comparison, I have generally found the descriptions of Dr. Baird the 

 most accurate and trustworthy. 



To facilitate this object, I have added a list of the species the 

 skulls of which have been figured.

Description of a New Genus of Boid^e from Old Ca- 

 labar. By Dr. J. E. Gray, F.R.S., V.P.Z.S., etc. 



Mr. Logan has kindly sent to me for examination a number of 

 Snakes and other reptiles which had been collected by the mission- 

 aries in Old Calabar. 



Among several very interesting species I observed a new genus of 

 the family Boidce, which I have great pleasure in laying before the 

 Society, more especially as it appears to be the indication of a new 

 tribe in that curious family. 



This animal belongs to the second section of the family, which is 

 thus characterized : — 



ii. Tail very short, not, or only very slightly, prehensile. Head 

 indistinct, short. 



It is entirely distinct from the tribes Cylindrophina, Carinina, 

 and Tortricina, and therefore I propose to form for it a tribe (Cala- 

 hariina) by itself, having the same characters as the genus.
