474 DISEASE IN WILD MAMMALS AND BIRDS 
Two endotheliomata have been found, one of the flat 
variety with, warty excrescences common on serous sur- 
faces, located in the pleura of a leopard {Fells nebulosa), 
and one of the nodular variety, growing from the clavicle 
of a Moorhen (GaUinula chloropus) . 
The sarcomata present their usual morphology 
grossly and minutely and with the exception of the cases 
arising from the pectoral muscle and from the genital 
area offer little of interest. Two instances in the former 
location, observed in parrakeets, presented several puz- 
zling features. The component cells were spindle in shape, 
similar to a muscle cell but were fitted with the round or 
elliptical nuclei of embryonal cells. In a few places they 
were exceedingly large and had shadowy outlines like a 
syncytium or they would be so arranged as to suggest a 
glandular structure. The dominant type of cell was, how- 
ever, everywhere the spindle as it is seen in sarcoma. The 
sarcomata when they occur in the genital area usually 
assume the alveolar arrangement and are of the round or 
mixed cell variety. Only three of the sixteen sarcomata 
gave metastases. 
Papillomata of minor character appear occasionally 
on the skin of animals as warts, but only one instance of 
any greater importance has been found. The duodenal 
mucosa of an owl {Bubo virginiamis) presented a soft 
growth which partly obstructed the intestinal lumen. 
Papillary adenomata, on the other hand, have been 
obser\"ed several times, but since they have more 
importance as irregular hyperplasias of glandular origin 
have been included in the next group. An interesting 
case was seen in a baboon {Papio hamadryas) in which a 
large part of the gastric wall was the seat of adenomata, 
presenting in addition several distinct papillary out- 
growths. A similar picture was found in the duodenum 
of the rhea {Rhea amerieana). 
The greatest interest in the adenomata centres around 
these gro\\i;hs in the renal area in parrakeets, and as they
