The sub-ocular (so-called) poison-gland is well developed, and is of 

 different consistence, to the naked eye, from the upper-lip gland. 



[One specimen caught alive at Saindak, 3000 feet, had a note- 

 worthy resemblance to an Echis carinata caught at the same time and 

 place.] 



25. Lytorhynchus maynardi, n. sp. Plate XIV. 



Snout pointed, moderately long. Rostral large ; viewed from 

 above it is anchor-shaped, the narrow beam of the anchor separating 

 the inter-nasals in about two-thirds of their extent, and the flukes of 

 the anchor embracing the nasals and first upper labials ; viewed from 

 below it is shaped like a pointed shovel, the posterior edge of the shovel 

 being conspicuously notched in the middle line to receive a leaf-like 

 process of the mental shield. Nostril a long, narrow, oblique chink 

 A pair of pree-frontals : frontal not quite three-fourths the length of the 

 distance between its anterior edge and the tip of the snout, rather more 

 than three-fourths the length of the parietals, anteriorly more than 

 twice the greatest breadth of the supra-oculars. Two loreals, the ante- 

 rior small. A ring of small scales surrounding the eye, of which two 

 are pra3-ocular, two post-ocular, and three subocular. Temporals 2 + 2, 

 the posterior hardly larger than the adjacent scales. Seven upper 

 labials, none of them entering the eye : ten lower labials, four of which 

 are in contact with the anterior chin-shields : mental trilobed, the 

 middle lobe fitting into the notch in the posterior edge of the rostral : 

 two pairs of chin-shields of about equal size. 



Scales smooth, in nineteen rows, not including the veutral scutes. 

 Ventrals rather acutely angulated on either side, about 192 : anal 

 divided : sub-caudals about 55. 



Colours in spirit : cream- colour with a faint pinkish flush on the 

 dorsal surface, and with a close series of large transversely-oblong 

 brownish-black patches or bars : along either side a series of small 

 lighter spots alternating with the dorsal bars : frontal and parietals 

 almost entirely blackish-brown, the colour being continued down the 

 nape, in the middle line, as a broad stripe : a narrow dark line through 

 the eye and temple. 



The largest perfect specimen measures at least fifteen inches, of 

 which the tail makes about 2J inches.
