THE HERPETOLOGY OF HISPANIOLA 91 



Relationship. — Dr. Stejneger has satisfactorily discussed the rela- 

 tionsliips of Gonatodes notatus to the Cuban Juscus. The smaller 

 scales of the Cuban form separate it readUy enough from the Hispani- 

 olan hzard, which has conspicuously coarser scalation on the belly. 



More material is needed before making an adequate study of the 

 mainland relationships of Gonatodes notatus. 



Specimens examined. — As listed in table 15. 



Genus HEMIDACTYLUS Oken 



1817. Hemidactylus Oken, Isis, 1817, p. 1183 (based on Cuvier's H^midactyles, 

 type, "Gecko tuberculeux Daudin"). 



The species Hemidactylus mabouia and H. brookii are so easUy con- 

 fused that some of the literature pertaining to Hispaniolan records of 

 the one may really be attributable to the other. Maj. Chapman 

 Grant has recently made a study ^ of these two forms as they occur 

 in the Puerto Rican region and his key is copied below, as it is appU- 

 cable to the same forms in Hispaniola: 



a^. Six rows of spines around base of tail, dorsal pattern four black 



V's; femoral pores of males not interrupted at midline. mabouia (p. 94) 



a^. Eight or ten rows of spines around base of tail, dorsal pattern 

 brown, mottlings or four rings; femoral pores of males inter- 

 rupted at midline brookii (p. 91)
