In our skuUs of X. unicinctus the distance from^the perforation 

 under the orbit to the end of the intermaxillary isl| inch ; in Gie- 

 bel's figure it is ly'^ inch. 



I have not seen this species. The skuU figured by Giebel is that 

 of a Xenurus, judging from the constriction of the brain over the 

 orbit ; but the face is very much shorter than in the skulls of X. 

 unicinctus in the British-Museum collection.
