back and sides very small, granular, without trace of a keel ; ventrals 

 smooth. Digits shorter than in the other species. Tail much 

 depressed, as broad as the pelvic region, with extremely strongly 

 marked segments; these composed of seven or eight transverse rows 

 of scales above, of five or six beneath ; all the scales of the tail 

 perfectly smooth, those on the lower surface larger, subequal, without 

 median transversely dilated scales. Praeanal pores forming a short 

 angular series in front of the vent, six on each side. Upper parts 

 blackish olive, lower bluish grey ; lips and throat whitish in 

 specimen a.

5. Phelsuma guentheri. 



A large species with the physiognomy of P. madagagcariense. 

 Snout nearly twice as long as the distance between the orbit and 

 the ear-opening. Rostral with median cleft above ; nostril pierced 

 above the rostral and the first labial, the suture between those 

 two plates entering its lower border ; eleven to fourteen upper and 

 nine or ten lower labials ; chin-shields rather small, three or 

 four on each side, decreasing in size from inner to outer, well 

 distinguished from the gular granules, which are minute ; a single 

 scale between the anterior nasals. Ear-opening oval, about one 

 third the diameter of the orbit. All the scales of the back and sides 

 very small, granular, without trace of a keel ; ventrals smooth. 

 Tail depressed, much narrower than the body, divided into distinct 

 segments, each of which contains six transverse rows of scales on the 

 side, eight or nine on the upper surface; lower surface with enlarged 

 scales, not dilated transversely ; all the caudal scales perfectly 

 smooth. Femoral pores forming a long series, as in P. madagas- 

 cariense, composed of forty-five or forty-six pores altogether. Upper 

 surfaces uniform grey (epidermis lost); lower surfaces whitish.
