272 SPHAERODACTITUS 



scales of uneven size and with some scattered granules; the largest scales on 

 sides about seven, the smaller middorsals about ten or eleven equalling the dis- 

 tance from tip of snout to middle of eye ; no distinct middorsal zone ; anterior 

 loreals much enlarged, posterior loreals very small. 



Description: — Snout short, not very acute; the distance from tip of snout 

 to eye being about equal to distance of eye from ear-opening, and more than 

 twice the diameter of the eye ; rostral large with median cleft above ; nostril be- 

 tween rostral first upper labial and one supralabial and one small postnasal; 

 supranasals separated by a group of five, or four, small scales, two of which border 

 the rostral behind; suture between third large supranasal and the foiu-th very 

 small one, below centre of eye; over eye the usual spine-like scale; top of head 

 covered with very minute strongly keeled, very homogeneous granules, not en- 

 larged on the snout but on the neck increasing rapidly until the much enlarged 

 and heavily keeled almost tectiform dorsals are reached; laterals much larger 

 than dorsals but no well-defined middorsal differentiated zone; size of scales as 

 given in diagnosis; scales of chest keeled, of belly large, rounded, smooth and 

 imbricate ; scales of limbs enlarged, keeled and irregular in size ; scales of tail in 

 unreproduced portion in whorls of enlarged scutes with enlarged transverse 

 plates below^, in reproduced portion fine granular scales, pointed, not in regular 

 whorls and without large transverse plates below; mental large; bordered poste- 

 riorly by two enlarged scales, anterior gulars slightly larger than posterior. 



Colour: — Uniform rich brown with a conspicuous ocellus on each side just 

 over the axillar region. 



Dimensions: — Tip of snout to vent 30 mm. 



Vent to tip of tail ? (reproduced) 



Greatest width of head 5 . 5 mm. 



Tip of snout to ear 7 . 5 mm. 

 Fore leg 7 mm. 



Hind leg 9.5 mm. 



Remarks: — This species is allied to microlepis and vincenii but has a much 

 less differentiated area of dorsal scales and much larger scales throughout. I 

 have only seen one specimen but of this the colouration is uniquely different from 

 any Sphaerodactylus I have ever observed. Giinther called the Dominica indi- 

 viduals copii (sic) but an examination of Steindachner's excellent figm-e shows 

 that he had one of the species with the very well-marked middorsal zone and 

 apparently the Haitian form picturatus of Carman which must now be called
