XII, D. 6 Taylor: Snakes and Lizai'ds of Negros 369 



prominence about the nostril ; anterior supranasal in contact with 

 first labial; between the nasals, immediately behind rostral, are 

 three rather enlarged, rounded scales, and a small, probably 

 anomalous, scale; 13 or 14 upper labials, last two very small; 

 angle of mouth without differentiated labial scales; two super- 

 imposed, enlarged scales behind postnasal, followed by a row 

 of irregularly enlarged scales bordering labials; 11 lower labials, 

 a row of small rounded scales bordering lower labials, those 

 touching mental smallest, two or three rows of smaller scales 

 bordering these ; scales on forehead tubercular, much larger than 

 those on body; ear opening small, its greatest diameter equal 

 to one third or one fourth the diameter of eye, nearer the eye 

 than the foreleg; eye large, pupil vertical; dorsal and lateral 

 scales tubercular, minute; ventrally, scales rounded, somewhat 

 imbricate, and larger. 



A long continuous line of 26 enlarged scales in preanal and 

 femoral region, the 9 median largest, in a somewhat curved 

 line, some of the scales apparently perforated with small pores. 

 It is probable that the 9 enlarged scales (not improbably the 

 entire 26) represent the number of pores in the male. A few 

 rows of enlarged scales behind this row in front of anus. Tail 

 much flattened, especially below, bordered on the sides by a 

 broad denticulate fringe, the annulations, scarcely distinguish- 

 able; scales below rounding and distinctly larger than those 

 above. Tip of tail regenerated; this has the fringed edge, but 

 the serrations are smaller and scales above and below are not 

 arranged regularly. Foreleg pressed forward reaches anterior 

 border of eye ; no distal joint on inner digits, others with clawed 

 distal joints rising from near the broadened extremity of digit ; 

 lamella on the broadened portion of digits divided by a median 

 groove ; strongly denticulate on outer edge ; these divided lamellse 

 followed by undivided scalelike lamellae, decreasing in width; 

 fourth toe with 8 or 9 lamellae, the first four divided; digits of 

 both limbs with webs, a slight web behind the hind leg. 



Color. — Above ashy gray to blackish brown on back and sides 

 of arms and tail ; snout darker, with a dark line passing through 

 the lower part of eye to shoulder; below lighter, flecked with 

 brown and with traces of yellow ; ventral side of tail more or less 

 reddish. The specimen was taken alive just at twilight. Then 

 it appeared to have a series of large well-defined markings above 

 and appeared yellow or white below. As it was necessary to 

 preserve the specimen at once, the colors of the living animal 

 were not observed by daylight.
