femur, but not a trace of fold on sides of body or tail; tail not longer 

 than body (without head), narrow, slightly depressed, not more 

 flattened underneath than above; body and extremities above and 

 below covered with minute granules, those on the underside of the 

 tail slightly larger; rostral broad, rectangular, with a median triangu- 

 lar process above, in touch with a small median intemasal between 

 two wide supranasals; nostril between rostral, first supralabial, one 

 small postnasal and two supranasals, the anterior of which are very 

 wide and nearly meeting behind the rostral; 15 upper (14 on right 

 side) and 14 lower labials; mental small, not distinguishable by size 

 or shape from the other labials; no chin-shields, but the throat gran- 

 ules increase gradually in size toward the labials; a transverse group 

 of somewhat enlarged granules a short distance in front of the vent, 

 the posterior row bearing an uninterrupted series of 16 pores; tail 

 above slightly amiulate, each amndus marked posteriorly on the 

 side by a slightly enlarged spine-like scale. Color (in alcohol) "above 

 dull russet clouded with indistinct dusky markings wliich are more 

 or less longitudinal; underside whitish, slightly washed with russet.

Remarks. — Besides the one described above, Mr. McGregor cap- 

 tured in the same place a very young specimen which in all essentials 

 agrees with it. The tail is complete and equals the distance between 

 the head and the vent. The chief difi'erence in the scutellation 

 consists in the large anterior supranasals being abbreviated by the 

 separation of a small scale at the inner end, there being thus three 

 internasals in touch with the rostral instead of one. The color is 

 also essentially the same, but the russet color of the upper side, 

 instead of gradually fading into a pale wash on the abdomen, invades 

 the latter in the form of well-defined, but narrow, transverse, and 

 somewhat wavy lines. 



The present species seems to differ from the type of the genus 

 Lwperosaurus cumingii chiefly in the differently shaped tail and the 

 total absence of a fold along the sides of the body. The latter is not 

 specifically mentioned by Boulenger in his description (Cat. Liz. Brit. 

 Mus., I, p. 181), but it is plainly shown in the figure (Plate XV, fig. 2).
