Head oviform ; snout longer than tbe distance between the orbit and the ear-opening, once and two thirds the diameter of the orbit; ear-opening narrow, horizontal. Body and limbs moderately elongate, rather depressed ; digits broadly dilated, not very unequal, with a distinct rudiment of web, absent between the two outer toes. Sides of neck with irregular folds. Snout and interorbital space with very large, unequal, rough tubercles confluent with the cranial ossification ; hinder part of head, body, and limbs with very small, equal, granular scales, smallest on the throat. Rostral broad, quadrangular, with distinct median division above ; nostril pierced between the first labial and five or six small nasals, the anterior being much the largest ; nine to eleven upper labials ; mental small, triangular ; nine to eleven infralabials, gradually decreasing in size, inner pair nearly three times as high as broad, in contact behind the mental; a row of large scales behind the labials. Body and limbs covered with very small granular scales. Tail cylindrical, with uniform small flat juxtaposed scales arranged in verticils. Male with an irregular patch of very numerous praeanal pores. Head brown; the rest of the upper surfaces grey, dotted with darker ; lower surfaces dirty white, with scattered grey dots. millim. Total length 308 Head 38 Width of head 24 Body .. 115 Fore limb 50 Hind limb 66 Tail 155 This description is taken from two specimens in the British Museum and four others in the Brussels Museum. I have besides seen many others, including the specimen determined by M . Bavay as Platydactylus duvaucelii, D. & B. (This last-named species, of which! have examined one of the type specimens, belongs to a distinct genus, Hoplodactylus, Fitz.) The synonymy of this Gecko has been lately rather confused. |
