[B. 
Genus PHELSUMA, Gray. 
Pedes quatuor, digitis fere aequalibus, totis lobatis, muticis j poris 
femoralibus distinctis. 
Caput et truncus supra tesserulis minutis, infra squamis mini- 
mis, tecti. 
This genus, which appears to be confined to the Isle of 
France, differs from the rest of the Geckonidce, 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 fur-- 
nished with a series of minute pores. 
3. P. ORNATA, (n. s.) 
P. supra plumbea maculat fascidque rufd oruafat subtiis aU 
bida. 
Jeon. - 
Inhabits Isle of France. 
Head depressed, truncated in front, covered with minute 
ovate scales ; the front of the upper part lead-coloured, 
with a rather broad red band a little before the eyes, and a 
white crescent-shaped spot on each side immediately behind 
it, and then some obscure red shades just behind that; the 
back lead-coloured and blue, with six longitudinal series 
of irregular-sized red spots ; belly whitish ; tail rather 
longer than the body. Body one inch and five-eighths, head 
half an inch, tail two inches and a half long. 
This animal is very interesting, as being the second spe- 
cies of a genus recently established, which only consisted 
of P. cepeditty the Gecko cepedien of Peron; Cuv. Reg. 
Anim. ii. 46. and iv. t. 5. f. 5. ; which has somewhat the 
manner of colouring, but is very distinct from the Gecko 
ocellatus of Oppel.
