ZOOLOGY OF FEUWANDO NORONHA. 481 



REPTILIA. 



By Gr. A. BOULENOEB, F.Z.S., 



Assistant in the Zoological Department, British Museum. 



Only three species were found, viz. a Gecko {Semidactylus 

 mabonin, Mor.), a Skink {Mabuia jnmctata, Gray), and an Amphis- 

 hcEtio, described below. 



The Gecko is of a widely-distributed species, ranging over the 

 greater part of Tropical America and Africa. 



The Skink was origiually described from two specimens ob- 

 tained on Fernando Noronha by H.M.S. ' Chanticleer,' but has 

 since been recorded from Demerara. The specimens brought 

 home by Mr. Eidley 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. 



AMPHISBiENA ElDLETI, Sp. n. 



Under this name I propose to designate an Amphishcena of 

 which a specimen, stated to be from Porto Bello, West ludies *, 

 presented by Capt. Austin, E.N., has been in the British Museum 

 for nearly 50 years, and was referred by Gray, Strauch, and 

 myself to A. cceca, D. & B. The same species has been found 

 by Mr. Eidlej on Fernando Noronha, and on re-examining the 

 question I find that A. cceca, which occurs on various West- 

 Indian Islands, but whicli was unrepresented in the British 

 Museum w^heu I published my Catalogue, nnzst be regarded as 

 distinct from the one with which I have now the pleasure of 

 connecting Mr. Eidley's name. 



10 specimens were collected by Mr. Eidley. One has 180 aunuli 

 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. cceca (including 

 the type) recorded by Strauch arerespectively 212 -f 15, 215-1-13, 

 227 -f 18, 230 -M6, and 247 -f 15. Dumeril and Bibron give 

 226-329-f 18. A specimen from Porto Eico, which I owe to the 



* I am unable to find such a place eithei* iu the West Indies oi* JN'oi-tliern 

 Brazil, but as the other of the two specimens presented by Capt. Austin as from 

 " Porto Eello " belongs to a North-Brazilian species {A,Hphitih(pna vermicularis\ 

 I entertain little doubt tliat both were obtained iu Brazil.
