gonal, in contact behind with first lower hibials and one pair of large 

 postmentals, wliich are followed by another pair of equal size not in 

 contact with each other ; 7 larger lower labials which are bordered by 

 a series of enlarged granules; bod}^ and legs above covered with small 

 uniform granules; body and extremities below, as well as upper 

 surface of feet, covered with larger imbricate scales, those, on throat 

 and untlerside of lateral fold, however, smaller, scarcely larger than 

 the dorsal granules; from axilla to groin a thin skin flap about 2 mm. 

 wide, and a similar fold along the posterior edge of thigh and tibia; 

 five pairs of plates under shortest toe and eight pairs under longest; 

 four toes nearly half webbed, hallux free; tail flat, with sharp, almost 

 fin-like, and serrated edges, and a strong basal constriction; it is 

 'covered with somewhat pointed imbricate scales and underneath 

 with a median series of about 40 wide subcaudal plates; at the basal 

 origin of the flap-like lateral expansion of the tail a number of well- 

 differentiated elongated spines; femoral pores continuous from knee 

 across the belly, 20 on each side. Color (in alcohol) above <lrab with 

 indistinct marblings of darker and lighter color; a distinct dark 

 band from loreal region through lower part of eye and above ear to 

 shoulder; below whitish.

Remarlcs. — From the above description it will be seen that the For- 

 mosan specimen agrees m all essential points w^ith those fi'om other 

 localities. The second pau* of postmentals is unusually large, but I 

 have before me (m Bergen Museum) a specimen from Luzon, in the 

 Pliilippmes, which is halfway in this respect between normal speci- 

 mens and the Formosan specimen. 



Habitat. — Tliis gecko is widely distributed from India and the East 

 Indian Archipelago to southern China and the Philippines. So far as 

 I know it is here recorded from Formosa for the first time. It was 

 collected in the early sixties b}^ Captain von der Ohe, from Bergen, 

 who during his eastern cruises collected extensively for the museum in 

 liis native city.
