DR. E. LON'NBERG OX THE 



[Feb. 20, 



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

 in the Cervidas. 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 ' has only two, but 

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

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

 except Stiiga, which has four.

The ante-orbital pit or sinus sebacevs is well developed in Ovibos. 

 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.
