    ^ From the Proceedings of the Zoological Society o/ London, March 26, 18(51. 1 List of Entozoa, including Pentastomes, from Animals DYING at the Society’s Menagerie, between the years 1857-60 INCLUSIVE, WITH Descriptions of several New Species. ByT. Spencer Cobbold, M.D., F.L.S. (Plate XX.) During the interval above-mentioned I find that 122 different ani- mals have been specially examined by me with referenee to the pre- sence or absence of Entozoa. This number of individuals represents upwards of 100 distinct species, 38 of which (or, in round numbers, about one-third) were found infested. Of these 38 there are 19 mammals, 14 birds, and 5 reptiles. The mammalia harboured 6 trematodes, 8 cestodes, 5 nematodes, and 1 species of pentastome,— larval and immature forms being included. The birds contained 2 trematodes, 6 cestodes, and 14 nematodes; whilst the reptiles were in- fested by 2 flukes, 1 tape-worm, 6 round-worms, 1 acanthoceiihalous helminth, and 1 pentastome. Altogether I have found in 38 ver- tebrate species no less than 51 different forms of Entozoa, comprising 10 trematodes, 15 cestodes, 23 nematodes, I acanthocephalous ento- zoon, and 2 pentastomes. In very few instances can these parasites be said to have been the entire cause of death ; but in several cases they manifestly contributed to bring about that result, and in one instance their presence was the sole cause of death. This was evident in a Ring-tailed Lemur
