acuminatd, peritremate tenui, acuto, supra umbilicum paululim 
reflexo. 
A species somewhat resembling C. ligatum, but differing in several 
characters. It is suborbicular and thin, smooth, whitish, posteriorly 
with several narrow slightly interrupted chestnut-coloured bands and 
close-set very slender spiral strie; the spire is rather elevated and 
acuminated, but the apex is obtuse: volutions five, very regularly 
rounded, and very finely transversely striated, the transverse strize 
decussating the spiral striz, and the posterior strize being the most 
distinct, the anterior being almost undistinguishable: the umbilicus 
is large, very finely spirally striated within ; aperture large, nearly 
circular, slightly acuminated posteriorly, with a thin, sharp-edged 
peritreme which is rather wide and slightly reflected over a part of 
the umbilicus. 
From Madagascar, in the collection of A. L. Gubba, Esq., Havre.

Hab. ? j 
This beautiful species, received by Mr. Cunning from A. L. Gubba, 
Esq. of Havre, is materially distinct from any hitherto described. It is 
of a swollen ovate form with the spire rather sharply acuminated, and 
the columella is distinguished by a sharp winding plate. The ground 
colour of the shell is a reddish purple, the last whorl being particu- 
larly characterized by a thin ash-coloured epidermis sprinkled with 
light fulvous spots all inclining towards the lip, which is of a delicate 
flesh-pink. ' 
4, DESCRIPTION OF A NEW SPECIES OF Box TorRTOISE FROM 
Mexico. By J. E. Gray, Esa., F.R.S. etc. 
(Reptilia, Pl. II.) 
In a collection of reptiles recently received from Mexico are two 
specimens of a Box Tortoise, which, beside differing from the com- 
mon box tortoise of North America, in being of a more elongated 
form, both agree in two characters, which are not found in that 
species or in any other species of the genus; first, in having an 
additional vertebral plate ; and secondly, in the hind feet bemg only 
armed with three large claws: there is no appearance of the fourth 
claw, and even scarcely any rudiment of the fourth toe found in the 
other specimens of this genus, and in all other Emyde. 
This species will form a section or subdivision of the genus, which 
may be called Onychotria.
