widely distributed over southeastern Asia, Malay Archipelago, 

 and Formosa. The specimens are usually taken in forests, fre- 

 quently under logs and trash, and quite as often while crawl- 

 ing about in the open, or on small bushes.

"Maxillary teeth 20, subequal, the last two or three a little 

 enlarged and grooved ; anterior mandibular teeth enlarged. Head 

 elongate, distinct from neck, with distinct canthus rostralis; 

 eye rather large, with horizontal pupil; nasal entire; frontal 

 narrow, bell-shaped. Body slender, compressed; scales smooth, 

 oblique, with apical pits, in 1.5 rows ; ventrals with suture-like 

 lateral keel and a notch on each side corresponding to the keel. 

 Tail long; .subcaudals in two rows, keeled and notched like the 

 ventrals." (Boulenger.) 



Two species are known, D)-yophiops rubescens Gray, and D. 

 philippina Boulenger, only the latter occurring in the Philip- 

 pines. This species is presumably confined to the northern 

 part of the Philippines. It difi'ers from the former species in 

 the absence of a loreal scale.
