Rema7-ks. — The type was obtained on Bubuan, Tapian Group, 

 in Sulu Archipelago. It was found in a rotten log only 

 about 4 meters from the high-tide mark on the beach. 

 Much effort was made to obtain other specimens on this island, 

 but none was found. This species seems to be most closely re- 

 lated to Typhlops multilineatus and T. olivaceus. From the 

 former the following differences are evident: The rostral is 

 shorter, the nasal completely divided, the diameter of body con- 

 tained in total length forty times (in multilineatus fifty to 

 sixty times), twenty -two instead of twenty scales around middle 

 of body; the prefrontal larger, the frontal smaller; the color is 

 not arranged in longitudinal lines. From T. olivaceus it differs 

 in the complete division of the nasal,. the preocular much nar- 

 rower than the ocular, the rostral barely half the width of 

 the head; the color i.« also different. 



Python reticulatus Schneider. 



No specimen taken. Reported as being present on Tawitawi, 

 Basilan, and Jolo, where they are said to be fairly common. 



Xenopeltis unicolor Reinwardt. 



A mutilated specimen of what is presumably this species 

 was brought to me by a Samal, in Bongao. Most of the head is 

 missing, but the following body characters agree largely with 

 specimens of this rare snake from Palawan. Ventrals, 168; 

 anal divided ; subcaudals, 28 ; scale rows, 15 ; three lower labials 

 in contact with the anterior chin-shields. Body somewhat flat- 

 tened, deep blue-black above, the three lateral rows of scales 

 white-edged; outmost row white, with dim dark dots; ventrals 

 white ; a few scattered dark spots on the posterior part of body. 

 Underside of tail black, the scales with white edges. Length,
