probably to the fact that it is younger. The rostral is a little 

 more exposed above, and the postoculars are fused into one 

 scale. The temporal formula is 1 + 2 + 2. The color above is 

 a dark brown with 16 white bands from head to tail; a brown 

 streak, partially following the parietal suture, divides the occip- 

 ital band.

The Palawan form agrees quite well with the specimens from 

 Asia and Java. Boulenger gives the variation in ventrals as 

 198 to 227; in subcaudals, 61 to 89. He also mentions the fol- 

 lowing variations : Sometimes the sixth labial enters the eye, 

 making 4 in all ; sometimes the loreal does not enter the eye ; the 

 anal is rarely entire. The two specimens above recorded are 

 the first and, I believe, the only records for the Philippines. 



Genus HAPLONODON Griffin 



Haplonodon Griffin, Philip. Journ. Sci. § D 5 (1910) 211; § D 6 

 (1911) 258. 



"Maxillary teeth in two series, separated by a short inter- 

 space; the posterior teeth of each series largest, 14 or 15 in 

 all. Anterior end of maxilla bent slightly inward. 



"Anterior mandibular teeth enlarging to the fourth, followed 

 by smaller teeth of equal size. Head distinct from neck. Eye 

 moderate, pupil vertically elliptic. Body slender, slightly com- 

 pressed; tail long. Scales smooth, in 17 longitudinal rows, 

 without apical pits; subcaudals in two rows." (Griffi)).) 



Only a single species known. Exclusively a Philippine form.
