DR. E. LON'MBEBG OX THE 



[Feb. 20, 



the fact that four teats are found in the Camelidas, in Giraffa, and 

 in the Cervida. That the teats in some forms have been reduced 

 independently is more than probable, when we take into considera- 

 tion the conditions presenting themselves in the Antelopes. In 

 the Bubaline section, for instance, Bubalis 1 has only two, but 

 Connoehcetes has four teats ; and a similar difference is also found 

 in the subfamily Antilopince, in which all the genera have two teats 

 except Saiga, which has four.

Udder of the female Musk-ox. 



The ante-orbital pit or sinus sebaeeus is well developed in Ovihos. 

 On the salted head of a cow I found the glandular organ to have 

 a lenticular shape, 23 mm. long, 18 broad, and 8 thick. It was 

 situated in a shallow groove of the lacrymal bone, in the angle 

 formed by the protruding orbital tube against the facial portion of 

 the skull. It is placed rather high, as it is on a level with the 

 upper third of the orbit. The interior of the pit itself is hairy, 

 and round it the glands are arranged and surrounded by a capsule 

 of connective tissue.
