descriptions of Myxobolus aureatus nov. spec., Henneguya brachyura nov. sp., and Henneguya salminicola nov. spec.

I am greatly indebted to my colleague, Dr. Rokusaburo Kudo, for valuable assistance given while I was working up the material. The beautiful sketch illustrating the species from Lake Erie was prepared by Mrs. H. S. Jennings, to whom …

On The Specific Identity Of Heronimus Chelydrae Maccallum And Aorchis Extensus Barker And Parsons, Horace Wesley Stunkard

Harold W. Manter Laboratory: Library Materials

The monostomes are among the least known of North American trematode groups. Records give descriptions of only six species, each the single representative of a genus, and according to the classification of Ward (1918) belonging to four different families. Existing descriptions in most cases are far from complete and data necessary for taxonomic determination are lacking. This deficiency has been pointed out by other workers, both in this country and in Europe, and the classification of the monostomes is not well established. In fact, certain investigators regard them as aberrant forms, sprung from different distome groups, which alike have lost …

Winthrop Davenport Foster's work in parasitology was done principally on the parasites of swine and along the lines of critical tests of the efficacy of anthelmintics, though he published a number of notes on other lines.

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 …
