220 DISEASE IN WILD MAMMALS AND BIRDS 
able to the formation of more sacculations; coproliths 
may form in the diverticula. The two monkeys now 
reported seem to have varying grades of the same con- 
dition, a long standing colitis with diverticula, constipa- 
tion and the collection of inspissated feces in the 
sacculations. These animals did not have hemorrhoids. 
Black Ape 9 {Cynopithecus niger). Coprostasis. Coproliths in 
diverticulum. Chronic colitis. Cor bifida. The large intestine is of 
the same calibre as the small intestine should be when not distended. 
The sacculations as seen before opening the organ are salient, forming 
distinct pouches. In one or two cases they are so pronounced as to 
constitute diverticula 7 cm. long. In two instances the serosa at the 
fundi of these diverticida is markedly hyperemic and very thin. In 
many cases the sacculations contain coproliths. The wall of the organ 
is distinctly thickened, puckered, inelastic and opaque. Mucosa is 
thrown up into coarse rugae. 
Japanese Macaque 6 (Macaciis fuscatus). Chronic hypertrophic 
colitis. False diverticula of colon. The large intestine contains a 
moderate quantity of quite constipated feces. The serosa is smooth. 
The wall shows at several stretches enlargements of the normal saccu- 
lations, forming false diverticula. The wall of the gut in these hernia 
is thinner than in the surrounding parts; no ulcers exist; no local 
peritonitis is present. The mucosa everywhere is irregular in thickness, 
less translucent than normal and thrown into irregular rugas; tenacious 
mucus covers it. No ulcers. 
TUMOKS. 
Only one tumor was observed in the mammalian intes- 
tinal tract proper. Dasyure {Dasyurus maculatus) 
Adenocarcinoma of the intestines. On postmortem there 
was a pale diffuse thickening of the coats of the small gut 
over a large area; numerous soft, light yellow, sharply 
circumscribed, elevated (like secondary tumors) nodules 
in the liver and spleen, and a pea-size whitish nodule 
around a bronchus in the right lung. Histological section 
of primary growth not made but a cross section of the 
intestine in the vicinity shows an adenomatous change 
with considerable increase in the connective tissue. The 
nodules in the liver, spleen and lung and the appearances 
of the abdominal lymph nodes, found microscopically, are 
precisely similar. They consist of irregularly arranged
