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, rounded, smooth, 
imbricate, with only a very faintly defined series of enlarged scales. 
Colour:— Rich dark mahogany-brown specked with darker, a light streak 
around the head and a series of light 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 4mm. 
Tip of snout to ear 5.5 mm. 
Fore limb 6.5 mm. 
Hind limb 8.5 mm. 
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- 
known form.

Sphaerodactylus buergeri Werner, Verh. Zool.-bot. ges. Wien, 1900, 50, p. 264. 
Type-locality:— Port of Spain, Trinidad. 
Type:— Vienna Museum. Otto Buerger. 1897. 
Distribution:— Trinidad. 
Diagnosis:— Medium size, with rhombic, imbricate, keeled scales; with 
broad dark bands on back and sides, the former of which forks to each supra- 
ocular region. 
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.”
