RHINOCEROS OF THE SUNDERBUNDS. 149 
sented in Fig. 1 [p. 148], where they are seen to consist of flattened, 
round-tipped processes of the mucous membrane, several of which are 
blended at their bases, in transverse lines. None are more than ‘3 of 
an inch in length, and most about “6 inch broad where they first 
become free. They give the impression of being incomplete valvule 
conniventes which have been cut and deeply jagged at their free edges. 
The opéning of the bile-duct is 7 inches from the pylorus, being a 
nipple-like tubular projection, nearly an inch long, among the papille. 
From the spot where they commence, all the way to the ileo-cxcal 
valve, these papille are found—those near the last-named situation 
differing from those in the duodenum in being more scattered and 
freer from one another, many in the ileum springing independently 
from the mucous membrane. Nowhere, however, are they otherwise Page 711. 
than flattened, broad, and blunt-tipped, none anywhere being circular 
and slender like those in the ileum of R. unicornis,* the existence of 
which I have had the opportunity of verifying. They never exceed

‘3 of an inch in length. Numerous Peyer’s patches exist in the 
ileum, as may be inferred from Fig. 2, which is a representation of
