REPTILES.

Found at Bahia Blanca by Mr. Darwin. The specimens are probably all of 
them very young; hence the longitudinal lines can scarcely be considered as per- 
manent, as most species of the genus are beautifully lineated in the young state. 
The length of the tail, with its carinated scales, the general elegance of the form, 
the gracile form of the head, and the neat and distinct arrangement of the colours, 
render this one of the most beautiful species of this elegant genus. 
The description of the colours given above, being from specimens which have 
been long in spirits, it is necessary to state that Mr. Darwin has the following 
notice respecting one of them — “ On the sides two dark red streaks ; tail red.” 
Familia — ZONURIDJ5. 
Genus — Gerrhosaurus. Weigmann.

Corpore cum caudd longo, seiyentiformi ; pedihus parvis; squamarum submaxillarum 
pari secundo contiguis ; squamis dorsalibus magnis, subreciangularibus, striatis, in 
seriebus tredecem, et ventralibus in seriebus octo dispositis. 
Habitat, Cape of Good Hope. 
After a careful examination of the data from which the different synonyms of 
this species, and of Gerrhosaurus Jiavigularis, Bibr., have been derived, I am in- 
clined to agree with this author, that the present is the true Scincus sepiformis of 
Schneider, and of Merrem, and not Scincus Jiavigularis as supposed by Wagler, 
Weigmann, and Gray. It is very fully described by Bibron in the “ Histoire 
Naturelle des Reptiles,” but it has not hitherto been figured. There is no notice 
of it in Mr. Darwin's notes, further than its having been obtained at the Cape of 
Good Hope.
