mottlings, rather indistinct, on the back, and a clear yellow 

 spot on the hind part of the thigh, close to the root of the tail, 

 which is banded alternately with dark and pale brown. 

 One specimen from the Gaboon, 4f inches long. 



Goniodactylus caudiscutatus, Giinth., 



does not offer the peculiarity mentioned by M. Bocourt, in 

 ' Miss. sc. Mex.' p. 48, as characteristic of the G. fuscus of 

 Hallowell, viz. that the mental plate is followed by a single 

 large postmental in place of the row of small plates found in 

 G. albogularis. The specimen bearing this name referred to 

 by him is no doubt a different species ; as there are specimens 

 in the British Museum from Panama with a large single post- 

 mental ; and these being different from Dr. Gunther's species, 

 I have named them, in accordance with M. Bocourt's differen- 

 tiation, G. fuscus. 



Goniodactylus Braconnieri, sp. n. 



This form is referred to by Dumdril, in 'Arch, du Mus/ viii. 

 p. 473, as a variety of G. albogularis. It is distinguished 

 from it by the conspicuous coloration of the gular region ; and 

 the British Museum has as yet received it only from the 

 South-American continent, whereas G. albogularis appears to 

 be a West-Indian species. 



The whole of the chin is of a light colour, separated abruptly 

 from the dark hue of the chest, which envelops the sides of 

 the body, extending more or less on the belly. A straight 

 white stripe, bordered with greyish, forked behind the mental, 

 and dividing into two branches, extends the length of the chin 

 to the chest. Another lateral stripe on each side curves 

 upwards from before the chest towards the eye ; and two blue 

 spots on the supralabials beneath the eye correspond severally 

 with the curved stripe and the lateral branch of the median 

 gular stripe. There is also a vertical humeral band. The 

 upper surface of the body is variegated like G. albogularis, 

 being either (1) marbled with dark and light brown or (2) 

 very finely punctulated. 



Several specimens have been obtained from Barranquila, 

 New Granada, and one, which agrees completely with them, 

 bears the locality of Chili. 



Goniodactylus sidcatus, sp. n. 



Head narrow, sharply descending from the supraorbital 

 region to the extremity of the snout. Supralabials six ; infra- 

 labials five. Mental large, truncated behind, followed by two, 

 small, hexagonal postmentals, and these by one or two rows
