ZOOLOGY OF FEIOTATSTDO NOKONHA.

REPTILXA. 
By G. A. Boulekger, F.Z.S., 
Assistant in the Zoological Department, British Museum. 
Only three species were found, viz. a Gecko ( Hemidactylus 
mabouia , Mor.), a Skink (Mabuia punctata. Gray), and an Amphis- 
bcena , described below. 
The Gecko is of a widely-distributed species, ranging over the 
greater part of Tropical America and Africa. 
The Skink was originally described from two specimens ob- 
tained on Fernando Noronha by H.M.S. c Chanticleer,’ but has 
since been recorded from Demerara. The specimens brought 
home by Mr. Bidley are 10 in number; two have 36 scales round 
the body, the others 38 ; in one specimen the frontonasal touches 
the rostral and in another the two shields form a narrow suture. 
AMPHISBiEFTA BlDLEYI, Sp. 11. 
Under this name I propose to designate an Amphisbcena of 
which a specimen, stated to be from Porto Bello, West Indies # , 
presented by Capt. Austin, B.N., has been in the British Museum 
for nearly 50 years, and was referred by Gray, Strauch, and 
myself to A. caeca, D. & B. The same species has been found 
by Air. Bidley on Fernando Noronha, and on re-examining the 
question I find, that A. caeca , which occurs on various West- 
Indian Islands, but which was unrepresented in the British 
Museum when I published my Catalogue, must be regarded as 
distinct from the one with which I have now the pleasure of 
connecting Air. Bidley’s name. 
16 specimens were collected by Air. Bidley. One has 180 annuli 
on the body, one 181, one 182, three 183, two 185, two 186, one 
187, one 188, one 189, one 190, one 195, and one 196 ; two have 
18 annuli on the tail, eleven 19, and three 20. The “ Porto- 
Bello ” specimen has 189 annuli on the belly, and 19 on the tail. 
The number of annuli in five specimens of A. caeca (including 
the type) recorded by Strauch are respectively 212 + 15, 215 + 13, 
227 + 18, 230 + 16, and 247 + 15. Dumeril and Bibron give 
226-329 + 18. A specimen from Porto Bico, which I owe to the 
* I am unable to find such a place either in the West Indies or Northern 
Brazil, but as the other of the two specimens presented by Capt. Austin as from 
“ Porto Bello ” belongs to a North-Brazilian species (Amphisbcsna vermicularis), 
I entertain little doubt that both were obtained in Brazil.
