Extract

Some new species of Mastigophora and Sporozoa and a Microfilaria, parasitic in fish, frogs and toads in eastern Canada, are described and illustrated.

Trypanosoma percae n.var. canadensis from the yellow perch, Perca flavescens, is monomorphic, smaller, with a shorter, broader body and shorter free flagellum than Trypanosoma percae from European Perca fluviatilis. Trypanosoma myoxocephali n.sp. from the longhorn sculpin, Myoxocephalus octodecimspinosus, is small, with a narrow undulating membrane. It is the first trypanosome to be recorded from Myoxocephalus. Trypanosoma lavalia n.sp. from Bufo americanus is delicate, with a prominent undulating membrane with two myonemes. Trypanosoma gaumontis n.sp. from Bufo americanus is small, crook-like, with undulating membrane with deep folds and one myoneme very-near the bordering flagellum. There is no free flagellum. Trypanosoma montrealis n.sp. from Bufo americanus is long and sinuous, with very short free flagellum and without chromatoid granules in the cytoplasm.

Trypanosoma rotatorium (Mayer) is described from Rana catesbiana from eight sites, R. clamitans from three sites, and R. pipiens from three sites in Quebec Province. Trypanosoma inopinatum Ed. & Et. Sergent is recorded from Rana catesbiana and R. pipiens, A form similar in dimensions and morphology except for a much shorter free flagellum has been found in R. catesbiana from St Eustache.

Spirochaeta manitoui n.sp. is described from the blood of Rana catesbiana from Lake Manitou.

Lankesterella canadensis n.sp. from Rana catesbiana from Montreal and Lake Manitou is described and illustrated. Intracorpuscular forms have polar vacuoles, schizogony occurs in endothelial cells of the blood vessels of the liver and kidney, and multinucleate oocysts have been observed.

Haemogregarina myoxocephali n.sp. from the longhorn sculpin, Myoxocephalus octo-decimspinosus, and Haemogregarina urophysis n.sp. from the white hake, Urophysis tenuis, are described. Two other haemogregarines sens lat. from species of Rana and Bufoamericanus are described, Haemogregarina aeglifini Henry is recorded from a new host, Gadus callarias from off Labrador, Haemogregarina platessae Lebailly from Pseudopleuronectes americanus and Haemogregarina bigemina Laveran & Mesnil from the eel pout, Zoarces angularis, the hosts being new.

Plasmodium catesbiana n.sp. from Rana catesbiana from the Back River, Montreal, is a small species, with ‘signet ring’ and amoeboid trophozoites, schizonts with up to eight merozoites clustered round coarse pigment granules and gametocytes showing slight sexual dimorphism. Plasmodium bufonis n.sp. occurs in Bufo americanus from Laval des Rapides. The schizonts are large, oval, and give rise to eight merozoites arranged en barillet, the pigment usually being at one pole. Possibly micro- and macromerozoites may be produced. Macrogametocytes are oval and deep-staining; microgametocytes are vermicular. Both have pigment.

A haemosporidian, different from but probably allied to Haemogregarina bigemina, is described from the black sea bass, Centropristis striatus.

Haemoproteus laurentiae n.sp. occurs in Bufo americanus from the banks of the St Lawrence at Montreal South and at Lake Manitou. Its pigment is characteristic, consisting of rod-like or bacilliform distributed granules. Haemoproteus lavalia n.sp. from Bufo americanus, from Laval des Rapides, has pigment restricted to curved bands of rounded to somewhat angular granules. Uninucleate parasites have been observed in extremely few endothelial cells of the lungs. Haemoproteus lanoraiea n.sp. from Bufo americanus, from Lanoraie, has very pale yellow to light brown pigment granules, densely crowded at one pole and forming a compact granular cap. Oval parasites have been found in endothelial cells of the lungs.

Leucocytozoon salvelini n.sp., parasitic in the leucocytes of the speckled trout, Salve-linus fontinalis, is described.

Dactylosoma salvelini n.sp., parasitic in Salvelinus fontinalis from a Laurentian stream, is the second species of Dactylosoma to be described and the third to be notified from fish. It has fan- to wedge-shaped schizonts producing eight merozoites. Its gametocytes are not markedly different from one another in shape but differ in cytoplasmic staining and in nuclear structure. Dactylosoma sylvatica n.sp., parasitic in Rana sylvatica from near Quebec City, produces eight merozoites and has oval and reniform gametocytes.

The morphology of a Microfilaria from Rana sylvatica is described.

The effects of the Protozoa on the host cells are described for each organism, and some differential leucocyte counts for comparable normal and parasitized Amphibia are given in the concluding section.
