contact with the postocular, the occi]iital, two lower temporals and 

 three small temporal scales behind. Shields of head as a Ilijdroplils, 

 pustular. Each labial smooth in front, pustular behind. A small pair of 

 rounded chin shields separated by a groove. 



Color yellow, with dark lozenge bars on the back, becoming obsolete 

 on the sides. Belly uniformly yellow. Tail dark, with yellow stripes. 



The specimen was jumbled among a lot of Enhyclrlnce, probably 

 from the Sandheads. 



Its nearest all}- is H. Stohesil, but it seems a new species, and I have, 

 therefore, separated it under the name of the distinguished Herpetolo- 

 gist to whom Indiaii a^aturalists are so deeply indebted for his labors, 

 more especially in this confused Family. 



H. TRACHYCEPs, Theobald. 



Head conical, pointed or subtriangular, hardly longer than broad. 

 Body moderate, throat not slender. One ante-ocular, one postocular : 

 occipitals not broken up, entire. Six upper labials, the two last having 

 two small plates below them; 1st upper labial very small; 2nd very large ; 

 3rd enters the orbit with its posterior angle ; 4th under the orbit with a 

 lower supernumerar}^ plate wedged in behind it, and above it and the 

 6th; 5th touches postocular; 6th just touches postocular, and joins the 

 temporal. Two pairs of chin-j^lates approximate, irregularly rhomboidal. 

 Five lower labials, with a row above of marginal scales. Yentrals small 

 but distinct, smooth. Scales smooth on neck, in 32 rows. Color greenish 

 yellow. Back barred with 63 dark lozenges combined in faint bars 

 across the belly, on the anterior two-thirds of the body. Length 

 35 inches. 



a. Female and foetus. Mergui. W. Theobald, Jr. 



This specimen was lal^elled TI. nigrocincta, Daud. with which it has 

 no affinity. Its thick neck, remarkably conic head and ventral plates 

 distinguish it from any snake described by Giinther. 



'"' Day of BengaV is the only note attached to it, but I think I recog- 

 nize it a,s one of many (and almost the only one remaining) presented 

 by me from Mergui, where great numbers are daily captured in the 

 fishing; stakes.

a. young. Rangoon. Col. Nuthall. 



This specimen is in a bad shrivelled state, and is but doubtfully 

 referred to this species. The broad nasals posteriorly, broad anterior 

 ventral and coloration seem to agree with the type.
