ON THE ANATOMY OF THE RUMINANTS. 399 
(Moschus moschiferus)* its penis is apparently ovine, as that of the 
Giraffe (Camelopardalis giraffa) (fig. 23).

Cowper’s glands are present, according to my observation, in Cer- 
vulus muntjac and Cervus mexicanus; and I have noted that they are 
small in OC. alfredi. Their absence I have recorded in C. elaphus, 
OC. dama, C. cashmeerianus, C. aristotelis, C. moluccensis, C. porcinus, 
C. kuhlii, and C. campestris. Prof. Flower found them in C. pudu. I 
have seen them also in all species of Ovis, Capra, and Gazella exa- 
mined, as well as in Cephalophus (mazwelli and pygmeus), Nannotragus Page 12. 
(nigricaudatus), Tragelaphus (scriptus), Damalis (albifrons), and Addaz 
(naso-maculatus). According to Dr. Murie they exist in the Prong- 
buck and Saiga; in Moschus according to Pallas, and in the Giraffe 
according to Prof. Owen.t 
In the uterus of the Cotyledontophora it is well known that there 
_are papilliform developments of the inner walls which serve for the 
attachment of the cotyledons in the impregnated organ. Although 
it has not been actually proved, so far as I am aware, by direct evi- 
dence that the cotyledonary papille and the cotyledons are exactly 
the same in number in each individual, yet there is every reason to 
believe that it is so. On this assumption I take the number of these 
papille as an index of the nature of the placenta itself, this being so 
difficult to obtain on account of the universal habit among the females 
to eat it immediately it is expelled, parturition generally occurring at 
night-time. 
The following Table contains a statement of the number of papille 
or cotyledons (as the case may have been) which I have found, together 
with those made by Prof. Turner on the same subject.t From it I 
feel justified in deducing the law that the cotyledons are few in 
the Cervide, numerous in the Bovidse—at the same time that I would 
suggest the name OLIGOCOTYLEDONTOPHORA for the former, and Poty- 
' COTYLEDONTOPHORA for the latter.
