Infected Parasitic Cyst in Phillipine Spotted Deer 
(Cervus alfredi). 
In the past years we have found many examples of 
parasitic cysts, notably Cysticercus tenuicollis, among the 
herbivora, including deer, goats, and camels, but in 
none could they be considered as concerned in causing 
the death of the animal. It seems particularly unfor- 
tunate that such a valuable animal as the above should 
have been the first and sole victim of the disease. The 
lesion, found in the gastro hepatic omentum, con- 
tained a small quantity of pus and partly disintegrated 
membranous walls of a cysticercus. Around it there was 
a zone of dry but unmistakable peritonitis extending 
some five or six inches into the peritoneal cavity. This 
animal had been in the garden but seven weeks, too 
short a time for the disease to have been acquired here. 
These cysts can be acquired only by ingesting one of the 
eggs of the dog tapeworm, Tcenia marginata. The case 
teaches us that we should not regard these cysts too 
lightly and that we should, from this, watch our Canidse 
for these tapeworms. A similar warning was sounded 
in the report of 1913 (page 38) where Gray Wolf No. 3 
was noted as passing tapeworm eggs, isolated, treated, 
cured (1914 Report, page 38) and passed back to exhi- 
bition. 
A special paragraph seems proper on the arachnoid 
parasite Pneumonyssus foxi, found in the lung of a 
rhesus macaque (No. 3156) which forms a basis of the 
two papers heretofore mentioned as being published 
from the laboratory. The latter one gives the technical 
diagnosis of a new species, while the former states the 
case and gives literature on the subject of arachnoid 
endoparasitism in monkeys and man. The points 
brought out which are of especial interest to the garden 
were that 
1. Four different species of arachnoid (not counting 
our own case) have been described from monkeys' lungs,
