CARNIVORA 299 



species of Ascaris and a Trichosoma (T. entomelas) are not 

 uncommon in the intestines. In regard to the tapeworms, 

 Tcsnia tenuicollis infests the polecat and the common weasel, 

 and T. intermedia the pine-marten. The most common fluke of 

 the weasel is Distoma trigonocephalum. This infests the 

 intestine, while D. megostomum is found in the stomach. The 

 stoat or ermine (M. erminea) harbors Strongylus patens and 

 Tcenia brevicollis. 



The parasites of the f civets, ichneumons and their allies, 

 (Viverridae) are of little importance. Many years ago I 

 described a small fluke (Distoma compactum) obtained from the 

 lungs of the common Indian ichneumon (Viverra mungos). It 

 is figured in my ( Entozoa/ (p. 16). Two species of tapeworm 

 (Taenia platydera and T. genetics) have been found in the 

 common genet (V. genettce), and also a round worm (Ascaris bra- 

 chyoptera). From another viverra (V. senegalensis) Dujardin 

 obtained a strongyloid worm (Dochmius crassus). A species of 

 mongoos (Herpestes leucurus) is likewise infested by tapeworms 

 (Bothriocephalus folium). 



Comparatively speaking, very few entozoa infest the hyaenas. 

 In this family I include the earth-wolf (Proteles lalandi). 

 Some years back Prof. Flower sent me a large number of 

 delicate nematodes found loose in the peritoneal cavity of this 

 singular South African carnivore. The worms themselves were 

 so peculiar that I was compelled to form a new genus for 

 their reception (Acanthocheilonema dracunculoides). From the 

 intestines of the common Hytena striata Dr Lautner obtained 

 Echinorhynchus gig as. 



The parasites of the wolf, jackal, and fox family (Ganidce) 

 have especial interest, as including those of the dog. I can, 

 however, do little more than mention the names of the various 

 helminths of the dog, and the sources whence they come. At 

 the same time, I shall incidentally refer to the wild canine 

 animals that happen to harbor the same parasites. 



The flukes of the dog are few in number. 

 Perhaps the most important is Distoma conjunc- 

 tum, originally discovered by myself in an 

 American fox (Canis fulvus) that died at the 

 Zoological Gardens. Lewis, eleven years after- 

 wards, found it in the pariah dogs of India, 

 where it is of frequent occurrence. It infests the 

 bile ducts. As already stated, Prof. McConnell
