The varicose peculiarity of growtli whicli cluiracterizes 

 the ./. leucozonias, is developed in a less prominent degree in 

 this species, the contrast of painting being reversed. The 

 .4. leucozonias, is of a dark chestnut-browu marked with 

 longitudinal white stripes, in places where the white- 

 edged lip has been matured after the manner of a vai-ix. In 

 the present species the shell is of a uniform orauge-yeUow, 

 and the periodical matiu-ity of the lip is indicated in its 

 eo\n-se of growth, about four to five times in a whorl, by 

 a broad chestnut stripe.

The Peruvian Achatina. Shell fusiformly oblong, 

 sutures of the spire peculiarly deeply excavated, 

 whorls rather flatly convex, longitudinally very closely 

 finely ribbed, interstices marked transversely with 

 grooved striae, columella twisted and abruptly trun- 

 cated, aperture oblong ; white, conspicuously painted 

 with red-brown longitudinal flames and oblique lines.

This species belongs apparently to a distinct type, the 

 chief peculiarity of which resides in the deeply grooved 

 formation of the sutm'es. It is of rather solid texture 

 mth somewhat the aspect of a marine shell, finely ribbed 

 longitudinally, the ribs turning over the upper edge of the 

 whorls into the sutural depression. In painting it is richly 

 marked with red brown stripes, crossed ohliquely with 

 fine lines of the same colour. 



Species 58. (Mus. Cuming.)

The smooth Achatina. Shell acuminately ovate, rather 

 thin, whorls seven to eight in number, very finely 

 longitudinally striated, smooth, shining, columella 

 short, arched and twisted ; light fulvous horn-colour, 

 ornamented with distant brown streaks, descending 

 from the sutm'es to the middle of the whorls.

This species has a smooth glazed appearance, but not 

 arising from the lustre of a horny cuticle, such as that 

 which characterizes the A. Lattrei and its congeners.
