Desmption of species. — (From No. 165, E. H. Taylor collec- 

 tion ; collected at Bunawan, Agusan, Mindanao, September 29, 

 1912, by E. H. Taylor.) (Adult female.) Head short and deep ; 

 rostral very narrow, nearly twice as high as wide, forming its 

 longest suture with nasal, just visible from above ; sutures v/ith 

 internasals smallest ; internasals twice as broad as long, in contact 

 with highest loreal, forming its shortest suture with it ; sutures 

 with prefrontals and nasals subequal ; prefrontals not as wide as 

 internasals, but longer and larger ; prefrontal suture shorter than 

 that between internasals ; frontal very large, one and two-thirds 

 times to twice as long as broad, narrowed in the middle, longer 

 than parietals, and much longer than its distance from end of 

 snout, not twice as wide as supraoculars, in contact with upper 

 preocular ; parietals but little longer than wide, somewhat broken 

 up behind, followed by several, somewhat enlarged, occipital 

 shields ; nasal single, in contact with 2 labials and 3 loreals ; latter 

 superimposed, upper nearly square, largest, lower longest, not 

 entering eye, in contact with 2 labials ; 2 preoculars, upper 

 largest; 4 suboculars (3 on left side) in a row, continuous with 

 preoculars ; no postoculars ; supraoculars elongate, extending 

 above and behind eye, nearly half surrounding it ; temporals 

 3 -f 8 ; 9 upper labials, none entering eye ; 12 lower labials ; men- 

 tal small with first 2 pairs of labials in contact behind it; the 

 usual chin shields are replaced by 3 unequal pairs of broad 

 plates, filling all the space between labials and first ventrals ; the 

 usual groove is missing on chin ; eye very large, equal or very 

 nearly equal to its distance from end of snout, greater than its 

 distance from mouth ; head short, narrow, and very thick, distinct 

 from neck, with 2 rather prominent occipital knobs ; scales in 13 

 rows, the median row enlarged, and an enlarged outer row; tail 

 prehensile, sharply pointed ; body much compressed ; ventrals, 

 156; anal single; subcaudals, 104; tail narrows very greatly 

 immediately behind anus.
