3-42 BARBOUR: ZOOGEOGRAPHY. 



Fitzinger's name Clelia, based on this very species of Daudin, antedates 

 the name Oxyrhopus of Wagler, in common use, by four years. 



Pseudoboa neuweidii (Dumeril et Bibron).

I have followed Boulenger (he. cit.) in using this name for the three small 

 snakes (No. 4511, M. C. Z.), from Grenada which Garman collected and recorded. 

 They agree perfectly with Boulenger's description of neuweidii, while they may 

 be distinguished at once from Schneider's species, coronatus, in that they have 

 each nineteen and not seventeen rows of scales. The original neuweidii of Dume- 

 ril and Bibron was apparently a composite species, and it has been divided by 

 Boulenger into the above form and 0. guerini Dumeril and Bibron. There is no 

 material at hand by which to verify this separation, but from Boulenger's descrip- 

 tions this solution of the question would seem to be excellent. 



The species has been taken only this once in Grenada, so far as I can find 

 published record. It is probably the same species as that recorded from Trini- 

 dad by Mole and Urich (Journ. Trinidad field nat. club, 1894, 2, p. 86) as Scytale 

 coronalum Schneider. It seems to be confined to these islands, besides being 

 widespread on the mainland. Its occurrence is to be expected on Tobago. The 

 fact that neither Allen nor Brues found or heard of it in Grenada last year would 

 suggest that it has probably been exterminated by the mongoose. 



I believe with Stejneger that the possession of undivided subcaudals is a 

 character of sufficient importance to warrant our separating these species generi- 

 cally from Clelia (Oxyrhopus auct.). Stejneger has shown that Pseudoboa is an 

 available name for these species (Proc. U. S. nat. mus., 1902, 24, p. 187-188).

The only specimens in the collection are the two from Jeremie, Haiti, col- 

 lected by Dr. D. F. Weinland, which served Cope as types for his /. vultuosa 

 (Proc. Acad. nat. sci. Phila., 1862, p. 73). They are No. 3,600, M. C. Z., 

 although Cope in the original description gave them as No. 1,519, M. C. Z. This 

 was the number from the old catalogue, which was long since discontinued, 

 unfortunately giving rise to confusion of numbers, and making the identification 

 of some of the early types a matter of difficulty.
