SYSTEMATIC ACCOUNT OF THE SPECIES. 123 
labial, a single small postnasal and a much larger supranasal which is separated 
from its fellow on the opposite side by a single much smaller median scale, these 
three bordering the rostral above; four large supralabials to the centre of the 
eye; a spine on the superciliary margin over the centre of the eye; head above 
and on sides covered with fine granules, those of the snout much enlarged and 
flattened; scales on back small and granular; mental large, larger than rostral; 
two large and one small roughly pentagonal chin-shields which are followed 
by flat, pavement-like scales which pass gradually into tiny round scales of the 
middle throat; belly with enlarged, smooth, rounded imbricate seales; tail 
with smooth, round, imbricating scales above and below, also a series of wide 
plates below on the median line. 
Colour (in life): — Uniform gray, lighter below; above finely punctate 
with white, streaked with fine white lines on side of head and neck. In some 
specimens the white appears as distinct vermiculations on the head and anterior 
body-regions; again the vermiculations may appear to be dark upon a light 
ground-colour; there is considerable variation. Never, however, has any 
tendency to cross banding been observed, the striping is invariably longitudinal. 
Dimensions: — Total length 76 mm. 
Tip of snout to vent 35 mm. 
Vent to tip of tail 41 mm. 
Greatest width of head 6 mm. 
Tip of snout to ear 9 mm. 
Fore limb 10 mm. 
Hind limb 11 mm. 
This gray Sphaerodactylus is by no means rare. Its habits are those of 
many others, found perhaps more often in houses than in the woods these little 
lizards become one’s familiar companions on many occasions. To show how 
widespread is the form we add the localities of the series in the M. C. Z.:— 
Herradura, Cabo San Antonio, Sierra de Cubitas, Los Negros in Jiguanf, Havana, 
Cienfuegos, San Diego de los Bafios, Caibarién, San Antonio de los Banos, also 
several localities in the Island of Pines and Haiti. 
This species has usually been called S. punctatissimus, but Duméril and 
‘Bibron’s description (Erp. gén., 1836, 3, p. 405) is based upon a specimen 
without locality, and is not sufficiently detailed to allow one to say surely that 
the name is applicable to this Cuban species without examining the type. 
For use of MacLeay instead of Cocteau for authority consult Stejneger 
(Proc. U. 8. N. M., 1917, 53, p. 266).
