Show 118 MR. G. A. BOULENGER ON T H E [Mar. 6, II. Digits more or less dilated, all but the inner with the distal joint compressed, short, clawed. A. Inner digit clawless; two series of oblique infradigital lamellas divided by a median groove 3. Lepidodactylus, Fitz., p. 120. B. Inner digit clawed ; infradigital lamellae transverse, not divided by a groove; tail prehensile 4. Rhacodactylus, Fitz., p. 123. III. Digits strongly dilated, without compressed distal joint, all furnished with transverse, undivided lamellae inferiorly; upper surfaces covered with large, fiat, platedike scales; tail prehensile 5. Eurydactylus, Sauvg., p. 129. IV. Digits not dilated, slightly depressed at the base; the distal phalanges slender, compressed, clawed, with a series of transverse plates inferiorly 6. Gymnodactylus, Spix, p. 129. 1. HEMIDACTYLUS, CUV. 1. HEMIDACTYLUS GARNOTI. (Plate XXII. figs. 1, la.) Hemidactylus garnotii, Dum. & Bibr. Erp. Gen. iii. p. 368; *Bavay, Cat. p. 13. Doryura garnotii, Gray, Cat. Liz. p. 157. Hemidactylus ludekingii, Bleek. Nat. Tijds. Ned. Ind. xvi. 1859, p. 27. This species, first discovered in Taiti, is mentioned by M . Bavay as being found in N e w Caledonia; and I entertain little doubt as to the correctness of the identification. The following characters are taken from three specimens in the British Museum (South-Sea Islands, Philippines, Agam) which agree in every point with Bibron's original description:- Head much longer than broad; snout obtusely pointed, longer than the distance between the eye and the ear-opening, once and two thirds the diameter of the orbit; forehead slightly concave ; ear-opening small, rounded. Body and limbs moderate, depressed. Digits free, or with a very slight trace of web, moderately dilated. A slight but distinct fold of the skin along the flanks, and another bordering the hind limb posteriorly. Upper surfaces and throat covered with minute granular scales, a little larger on the snout; abdominal scales moderate, imbricate. Nostril pierced between the rostral and three small nasals; twelve upper and nine or ten lower labials; mental large, triangular, in contact posteriorly with a pair of pentagonal chin-shields, followed by a second smaller pair; the anterior pair of chin-shields in contact with the first infralabial and with its fellow mesially ; the posterior pair separated from each other and from the labials. Tail elongate, depressed, narrower than the body, with sharp denticulated lateral edge; the scales on the upper surface very small, equal; those on the lower surface larger, imbricate, with a median series of large, transversely dilated plates. Brownish-grey above, uniform or with small indistinct darker spots ; lower surfaces uniform whitish. |
