402 PARASITES OP ANIMALS 



quently encountered both in India and Africa. To Mr Spooner 

 Hart, of Calcutta, I am indebted for a large number of speci- 

 mens; their size exceeding that of any other bots that have 

 come under my notice. Probably this parasite infests the 

 stomach of rhinoceroses generally ; at all events, it occurs in 

 R. unicornis, R. bicornis, and R. simus. At present the imago 

 is unknown. The longest Iarva9 in my possession measure 1J", 

 but Brauer records specimens up to 35 mm. in length by 10 

 mm. in thickness. In African hosts M. Delegorgue found 

 these parasites in prodigious numbers.

Very little has been written respecting the parasites of the 

 Hippopotamida and Tapiridte. I think it was Livingstone who 

 first drew attention to the fact that the river-horse or sea-cow 

 is much infested by tapeworms, but I have not seen any 

 published description of the worm. Dr. Murie, during his 

 sojourn in Egypt, found a solitary bot embedded in the soft parts 

 surrounding the eye, and judging from his figure the species is 

 new to science. Provisionally I speak of it as the Hypoderma 

 Muriel. In the paper (quoted below) Murie appends a list of 

 all the animals in which bots have been found. Though chiefly 

 taken from Brauer, it is useful and tolerably complete. So far 

 as I am aware no cestodes have been described as infesting 

 tapirs ; nevertheless, at least five other kinds of helminth have 

 been found in Tapirus Americanus. Of these, two are flukes 

 (Amphistoma asperum and A. pyriforme), and three are nema- 

 todes (Sclerostoma monostechum, Spiroptera mediospiralis, and 

 Sp. chrisoptera). The three species first named occupy the caecum,
