contact with the postocular, the occipital two lower temporals and 

 three small temporal scales behind. Shields of head as a Hydrophis 

 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 

 onthesiL. Belly uniformly yellow. Tail dark with yellow stripes. 



The specimen was jumbled among a lot of E.ihydrmce, probably 

 from the Sandheads. -. T , 



Its nearest ally is H. Stolcesn, but it seems a new species and I have, 

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

 gist to whom Indian Naturalists 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 PO^ocular : 

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

 twosmall plates belowthem; 1st upper labial very «™f'>?£*™$£tiiL 

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

 lower ^ supernumerary plate wedged in behind it, and above it and he 

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

 temporal. Two pairs of chin-plates approximate irregularly ^omboidal 

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

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

 yellow. Back barred with 63 dark lozenges combined mfamt bars

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



This specimen was labelled II. nicjvocinda, Daud. with which it has 

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

 distin o-uish it from any snake described by Gimther. 



"Bay of Bengal" is the only note attached to it, but I think I recog- 

 nize it as one of many (and almost the only one remaining) Presented 

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

 fishing stakes. 



H. viperina, Schmidt. 



a. young. Eangoon. 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. 



PELAMIS, Daudin (sp.) 



P. bicolor, Schneid. 



a. fine adult. Nicobars. M. Busch. 



(var y sinuata.)
