Calotes ophiomachus. Specifically identical with an example 

 from the Nicobars, noticed J. A. S. XV, 376 :* but a nearly affined 

 Calotes from Cherra Punji (presented by Mr. Frith) differs in having 

 the head much flatter, the nuchal spines less laterally compressed or 

 widely flattened and more rigid, being scarcely at all expanded on 

 their terminal half, and in having a well marked second sincipital crest 

 above the ear, shewing eight spines, the first three of which are short 

 and the fifth longest : there is also no black stripe through the eye. — 

 C. platyceps, nobis, n. s. 



C. versicolor. Specimens very strongly mottled, but apparently 

 identical with the extremely common and only species of this genus 

 we know of in Lower Bengal. 



C. Rouxi 1 This species is probably distinct and undescribed ; 

 but as Dr. Kelaart has forwarded a series of Ceylon reptiles to Dr. 

 Andrew Smith in England, we decline naming it at present. Crest of 

 elevated flattened spines much longer than in C. versicolor, con- 

 tinued along the entire back and over the base of tail ; two isolated 

 spines, one before the other, above the ears ; oblique plait of neck, 

 before the shoulders, well marked in adults; a very slight /anon, or 

 indication of one, on the throat ; lateral scales fully twice as large as 

 the abdominal ; longest hind-toe reaching to the ear ; tail f of the total 

 length : colour fulvous-green, reddening on the throat of two specimens 

 under examination ; tail (in the faded specimens) chiefly albescent ; 

 radiating dark marks on the eyelids, as in C. versicolor. 



C. MYSTACEus.f Nuchal and dorsal crest diminishing gradually 

 to base of tail ; two separate groups of 3 or 4 spines each above each 

 ear ; lateral scales not much larger than the abdominal ; a very dis- 

 tinct well marked fanon in adults; tail f of the total length; longest 



* The supposed Calotes mystaceus of the Nicobars, loc. cit., is a Sale a of 

 Mr. Gray, except that the back is crested throughout ; and a very similar species 

 in the museum, save that the throat-skin is lax and forms a sort of fanon, was 

 procured, we believe at Mirzapore, by the late Major Wroughton. 



f Identical in species with examples since received from Rangoon.
