the mental followed by a small group of slightly enlarged scales passing quickly 

 into the small scales of the gular region; scales of chest and belly rounded, 

 smooth, imbricate; scales of tail smaller, irregularly arranged, rovmded, smooth, 

 imbricate, with only a very faintly defined series of enlarged scales. 



Colour: — Rich dark mahoganj'-brown specked with darker, a light streak 

 around the head and a series of Ught dots across the nape. 



Dimensions: — Total length ' 55 mm. 



Tip of snout to vent 29 mm. 



Vent to tip of tail 26 mm. 



Greatest width of head 4 mm. 



Tip of snout to ear 5 . 5 mm. 



Fore limb 6 . 5 nam. 



Hind limb 8 . 5 nmi. 



Remarks: — As I understand this species now the only specimens which I 

 have seen are a few taken by my friend C. T. Ramsden in the mountainous and 

 heavily forested region about Guantanamo, Cuba. It is a very rare and little-

Description (Translated) : — 



"Snout not quite twice as long as the diameter of the eye, somewhat longer than the distance of eye 

 from ear-opening, rounded anteriorly; ear-opening small, rounded, a little larger than one of the finger 

 disks. Rostral small, horseshoe-shaped with median groove. Nostril between rostral, first supralabial, 

 a supranasal and two postnasals. Five upper and five lower labials. Mental rather large, rounded 

 posteriorly, behind this polygonal shields which pass gradually into granules. Upper surfaces with 

 rhomboid, imbricate, keeled scales. Belly-scales much larger, smooth, similarly imbricating. The 

 scales of the under side of the tail, larger than the upper but no enlarged midrow. 



Colour: Upper surface light brown with somewhat darker side bands and a dark dorsal band, which 

 forks on the scapular region and sends a branch to each supraocular region. The two forked branches 

 and the temporal portion of the lateral stripe are edged with darker. The dorsal and lateral bands are 

 bordered with white on the tail as also on the back. Lower sides white, chin finely punctate with dark 

 spots, labials spotted with dark also."
