148 MR. G. A. BOTJLENGER ON REPFILES AND [Feb. 15, 



rostral and a still broader one with the frontal ; pr?efrontals very 

 small and widely separated ; frontal short, in contact with the first 

 supraocular only, followed by a long and narrow single frontoparietal 

 resembling a second frontal ', angular posteriorly and in contact 

 with the interparietal; latter in the middle between four small 

 parietals, the posterior pair of which are in contact behind ; four 

 supraoculars, first in contact with the frontal and the frontoparietal, 

 second and third in contact with the frontoparietal ; seven supra- 

 ciliaries ; fourth upper labial below the centre of the eye. Ear- 

 opening small, horizontally oval, without projecting lobules. 24 

 scales round the middle of the body, subequal; dorsals rather strongly, 

 laterals feebly tri- or quinquecarinate. Praeanal scales not enlarged. 

 Limbs widely separated when adpressed ; the length of the hind 

 limb equals the distance between the fore limb and the nostril. 

 Digits short, cylindrical : subdigital lamellae smooth, 10 under the 

 fourth toe. Tail a little longer than head and body. Reddish 

 brown above, dark brown on the sides ; a black lateral band, com- 

 mencing from the eye ; sides with fine whitish shafts ; belly dirty 

 white, spotted with dark brown ; lower surfaces of tail plumbeous 

 grey, spotted with black.

Scales in fifteen rows, without apical groove, with a very feeble 

 keel along their anterior half. Rostral rather broader than deep ; 

 nostril between two nasals ; proefrontals about twice as long as 

 interuasals ; frontal much longer than broad, as long as or slightly 

 longer than iuternasals and prsefrontals together ; loreal at least 

 twice as long as deep ; one prte- and two postoculars ; eight upper 

 labials, fourth and fifth entering the eye, seventh largest ; temporals 

 1 -f 2 ; five lower labials in contact with gulars. Ventrals 187-192 ; 

 anal divided ; subcaudals 72-82. Olive above, the scales lighter in 

 the centre ; the lower scale on each side yellowish, margined with 

 olive or black; in some specimens four rather indistinct dark brown 



' The very singular shape of this shield misled Hallowell as to the homo- 

 logies of the head-shields of this Lizard. Therefore his internasal = fronto- 

 nasal ; froutouasal = frontal ; frontal = frontoparietal ; iiitej-parieto-fronto- 

 parietal = interparietal ; frontoparietals = anterior parietals.
