xn,D, 6 Taylor: Snakes and Lizards of Negros 377 



The foreleg reaches forward to the nostril; the hind leg fails 

 to reach the axilla by a considerable distance. 



Variation. — The cotype varies in not having the frontal nar- 

 rowed so quickly as the type and the interparietal shorter. 



Remarks. — This form differs from L. pulchellum in the larger 

 number of supra-oculars ; the shape of the head; the shorter 

 hind leg, which does not reach the axilla; the frontal touches 

 four instead of three supra-oculars; the interparietal is very 

 much smaller and narrower than the frontal; two scale rows 

 less around the body. It obviously grows to a larger size. I 

 have ten typical specimens of L. pulchellum for comparison. 

 They are invariably shorter, the heads narrower, the median 

 streak brillant golden yellow, and the tail brownish yellow with 

 the markings almost totally disappearing. 



Only two specimens of the present subspecies were taken, 

 these in the same immediate locality on Mount Canlaon.

Type. — No. 894, E. H. T. collection. Canlaon Volcano, Ne-

Description. — Rostral large, covering the end of the conical 

 snout, forming a broad suture with the frontonasal, about equal 

 to that with the nasals; frontonasal very large, convex ante- 

 riorly and concave behind, forming its largest suture with 

 frontal; latter rather triangular in shape, longer than broad, 

 anterior part rounding, not as wide as supra-ocular region; 

 frontoparietals fused into a single large scale, which is dis- 

 tinctly wider than supra-ocular region, in contact with three 

 supra-oculars; interparietal as wide as frontal, but shorter; 

 parietals elongate, diagonal, more than twice as long as wide, 

 joined behind the interparietal, in contact anteriorly with two 

 very small postoculars ; three or four pairs of enlarged nuchals ; 

 nostril pierced in the middle of the single nasal, which is fol- 

 lowed by two f renals subequal in size, as high as the nasal ; two 

 superimposed preoculars; eight superciliaries, anterior largest; 

 four supra-oculars, two touching the frontal, second widest ; two 

 pairs of slightly enlarged postoculars and a row of scales above 

 the upper labials; a rather enlarged scale between fourth and 

 fifth upper labials; eight upper labials, fifth and sixth largest, 

 below the eye ; two greatly enlarged temporals with three or four 

 others not so large; auricular opening comparatively large, a 

 little more than half the diameter of eye ; tympanum distinct, not
