ANDERSON ON INDIAN REPTILES. 177 From these observations it would appear that the normal number of the postoculars of this species is 3 + 3, and that the temporals vary between 1 + 2 + 3. No. Length.

Darjeeling, 3500 to 5000 feet, common. TROPIDONOTUS MACROPHTHALMUS, Gthr. I.e. p. 262. Three specimens, resembling Giinther's figure and description in every respect. One of the adults, however, is a reddish brown with the dorsal series of spots pale reddish brown. In the young the anterior third has a dorsal and two lateral series of spots placed alternately to each other and connected by narrow lines enclosing-scales with white margins ; its head is slightly green above ; and it has the arrow-shaped mark on the neck ; and the posterior third of the body is coloured as in the adults.

I have since had three other specimens of this well-marked species under m y observation; and in one there are only two postoculars on one side, while there are three on the other; so that we may expect to meet specimens with two postoculars. Another has only seven upper labials on one side and eight on the other ; and this abnormality is evidently due to the union of the third and fourth, for the third is much larger than in normal heads. In a young specimen of this set there is a large black arrow-shaped mark on the nape of the neck, and not visible on the two other adult specimens. The yellow collar forms a narrow line before this. In the young the lateral spots are entirely black, round, and surrounded by a well-defined, pale, circular area, which is connected with the corresponding area round the spot on the opposite side by a pale transverse band. This species does not appear to be uncommon at Darjeeling. TROPIDONOTUS SUBMINIATUS, Reinw. ; Gthr. I c. p. 265. In two specimens which I refer to this species there are nine upper * Tail imperfect.
