Colo7- m life. — ^^Above and below dark (sometimes purplish) 

 brown, each scale having a darker area with the edges somewhat 

 lighter ; end of snout grayish. 



Remarks. — Several specimens of this species were taken on 

 the eastern coast of Mindoro at Sumagui, on the Liddell Planta- 

 tion ; ten specimens were taken later at Calapan, on the northern 

 coast. They were found burrowing under logs and in rotting 

 wood. Very little variation is evident; most of the specimens 

 have 22 instead of 24 scale rows; one specimen has only five 

 upper labials, the third entering the orbit. The females give 

 birth to two young. Embryos taken from one female measured 

 56 and 54 millimeters; they seem almost entirely developed. 



This species is closely related to Brachymeles honitse, but 

 differs from it in the following characters: The leg stumps are 

 even more reduced, the prefontals and frontoparietals are smal- 

 ler, nuchals are present, the mental is much smaller, and the 

 postmental is in contact with two instead of one labial, the second 

 pair of divided chin shields are broader than the first pair and 

 are separated by a single scale. 



I take pleasure in naming this species for Mr. Clark Burks, 

 who assisted in making collections in western Mindoro.
