422 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Linguatulida: The larva of Porocephalus armillatus in Cercopithecus albogu- 
laris, Cynocephalus maimon, Macacus cynomolgus, M. fascicularis and M. rhesus, 
Mycticebus tardigradus, and Papio sphina, and the larva of P. moniliformis in 
Cynomolgus fascicularis. 
We have already called attention on page 412 to the haematozoa affecting 
primates. Other protozoa of man which have been found particularly infecting 
monkeys are Balantidiwm coli in Cebus variegatus, Cynomolgus fascicularis, 
Cercocebus fuliginosus, Colobus polykomos, in the baboon Papio sphinx, in the 
chimpanzee Anthropopithecus troglodytes, and in the orang-outang Simia satyrus; 
Entamoeba histolytica in Ateles geoffroyi, Anthropopithecus troglodytes, Macacus 
(Pithecus) philippinensis, and M. rhesus; Entamoeba coli, Endolimax nana, [oda- 
moeba williamsi in Macacus (Pithecus) philippinensis; Endamoeba gingivalis in Ma- 
cacus rhesus and M. cynomolgus. A number of intestinal flagellates have also been 
encountered in monkeys. In one instance Bruce and his co-workers found what 
they believed to be Trypanosoma gambiense in a monkey, Cercopithecus pygery- 
thrus centralis, from the shores of Lake Victoria.1_ Wenyon ? has given a list of 
the other trypanosomes which have been occasionally observed in monkeys. 
Hegner * has recently published a table of these and the other protozoan para- 
sites of man infecting both captive and wild monkeys. He points out that of 
the twenty-five species of protozoa recognized at the present time as inhabitants 
of man, seventeen of the twenty-five species have been reported from monkeys. 
These species were morphologically indistinguishable from the corresponding 
species that occur in man. Cameron ‘has recently compiled a list of the helminths 
of man which also have other animal hosts. His partial list of these includes those 
which infect the domestic animals as well as monkeys, and is therefore referred 
to here in connection with the subject of the parasites of animals in relation 
to human disease. 
Stiles ° has also prepared a Key Catalogue of Parasites reported for Primates 
(Monkeys and Lemurs) and their possible public health importance. This 
catalogue which appeared while this Report was in press, lists in many instances 
both natural and experimental infections, but the complete references are not 
published in this catalogue. 
GORILLA 
We requested permission to shoot but one gorilla as a specimen for the Zoo- 
logical Museum of Harvard University and the work of securing this specimen 
was assigned to Mr. Harold J. Coolidge, Jr., the assistant zoologist of the Ex- 
pedition. Mr. Coolidge not only secured an excellent specimen for the Museum 
but also performed a necropsy upon the animal and obtained specimens of a 
parasite in the intestine. He also prepared blood films from the animal’s blood.
