Pachydactylus dubius, Boettger, Zool. Anz. 1881, p. 46, and Abh. 

 Ver. Brem. vii. p. 179, and Abh. Senck. Ges. xii. p. 464, from Nossi 

 Be, is perhaps a young P. madagascariense ; the characters upon 

 which that form now rests seem hardly sufficient to admit it as a 

 species. The following is an abstract of the description : — 



In habit intermediate between P. madagascariense and P. lati- 

 cauda. Rostral with a median cleft above ; nostril pierced above 

 the first upper labial ; naso-rostrals separated by three scales ; chin- 

 shields four on each side, of equal size, scarcely larger than the 

 surrounding gular scales. Dorsal scales rather large, smooth ; 

 abdominal scales smooth. Caudal scales smooth ; the caudal segments 

 composed of five or six transverse rows of scales above. Femoral 

 pores twelve or thirteen on each side. Ileddish brown above, spotted 

 and variegated with yellowish anteriorly, with bluish posteriorly ; 

 two blackish lateral streaks ; lower surfaces whitish, immaculate.

Snout once and two thirds as long as the distance between the 

 eye and the ear-opening, twice the diameter of the orbit, llostral 

 without median cleft ; nostril pierced above, and bordered beneath 

 by the first upper labial ; eight to ten upper labials ; seven to 

 nine lower labials ; chin-shields eight, subeciual, the inner pair 

 hardly larger than the outer ; generally a single scale between the 

 naso-rostrals. Vertical diameter of the ear-opening about half the 

 diameter of the orbit. Dorsal scales smooth or more or less di- 

 stinctly keeled. Ventral scales smooth. Femoral pores thirteen or 

 fourteen on each side. Tail much depressed, nearly as broad as 

 the back ; segments of tail not very distinct, composed each of six 

 or seven transverse rows of scales on the side, eight to ten on the 

 upper surface ; lower surface generally very irregularly plated ; the 

 scales on the upper surface generally keeled, Grreen above ; 

 head with two or three rather indistinct reddish cross bars, the 

 anterior Y-shaped, extending from one eye to the other ; some- 

 times a few large reddish spots on the hinder part of the back ; a 

 blackish band from the eye along the side of the neck and body, 

 passing through the ear and over the shoulder, darkest as it 

 approaches the groin ; limbs and tail dotted or vermiculated with 

 blackish ; lower surfaces whitish, throat generally greenish, im- 

 maculate.
