214 GRIFFIN. 



Tlie specimen does upt agree exactly in all respects with the description 

 given by Boulenger in the Catalogue of the Snakes in the British Museum, 

 but it probably is one of this species. The stomach of this specimen con- 

 tains a large lizard (Calotes).

Trimerisurus halieus^ sp. nov. 



Subcaudals in two rows. Tail but slightly prehensile. Scales be- 

 tween eyes smooth, gular scales smooth. Upper surface of head flat and 

 depressed, snout with distinct canthus. First pair of lower labials in 

 contact behind the symphysial. Scales in 21 rows; ventrals 170-182, 

 anal entire, subcaudals 52-59 ; 10-13 scales between the supraoculars. 

 Supraocular narrow, often partially or completely broken up. Length of 

 eye not more than half the distance from the eye to the tip of the snout, 

 and in most specimens less. Dimensions of rostral equal, or the width 

 slightly more than the depth. Ifasal semidivided; internasals separated 

 by one, two or three scales; upper head scales of moderate size, fiat, 

 subimbricate ; two or three postoculars; a subocular, in contact with the 

 third and fourth lahials, separated from the fifth and sixth (and some- 

 times from the fourth) by one series of scales. 9-11 upper labials, 

 usually 10; the fifth to the last small; the first not fused with the 

 nasal; the second forming the anterior border of the loreal pit; the 

 third the largest, touching the subocular ; the fourth also large, its 

 upper portion occasionally separated as a distinct scale; temporal scales 

 smooth and large, scales of body distinctl}'- but not strongly keeled, 

 lateral rows and scales of tail smooth. 



The back and sides are dark blue to brownish-purple, either uniform 

 or crossed by irregular dull, reddish-brown bars. The ventral surface 

 is a light shade of the body color, generally bluish. The posterior border 

 of each ventral scale is more lightly colored, thus forming an alternating 

 series of light and dark transverse bands which correspond to the ventral 

 scales. There are no lateral stripes as in T. gramineus and T. flavo- 

 maculatus. The tail is colored like the body, never red.
