sharply defined, of the same width and are all equidistant from each 

 other. The belly is grayish and the rings do not extend beyond the 

 brown area. 



This species is similar in many respects to S. elegans MacLeay and S. 

 torrei Barbour from Cuba, in fact I believe the species are all three some- 

 what closely related. It is markedly different from the Sphaerodactyli 

 inhabiting the Virgin Islands and the Lesser Antilles and apparently also 

 from the little known S. sputator from St. Eustatius, for in writing of the 

 types, Andersson (Bihang till K. Svenska Vet.-Akad. Handl., 26, 4, 1900, 

 p. 27) speaks of " the large keeled scales of the back " which indicates a 

 species of a wholly different series. 



Size: in general appearance, i. e., with regard to size and habit espe- 

 cially, the type now described recalls at once S. elegans. It is a tiny 

 species unless the little creature before me is immature. Additional 

 specimens will be awaited with much interest. The type is 28 mm. in 

 total length, and but 14 mm. from snout to vent.
