THE HERPETOLOGY OF HISPANIOLA 91 



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

 tionships of Gonatodes notatus to the Cuban juscus. The smaller 

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

 olan lizard, 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 Hemidactyles, 

 type, "Gecko tuberculeux Daudin"). 



The species Hemidactylus mabouia and H. brookii are so easily 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 6 of these two forms as they occur 

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

 cable to the same forms in Hispaniola: 



a 1 . 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 2 . 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)
