Description of species. — (From No. 88, Bureau of Science 

 collection; collected at Iwahig, Palawan, March, 1909, by W. 

 Schultze.) (Adult male.) Anterior palatine and mandibular 

 teeth very strongly enlarged; head large, distinct from neck; 

 rostral scarcely visible above, broader than deep, forming its 

 longest suture with nasal, its shortest with first labial ; inter- 

 nasals broader than long, curving downward on sides, rather 

 narrowed in front, their mutual suture little more than half 

 that between prefrontals ; latter very much larger than inter- 

 nasals, forming their shortest sutures with nasals and supra- 

 oculars, broader than long, a little shorter than frontal; latter 

 about five-sixths as wide as long, shorter than its distance from 

 rostral, little wider than supraoculars ; parietals very little longer 

 than wide, in contact with upper postocular, nasal divided, nos- 

 tril large ; loreal present, longer than high ; preocular single, 

 very high, visible above, touching only fourth labial below ; 2

 pits, in 23 rows around body, the outer ventral row strongly 

 enlarged ; ventrals 268 ; anal single ; subcaudals 149 ; eye very 

 large, its diameter about equal to its distance from nostril ;
