Species of Snakes from Sarawak. 229 



Calamaria Hosei, sp. n. 



Moderately slender in habit ; head broad, depressed ; eye 

 very small. Scales in 13 rows ; ventrals 138 ; subcaudals 19. 

 Upper labials 5. A minute prseocular in the anteroinferior 

 corner of the orbit, and a very small postocuiar. The vertical 

 shield is very broad, at least four times as broad as the supra- 

 ocular. The symphysial is in direct contact with the men- 

 talia. Two transverse rows of scales before the first ventral 

 scute. Upper parts pinkish, with black cross-bars, which are 

 narrower than the interspaces between them and contracted on 

 the sides ; there are eighteen of these cross-bars on the trunk 

 and three on the tail. The scales within the pink parts of 

 the body are bordered and speckled with blackish. Head 

 brownish above, this colour extending downwards on the 

 sides in the form of two ill-defined oblique bands. Tail with 

 a blackish longitudinal stripe along each series of scales. 

 Lower parts white, with a few scattered blackish spots ; sub- 

 caudals blackish. 



One specimen, 14 inches long (of which the tail takes 

 1^ inch), was discovered by Mr. Hose on the Entoyut River. 



Geophis albonuchalis, sp. n. 



Head narrow, snout pointed, body moderately stout, tail 

 tapered ; eye very small. Scales in 15 rows, without apical 

 groove. Ventrals 141 ; anal entire ; subcaudals 43. Ante- 

 rior frontals triangular, small, only one fourth the size of 

 posterior, which enter the orbit. Vertical very large and 

 broad, broader than long, reaching from one orbital margin 

 across to the other, and pressing back the supraocular to the 

 postero-superior angle of the orbit. Occipitals as long as the 

 anterior shields together, and forming a long suture with the 

 filth upper labial. Two nasals. Loreal and anteocular con- 

 fluent into one long shield. A minute postocuiar. Upper 

 labials six, of which the third and fourth enter the orbit. 

 Symphysial in direct contact with the mentalia, which are 

 considerably longer than the post-mentalia. Six lower labials, 

 the fifth long and narrow. 



Deep black, with a broad pure white collar, which covers 

 half of the occipitals and the neck. 



One specimen, 9^ inches long (of which the tail takes
