variable nature of this small hepatic appendage, even in the same 
species. 
P With reference to the generative organs, Pallas records the exis- 
tence of Cowper’s glands and a filiform termination to the urethra, of 
some length. I take the opportunity of figuring the glans penis, as 
the drawings given by Pallas, although particularly instructive, are 
too small to exhibit some of its characteristics (fig. 3). The glans,

on the whole, is more like that in the genera Gazella and Addaw' than 
in Ovis, Capra, Cephalophus, and Camelopardalis, in all of which there 
is a filiform termination to the urethra. The Cowper’s glands were 
about the size and shape of haricot beans, one on each side. The 
vesciculse seminales were each an inch long, and of a fairly uniform 
breadth of 4 inch. The urethral ends of the vasa deferentia were 
considerably dilated for a little more than an inch and a half. 
As has been clearly described by Pallas, the musk-sac opens a short 
distance in front of the preputial opening; its size is nearly that of an 
ordinary orange. Inthe specimen under consideration it was filled with 
adark-brown, chocolate-coloured powder, possessing, most powerfully, 
the characteristic odour. Its minute orifice was a little more than 
half an inch in front of the opening of the prepuce, from which latter 
a few stiff hairs, about half an inch long, projected forwards and 
downwards. The two orifices were included within a common 
sphincter muscle, the skin over which was covered with fine hairs, ali 
radiating towards its centre. The slightly convex cutaneous surface 
included within the sphincter was devoid of hair. This account 
agrees with that of J. F. Brandt and J. C. T. Ratzeburg in 1839?; 
and my specimen in no way differs from the excellent figures of the 
musk-sac given by those authors. 
In my paper on the visceral organs of the Ruminantia®, I have 
drawn special attenticn to the nature of the internal surface of the 
uterus in the Order, having given strong reasons for the surmise that 
the Cavicornia are characterized by having numerous cotyledons on 
the placenta, on which account they are termed Polycotyledonto- 
phora, whilst in the Cervidee (therefore termed Oligocotyledonto- 
phora) the cotyledons are very few innumber. It occurred to me that 
the nature of the interior of the uterus or the placenta would throw 
much light on the very disputed point as to the affinities of Moschus. 
Of the placenta Pallas tells us* that “cotyledones et respondentes 
placentul@ oblonga, plana figura gaudent et in series fere digeruntur.
