or chrome-yellow margins. The tail with 8 or 9 complete rings of similar colour, without the margins. Beneath : throat and belly whitisli yellow, or pale brownish, cach scale minutely dotted with brown. Pupil vertical, dentilated ; iris golden, finely vermiculated with Van Dyke brown.

HABIT.Pinang Hills.

Singapore.
In the male the two rows of femoral pores commence as two short
parallel longitudinal lines, separated from each other by a narrow short
furrow, on the sides of which, (vertically,) the first 5 femoral (preanal),
pores are placed. In, front of the anus the hort vertical portions
turn right and left under a nearly right angle, continuing the entire
length of the thigh, each supporting 13 more femoral pores. The interval
between the anus and the latter is partly occupied by a flat, slightly
raised triangular space, covered by rather large, imbricate, rounded
scales. In the female the two lines of larger scales carrying the femoral
pores of the males, are present, each scale having a small shallow,
round depression. The short, longitudinal furrow of the male is either
wanting or barely distinguishable, but the triangular space with larger
scales, in front of the anus, is present. The species appears to be
rather numerous on the hills at Pinang, where the individuals obtained
were captured in houses, at an elevation of 2,200 feet. The largest
male was of the following dimensions :

Its habits offer nothing peculiar : it bites fiercely in defence. In captivity it refuses insects. The integuments, when about being renewed, are piecemeal torn off by the teeth, and devoured. A single egg deposited was of a spherical form, about half an inch in diameter, of a whitish yellow colour. M. M. Duméril and Bibron assign Bengal as the Habitat of this species. The specimen originally described by Mr. Gray, some in the Museum of the Asiatic Society, and a number in my own collection, all are from the hills of Prince of Wales Island (Pulo

Pinang,) but no authenticated record exists of this species ever having been observed in Bengal. Another, widely different species of Gymnodactylus inhabits Bengal, as yet not published, and only known from three specimens, preserved in spirits in the Museum of the Asiatic Society, where they are marked Gymnodactylus lunatus, Blyth. One of these came from Midnapore, the others from Chyebassa. The species somewhat approaches to G. fasciatus, Dum. and Bibr. (Cubina fasciata, Gray.) The Museum possesses another nondescript species from Almorah, Gymnodactylus nebulosus, Blyth, MSS. allied to G. marmoratus, (Gray).

The plate of Cyrtodactylus pulchellus in Gray's Illustrations of Indian Zoology is not taken from life, and gives a most inadequate idea of the physiognomy and beauty of the living animal. This should be observed, as M. M. Duméril and Bibron praise the figure, which evidently has served as original of their own description, and of copies introduced in illustrative works upon that order of animals. FAM.

Ground colour dark brown or black ; a band on the side of the neck from the shoulder to the eye, 5 to 7 distant, transversal series of separate rings, between which numerous spots or interrupted transversal lines, all yellow or yellowish white; the outside of the limbs and the tail spotted, the latter indistinctly banded with yellow. Beneath yellow, the throat with indistinct transversal black bands and minute spots; the sides of the body and limbs in some individuals with large blackish dentilations. HABIT.-Malayan Peninsula, Pinang.

Philippine and Molucca Islands, Amboina, Java, Bengal. This species is very numerous both in hilly and marshy localities. It is commonly during the day observed in the branches of trees overhanging rivers, preying upon birds and their eggs, and smaller lizards, and when disturbed, it throws itself from a considerable height into the water. When attacked on level ground, it attempts its escape by running, if possible towards the water. Its quickness however is not so great as to prevent a man from overtaking it, when it will courageously defend itself with teeth and claws and by strokes of the tail. The

lowest casts of Hindoos capture these lizards commonly by digging them
out of their burrows on the banks of rivers, for the sake of their flesh,
which by these people is greatly relished.-Some individuals attain to
nearly 7 feet in length, but the majority are smaller. A female examin-
ed was of the following dimensions :
