of the ileo-cxcal valve, this is produced by the considerable develop- 
ment of a glandular surface, which is quite as well marked in the 
Page 289. Giraffe (Camelopardalis giraffa), as was first pointed out by Dr. T. S. 
Cobbold, in his article “ Ruminantia,” in the Cyclopedia of Anatomy 
and Physiology,* where it is excellently figured, as it is also by the 
same author, although much less accurately, in the “ Proceedings ’’+ of 
this Society. I take the present opportunity of depicting its condition 
in Moschus, and have had placed side by side with it a drawing of the 
homologous gland in the Fallow Deer (Cervus dama), where it is com- 
paratively smaller (figs. 1,2). This gland is probably to be found in

having had my attention specially called to it, I have not taken the 
opportunity of looking for it. In future I will do so, and will inform

{ Since this paper was read I have examined the ileo-cxcal region of the colon 
in Alces machlis, where the gland is large and very much like that of the Giraffe— 
in Cervus virginianus, where it is oval, made up of shallow glands, and an inch 
long—and in Tragelaphus scriptus and Oryx beisa, where it agrees with that in 
C. virginianus.
