slightly larger nasals. The cranium is arched in a similar manner 

 with the same sharp decline of the parietal to the supraoccipital, and 

 has the small sagittal elevation anterior to the parietal suture. Also 

 the depression is less in the posterior portion of the frontals. The 

 antorbital fossa is not so wide nor deep as that of the male, but the 

 antorbital vacuity is very extensive. The auditor}' bulla; are very 

 large, resembling in this respect those of C. porcinns.

I have refrained from giving a name to this species and so possi- 

 bly escaped adding a useless synonym, for the reason that Mr. 

 Worcester writes me he thinks it probable that P. Heude has described 

 it already. His paper, which may contain a description, is entitled 

 " Problema Philippinense sur Cervinorum, Cranium, etc., Memoires 

 concernant l'Histoire Naturelle de l'Empire Chinois, Zi-Ka-\Yei, 

 1887." I have never seen this paper, and am not aware if there is a 

 copy in this country, but it seems to include all specimens of Philip- 

 pine deer under various appellations. I can only give the above 

 descriptions of the examples in the collection of this institution, trust- 

 ing that some more fortunate fellow-worker maybe able to fit them to 

 one of P. Heude's names. 



Nycticebus tardigradus (Linn.) 



A skin of a female from Bongao. The skull exhibits but two 

 incisors in upper jaw which is considered a character of X. javanicus.
