This species, better known to English Dealers under the name of The Lace Lizard, is peculiar in having the two series of the scales, placed on the upper part of the centre of the tail, raised into a biserrated ridge, and in the outer toe, or rather thumb, of the hinder-foot being long, and reaching to the penultimate distal joint of the first or longest toe; the claws are compressed, sharp.
Genus PHELSUMA.

Gray.
Pedes quatuor, digitis fere aequalibus, totis lobatis, muticis; poris femoralibus distinctis.
Caput et truncus supra tesserulis minutis, infra squamis minimis, tecti.
This genus, which appears to be confined to the Isle of France, differs from the rest of the Geckonidae, by the toes being dilated the whole length, and entirely clawless, and covered beneath with transverse scales; by the thumb being very small and indistinct, and by the thighs being furnished with a series of minute pores.
