SYSTEMATIC ACCOUNT OF THE SPECIES. 253 



Description: — M. C. Z. 7,337. Jamaica: Constant Springs near Kingston, 

 1909. Thomas Barbour. 



Snout rather short and broad, its length not quite twice the diameter of the 

 eye; eye slightly nearer tip of snout than ear; rostral large with median groove; 

 nostril between rostral, two large supranasals and several tiny scales which 

 occlude it from the first supralabial ; a group of small scales separate the supra- 

 nasals of the two sides; superciliary spine large and prominent; four large 

 supralabials, the fifth very small, under eye; head above with granular non- 

 imbricating scales, not enlarged on the snout; scales of back large, rough, tecti- 

 form, imbricating about five or six equalling distance from tip of snout to centre 

 of eye; no middorsal granular zone; mental large, followed by two enlarged 

 postmentals, chin-shields and gulars small, juxtaposed; scales of belly imbricate, 

 smooth, roundish, smaller than dorsals; scales of limb enlarged, keeled and 

 imbricate; scale of tail elongate, strongly overlapping forming definite whorls. 



Dimensions: — Tip of snout to vent 40 mm. 



Vent to tip of tail 35 mm. 



Greatest width of head 8 mm. 



Tip of snout to ear 10 mm. 



Fore leg 12 mm. 



Hind leg 14 mm. 



Remarks: — One of the peculiarities of this species is that it has the same 

 tender paper-like skin which is seen in AristeUiger and Thecadactylus. Indi- 

 viduals are rare and the three I found were under rocks in a rather xerophytic 

 environment. Dr. Clark found his at Montego Bay, under stones also. This 

 is the largest and most striking member of the genus. It is not only long but 

 stockily-built and can be distinguished at once by the very large tectiform dorsals 

 and the absence of a dorsal granular zone which the other large and big-scaled 

 species all have.
