for this particular collection are: LJ.S.N.M. ihjs. S1652-3 from the 

 north side of Guantananio Bay, Cuba, August 14, L930 ; nos. 81656-7 

 from Macola Hill in Guantananio Province. Cuba, August 15, 1930; 

 no. 81659 from Cusco Valley in Guantananio Province, Cuba, August 

 16, 1930; nos. 817 13-4 from Cayo west of Cachiboca, Doce Leguas, 

 Province of Camaguey, Cuba, September 8. 1930; and 81812-6 from 

 Boqueron, Cuba, August 19, 1930. 



The examination of the prefrontal scales makes this species rather 

 easy to tell apart from the other three members of the genus likewise 

 occurring on Cuba. Leiocephaliis raviceps has two prefrontals be- 

 tween the internasal and the supraorbital semicircle— the anterior 

 prefrontal small, the posterior considerably enlarged — while the other 

 Cuban species have three more or less subequal prefrontals. 



LEIOCEPHALUS VARIUS Garman 



Uoccphahis varius Carman, Proc. Amer. Philos. Soc, vol. 24, p. 274, 1887. 



U.S.N.lXr. nos. 81750-3 from Grand Cayman, September 15 and 16, 

 1930. 



TROPIDURUS TORQUATUS HISPIDUS (Spix) 

 Aganui hispida Spix, Spec. Novae Lacert. Bras., p. 12, 1825. 



U.S.N.M. nos. 79205-10 from the hill east of Pampater, Margarita 

 Island, September 8, 1929; no. 79228 from Los Robles, Margarita 

 Island, same day. The scales of the hands and feet appear to be 

 elongated into spines to a much greater extent in the Margarita Island 

 lizards than is the case in Venezuelan representatives, supposedly 

 of the same subspecies. A very thorough generic revision is necessary 

 before deciding how much weight can be attached to such a character 

 in a genus sul)ject to considerable specific variations as to structure 

 of scales. 



TROPIDODACTYLUS ONCA (O'Shaughnessy) 

 Norops onca O'Shaughnessy, Ann. Mag. Nat. Hist., Ser. 4, vol. 15 p. 280, 1875. 

 U.S.N.M. nos. 79226-7 from Los Robles, Margarita Island, Sep- 

 tember 8, 1929. 



The larger of these two specimens has been compared with the 

 types in the British Museum l)y H. W. Parker. He thinks that they are 

 the same, although he notes that in both type specimens the scales of 

 the sides are subimbricate and rather more lanceolate than in the 

 United States National Museum example.
