Head small, short ; snout obtusely subtriangular, short, measuring 

 slightly more than the distance between the eye and the ear-opening, 

 and twice the diameter of the orbit, with vertical loreal region and 

 obtuse canthus rostralis ; no trace of a concavity on the upper 

 surface of the head ; eye very small, with distinct circular lid ; ear- 

 opening very small, oval, horizontal. Body and limbs moderate, 

 slightly depressed. Head covered with granular scales posteriorly, 

 with polygonal, flat, or more or less convex, considerably larger 

 scales on the snout ; rostral about twice as broad as high, with 

 distinct median cleft superiorly ; nostril pierced between the first 

 upper labial and three or four small nasals ; eleven or twelve upper 

 and ten or eleven lower labials ; mental twice as broad as high 

 anteriorly, narrowed posteriorly; the mental and labials followed 

 by very small chin-shields gradually passing into the minute granules 

 of the throat. Upper surfaces covered with small granules; lower 

 surfaces with very small, slightly imbricated scales. Male with a 

 large median patch of prseanal pores and two series of femoral 

 pores. Tail long, cylindrical, covered with very small subequal 

 juxtaposed scales. The coloration varies considerably : the speci- 

 mens in the collection may be referred to the following varieties of 

 coloration : — 



A. (N. elegans. Gray.) Brownish, purplish, or dark olive above, 

 yellow beneath ; a streak on each side of the crown, another on the 

 lower lip, and generally also one from axilla to groin, and large 

 paired spots on the back and tail, yeUow, black-margined.- (Specs. 

 a, m, n, o, q, r, s, cc, z, (i, y, S.) 



B. {if. punctatus, Gray.) Green, upper parts minutely dotted 

 with black ; hands and feet yeUow inferiorly. (Specs, c, a.) 



C. {N. grayi. Bell.) Uniform green, lighter beneath ; hands and 

 feet yellow inferiorly. (Specs, d, f, g, h, i, k, I.) 



D. {N. sulphureus, Buller.) Uniform lemon-coloured. (Specs.

E. Pink above, yellow beneath, uniform. (Spec, e.) 



F. Green above, yellow beneath, uniform. (Specs, t, w.) 



G. Green, lighter beneath, with a few distant, paired yellow 

 spots on the back, and a rather indistinct yellow streak from axilla 

 to groin ; hands and feet yellow. (Specs, e, u.)
