Osteomalacia. 
But three cases have occurred this year. Of these 
but one was a mammal — i. e., Cape hyrax (2715). The 
other two were birds — pigeon hawk (2721), and Vene- 
zuelan parrakeet (2799). 
Tumors. 
The number of neoplasms observed has been unusu- 
ally large. The occurrence in two undulated grass par- 
rakeets of the same type of neoplasm {Carcinoma simplex 
of liver) is unusually suggestive. All the tumors men- 
tioned below have been observed since the publishing of 
Dr. Fox's paper, reference to which has been made in 
this report. The zoological orders chiefly affected were 
the same as those mentioned in the paper, primates, 
lemures and anseres failing to show any tumors. The 
occurrence of neoplasms among the animals autopsied 
here show that tumors are not confined to man and 
domesticated animals, as is held by some. Eleven tu- 
mors have been found during the year, of which the 
following are brief notes: — 
2555. Undulated Grass Parrakeet {Melopsittacus un- 
dulatus) : 
Carcinoma simplex of liver, secondary carcinoma of 
spleen. 
The right lobe of the liver is enlarged posteriorly by 
a mass which extends upward over half of the right 
lung. Upon incising, the mass seems to be made 
up of gray-white, homogeneous, sharply outlined 
nodules. The left lobe contains two small similar 
nodules. There is a large rounded mass, similar 
to that in the liver, occupying the position of the 
spleen, but bearing no resemblance to the spleen 
tissue. 
Microscopically, very little liver tissue can be rec- 
ognized as such. Bile ducts are not demonstrable 
nor can any arrangement into lobules be made
