30. Lygosoma klo.ssi, sp. n. (PI. XXTX. figs. 3, 3 a.) 



Section Emoa. Habit lacertiform ; the distance between the end of the snout and 



the fore limb is contained once and one-fourth to once and one-third in the distance 



between axilla and groin. Snout rather elongate, obtusely acuminate. Lower eyelid 



with an undivided transparent disk. Nostril pierced between three shields — a nasal, 



a postnasal, and a supranasal ; frontonasal much broader than long, forming a broad 



suture with the rostral and a narrower one with the frontal ; latter a little longer than 



the frontoparietal, in contact with the first and second supraoculars ; four supraoculars ; 



seven supraciliaries ; frontoparietals and interparietal fused to a single large shield ; 



parietals forming a long suture behind the latter; a pair of nuchals and a pair of 



temporals border the parietals ; six or seven labials anterior to the large subocular. 



Ear-opening oval, larger than the transparent palpebral disk, with one or two small 



projecting lobules anteriorly. 30 or 32 scales round the middle of the body, dorsals 



with five or seven feeble keels ; dorsal scales largest, laterals smallest. Marginal 



pvEeanals scarcely enlarged. The hind limb reaches the axil. Digits rather elongate, 



feebly compressed ; subdigital lamellae smooth, 40 to 42 under the fourth toe. Brown 



above, strongly iridescent, Avith black spots, with or without scattered whitish spots 



occupying a whole scale ; a black band on each side from the eye to the shoulder ; 



lower parts greenish, with scattered black dots.

Two specimens from Camp III, Utakwa R., 2500 ft. (Wollaston Exped.). 



Apart from the coloration this species is distinguished from L. ci/aminim, L. baudinii, 

 and other allies by the number (6 or 7) of anterior upper labial shields and by the 

 numerous feeble keels on the dorsal scales.
