ANIMAL PARASITIC INFECTIONS 415 
Annam. While this parasite resembled P. malariae morphologically, it was not 
inoculable either into man or other animals. 
The following list compiled by Theiler, the zoological determinations being 
made generally by Allen, gives the animals in which Haematozoa were observed 
during the Expedition: 
Plasmodium Haemoproteus 
Cercopithecus diana Agama colonorum 
Cercopithecus nictitans Kingfisher, 186, Halcyon senegalensis 
Colobus rufomitratus fuscopileus 
Petalia grandis Bird, 51, Gymnobucco calvus calvus 
Bird, 55, Pyromelana hordacea hor- 
Haemogregarine dacea 
Crocodilus cataphractus Bird, 64, Streptopelia semitorquata 
erythrophrys 
Bird, Bee-eater, Melittophagus gula- 
ris gularis 
Osteolaemus tetraspis 
Tree Snake Specimen not identified. 
Dendraspis viridis 
Bufo regularis 
From this list it may be seen that we did not find plasmodia in other mammals 
than monkeys. Some years ago Bruce ! and his co-workers found a Plasmodium 
in the blood of the duiker in East Africa resembling P. malariae in morphology 
which they named P. cephalophi. Sheather ? in India also encountered a Plas- 
modium in the blood of the buffalo resembling P. malariae which he called P. 
bubalis, and De Mello and Paes * have described one in the blood corpuscles of 
goats which they named P. caprae and which morphologically resembled P. 
falciparum. In addition Castellani and Chalmers* have reported upon a 
Plasmodium in dogs in India, P. canis, resembling morphologically P. vivax in 
man, and another species in the horse P. equi. Some of these parasites have been 
illustrated recently by Wenyon.> We have had no experience with any of these 
species in the larger mammals and regard them as either exceedingly rare or in 
some cases as perhaps mistaken observations. Although blood examinations 
were made of all the wild game that we shot in Africa, no Plasmodium was found 
in any of them. 
A number of piroplasmata have also been described in mammals. Those 
which have been discovered in carnivora are: Babesia canis (Piana and Galli- 
Valerio, 1895) in the dog, Canis familiaris; B. gibsoni (Patton, 1910) in the 
jackal, C. aureus, and B. rossi (Nuttall, 1910) in the African jackal, C. adustus; 
B. herpestidis (Franca, 1908) in the Portuguese mongoose, Herpestes ichneumon, 
and B. legeri (Bédier, 1924) in the African mongoose, H. galera; B. bauryi 
(Leger and Bédier, 1922) in the fox, Fennecus dorsalis; Nuttalia civettae (A. & M. 
Leger, 1920) in the Senegalese civet-cat, Viverra civetta Pucheran; and Babesia 
felis in the Sudanese wild cat, Felis ocreata (Davis, 1929). Davis ® has shown
