are extremely shallow; they, as well as the intermediate spaces, are 
thinly beset with small sharp-pointed papille. 
The psalterium (P) is externally 1/°7 long and 1" wide, of the usual 
flattened oval or, more properly, kidney-shaped form. It contains 
within (fig. 8) nineteen deep crescentic lamelle, symmetrically

arranged, the largest, or those at the centre of the free convex border 
of the cavity, 4 an inch in height, their free edges all projecting 
equally, and, unlike those of Ruminants generally, without any inter- 
mediate shorter lamellee. The lateral surfaces and edges of the 
lamellae are thinly covered with small conical tubercles; but the 
bottom of each interspace is quite bare. This cavity communicates 
with the next by a distinct circular orifice *3" in diameter*. 
The abomasus (figs. 6 & 7 A) is of quite the usual form. Its 
lining membrane presents parallel, narrow, but much elevated, longi- 
* The description of the psalterium of the Musk-Deer by Pallas differs so much

attention of future observers may be directed to the subject.
