Leiocephalus personatus Cope. 

 Cope, Proo. Acad. nat. sci. Phila., 1862, p. 182. Boulenger, Cat. lizards Brit, mus., 1885, 2, p. 164. 



The striate head scales and other characters, as well as the absence of the 

 white lateral band or series of white spots, make one feel justified in keeping 

 this species separate from L. vittatus, although Boulenger remarked (loc. cit.) 

 that they were perhaps not specifically distinct. The solution to be expected 

 would be that this species replaced L. vittatus on San Domingo; one having no 

 specimens of L. vittatus from San Domingo would form this view. Boulenger, 

 however, recorded such specimens in the British museum; but it is possible 

 that these are really referable to L. personatus. At the time of writing the Cata- 

 logue, he had only one Cuban L. vittatus for comparison. 



The types of this species (M. C. Z., No. 3,615) are two examples in fair 

 preservation. More recently we have received it from Puerto Plata, San Do- 

 mingo, and from Furcy, Haiti. Cope based his species L. trigeminatus on the 

 young of this species, as he himself admitted (Proc. U. S. nat. mus., 1887, 10, 

 p. 438), after Boulenger had placed L. trigeminatus in the synonymy of L. perso- 

 natus. Although both species were described from Weinland's material, and the 

 types of both were said by Cope to be in the Museum of Comparative Zoology, 

 nevertheless the types of L. personatus only are to be found. 



Leiocephalus eremitus Cope. 

 Cope, Proc. Acad. nat. sci. Phila., 1868, p. 122. Boulenger, Cat. lizards Brit, mus., 1885, 2, p. 165. 



A species confined to the small island of Navassa, near Haiti. 



Leiocephalus herminieri (Dumeril et Bibron). 

 Dumeril et Bibron, Erpet. g<5n., 1837, 4, p. 261. Boulenger, Cat. lizards Brit, mus., 1885, 2, p. 166. 



This species was said by Dumeril and Bibron to have been sent to the Paris 

 museum from Trinidad by rHerminier, and from Martinique by Plee and Guyon. 

 Boulenger had only a skeleton from Martinique. Whether this creature has 

 been extirpated by the mongoose or not it is impossible to say. It is not repre- 

 sented in Carman's collection from Martinique, nor does it appear to have been 

 recorded from there in recent years. It is not known from any other of the 

 Lesser Antilles, which would make it seem possible that it was a Trinidad species 

 that had been erroneously credited to the fauna of Martinique.
