SECOND YAEKAND MISSION. 
but not quite touching. Nostrils rather in front. Prseocular and ocular about equal, neither 
of them as large as the nasal, anterior margin of prseocular very convex, that of ocular straight 
and vertical, except on the top of the head, where it is curved back. Prsefrontal, postfrontal, 
supraocular, and interparietal scarcely exceeding the back scales in size; the parietals are con¬ 
siderably broader. Upper labials four, the first very small, in contact with the rostral and 
fronto-nasal; the second below the fronto-nasal and nasal, and just reaching the prseocular; 
the third between the prseocular and ocular, but not rising much on the side of the head; 
the fourth, which is considerably the largest, beneath the ocular and extending some distance 
back beyond it. Eyes quite invisible. 
This differs from the description of T. porrectus in being rather less slender, in having 
fewer longitudinal rows of scales, and only eight instead of eleven to twelve rows round 
the tail, and, to judge by Dr. Stolizcka’s figure, in the smaller size of the frentals, inter- 
parietals, and supraoculars.

This specimen, which is young, bemg only 24'5 inches long, has the scales absolutely 
smooth throughout, and a second prseocular, formed of a detached portion of the supra- 
labial series, between the third and fourth labials. A similar specimen has been described 
by Stoliezka, loc. cit., from the North-Western Himalayas. Ventrals 227, suhcaudals in 79 
pairs.

These specimens do not differ from the ordmary Indian form. Kashmir must, I should 
think, be at the extremity of this snake’s range to the north-west.

The spots on the head and back are larger than in Persian specimens, and somewhat 
resemble those of Z. diadema^ whilst the dark band along the upper part of the tail has a
