Show 18/1.] DR. J. ANDERSON ON INDIAN REPTILES. 161 shield behind the chin in the decided way of the type. All these specimens have the round ear of P. andamanense. Blyth does not allude to the compression of the root of the tail from above downwards, or to its being thrown into folds at nearly regular intervals (at any of which it is very liable to fracture), or to the verticillate distribution of the small tubercular-looking scales, or to the enlarged subcaudals. Upper labials ten, lower labials seven to nine. Length of largest specimen 5 | inches, of which the tail measures 3 inches. Hab. Andamans. GYMNODACTYLUS FASCIOLATUS, Blyth ; Gthr. I. c. p. 116. Naultinus fasciolatus, Blyth, Journ. As. Soc. Beng. xxix. p. 114. Body finely granular, with numerous enlarged trihedral tubercles. Granules on tail verticillately arranged, and tubercles disposed in rings. A series of enlarged subcaudals. Tail slightly flattened from above downwards, cylindrical at the base. Scales in the middle of the belly in thirty-six longitudinal series. Nostril formed by the rostral anteriorly, by the first labial, by the nasal and a small shield between it and the labial; rostral notched and grooved, with a small plate between the two nasals. Twelve upper and eleven lower labials. Mental shield partially wedged in between two large pentagonal chin-shields, which have a small quadrangular shield on the concave external half of their lateral margins. Three rows of enlarged scales below the lower labials. Claws non-retractile ; five fingers and toes, with from four to nine transverse plates on the basal depressed portion. A slight fold of skin along the side, corresponding to the line of union of the belly- scaled and dorsal granuled portions of the body (probably a post-mortem appearance as in Puellula, Blyth). A n area of enlarged praeanal scales. The femoral pores, five or six on each side, extend outwards in a line with the commencement of the thigh. A dark brown band, edged behind with white, from the eye to the occiput, where it meets its fellow of the opposite side. A brown similarly white-edged band on the nape, with seven cross bands on the body ; thirteen on the tail, the white edging disappearing posteriorly. This species has the toes and claws of Gymnodactylus, and its femoral pores distributed outwards in the direction of the thighs. Mr. Blyth considered this species closely allied to the following, from which it differs in the smaller size of the belly-scales and in the greater number of femoral pores. Hab. Subathoo. GYMNODACTYLUS VARIEGATUS, Blyth ; Gthr. I. c. p. 116. Naultinus variegatus, Blyth, Journ. As. Soc. Beng. 1859, xxviii. p. 279. Body granular, covered with numerous large trihedral tubercles. Tail cylindrical, the granules arranged in verticils, and the tubercles in rings. A series of enlarged subcaudals. Twenty-six longitudinal rows of rather elongated leaf-like scales on the middle of the belly. PROC. ZOOL. Soc-1871, No. XL |
