acuminata, peritremate tenui, aeuto, supra umbilicum. paululiim 



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 strise ; the spire is rather elevated and 

 acuminated, but the apex is obtuse : volutions five, very regularly 

 roimded, and very finely transversely striated, the transverse strise 

 decussating the spiral striae, and the posterior strise 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.

Hab. ? 



This beautiful species, received by Mr. Cuming from A. L. Gubba, 

 Esq. of Havre, is materially distinct from any hitherto described. It is 

 of a swollen ovate form wdth 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 

 Ught fulvous spots all inclining towards the lip, which is of a deUcate 

 flesh-pink. 



4. Description of a new species of Box Tortoise from 

 Mexico. By J. E. Gray, Esa., F.R.S. etc. 



(ReptiUa, PI. 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 being only 

 armed wdth 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 Emydce. 



This species will form a section or subdivision of the genus, which 

 may be called Onychotria.
