scales granular, smooth ; no auricular denticulation ; lower 

 eyelid scaly ; subocular bordering the lip, between the fourth 

 and fifth upper labials; the three anterior pairs of cliin- 

 shields in contact. A feeble transverse gular fold, connecting 

 the ears ; collar distinct only at the sides. Dorsal scales 

 rhomboidal, subiinbricate, obtusely tectiform, 37 across the 

 middle of the body. Ventral plates in straight longitudinal 

 and transverse series, broader than long and subequal in 

 size, in 8 longitudinal and 26 transverse series. A large 

 pra?anal shield, bordered by two semicircles of scales. The 

 hind limb reaches halfway between the arm and the ear. 

 One series of large and two series of small subtibial shields. 

 12 femoral pores. Tail twice and a half the length of liead 

 and body ; upper caudal scales strongly keeled, lower smooth.

A single male specimen was obtained by Dr. Henry Martin 

 in February 1895 on rocks about a mile from the coast of 

 Obok, at the entrance of the Red Sea. It is now preserved 

 in the private collection of his son in Paris. 



It is interesting at the same time to record the occurrence of 

 a sea-snake, Hydrus pldturus, L., on the same coast. A 

 specimen was taken by fishermen in tiieir nets among rocks 

 near the coast and brought by them to Dr. Martin. No 

 sea-snake had as yet been reported from the lied Sea or the 

 Gulf of Aden.
