and another behind the hind limbs, four on tail, the two distal rings more or less 

 broken into dots; tip of tail pale. The rings are very sharply defined, equi- 

 distant from each other. The belly is gray and the rings do not extend beyond 

 the brown areas of the sides. 



Dimensions: — Adult. Tip of snout to vent 54 mm. 



Vent to tip of tail 28 mm. 



Greatest width of head 5 mm. 



Tip of snout to ear 5 mm. 



Fore leg 6.5 mm. 



Hind leg 9 nam. 



Remarks: — I described this species from a single specimen which proves to 

 have been a very young one. Its scales on back and shoulders were so tiny as to 

 appear really granular. Hence, I associated it with elegans and torrei and con- 

 cluded that it might easily be adult for elegans is excessively small and strikingly 

 similar in colouration. In 1918, however, Mr. W. R. Forrest sent me five addi- 

 tional sphaerodactyls from English Harbour, Antigua. Two tiny j'oung, one 

 half-grown and two large specimens. Of these five specimens the males are 

 absolutely plain uniform brown in colour, the females are speckled, "pepper and 

 salt" colom*. The two little examples which are very small agree closely in size 

 but not in colour, with the type, i. e. being about 30 nun. in total length and with 

 it they agree remarkably in scutation. The middorsal granidar zone which is 

 really not particularly well defined is only seen under high magnification. The 

 adults, however, completely change the deduction as to affinities and it is clear 

 that this form belongs with pidus, sputator, and allied species.

Type-locality: — St. Vincent. 



Types: — M. C. Z. 10,788 one specimen. One of the Cotypes from the 

 British Museum. 



Distribution: — Confined to the Island of St. Vincent. 



Diagnosis: — Medium sized, having keeled scales on chest and perfectly 

 smooth scales on the belly; small keeled scales on sides of back about twelve 

 equalling the distance of tip of snout from centre of eye; scales of middorsal 

 region reduced in size but not to form a well-defined granular zone.
