MR. R. I. POCOCK ON THE EXTERNAL CHARACTERS 



is relatively short and stout, very thick at its proximal end, and 

 grooved throughout its length below. The apex is sharply 

 upcurled and transversely expanded into a hollowed, somewhat 

 basin-shaped disk, the rim of which is interrupted in front by a 

 channel, which is continued as a groove down the front of the 

 upcurved termination of the bone. This structure is perfectly 

 symmetrical in all its parts. (Text-fig. 18, B, E.)

In Gulo the haculum is relatively long and thin, without any 

 thickening at its proximal end and grooved beneath only at its 

 distal end, where it is gradually and lightly upcurled and decidedly 

 compressed. The apex bears a short, moderately high, com- 

 pressed, longitudinal crest, beneath which is a pair of short, 

 condyle-like processes separated by a deep cleft continuous with 

 the groove behind them. These processes are not symmetrical 

 and the crest is not upright. (Text-fig. 18, C, D.)
