they all three do from F. Cuvier's statement. (Cétacés, p. 86.) 
Lower half, generally about the size of the fore-finger, increas- 
ing somewhat downwards, though, for the last foot or more, it 
becomes much smaller ; upper half, to a considerable extent, 
smaller than the little finger, though longer at the very upper 
part ; according to F. Cuvier, the diameter of the intestine, in 
the * dauphins et marsouins,” is regular, diminishing but very 
little from the pylorus to the anus; these would include the 
Present. specimen and the globiceps, as well as the dolphin, 
and yet his remark is not confirmed in either case. The dila- 
tation at the commencement of the intestine was strongly 
marked : 4! inches long, and 23 inches transversely at com- 
mencement; parietes about as thick as the intestine below, 
ut the mucous membrane of the two differed greatly in 
structure, and the change was rather abrupt, though there was 
no contraction nor anything like a valve. The mucous mem- 
brane of the dilated part was quite smooth, polished, some- 
what transparent, and, after being in spirit for one night, 
showed several opaque points which were evidently glands, 
Whereas that of the intestine immediately below was just the 
reverse, opaque with marked longitudinal rugz. These rugæ 
extended more or less throughout the intestine, but were not.

inches in length ; the follicles, which were small, and very

intestine, but upon a distinct fold, which was attached to 
~ mucous membrane by its centre only. Cuticle continued 
about 3 inches within the rectum. Some inflammation and en-
