ACHATINA SMITHU, sp. IIOV. (Plate LVII. fig. 1.) 



Shell ovately conical, thin, semitransparent, striated by the lines of 

 growth, which, upon the upper whorls and upper part of the last whorl 

 are crossed by coarse spiral strije, producing a granulose striated 

 appearance ; whorls 8, somewhat convex, the last occupying about 

 half the entire shell ; upper whorls of a dull orange-yellow, last 

 whorl of a greenish yellow, the whole marked with numerous irre- 

 gularly waved stripes of a burnt-sienna colour ; spire somewhat elon- 

 gated, apex obtuse ; suture deep; aperture elliptically ovate, interior 

 having a faint purple lustre and showing the stripes through the 

 shell ; columella arcuate, terminating in a small truncation ; peri- 

 stome simple. Length 55 millims., greatest breadth 27, height of 

 aperture 29], breadth of aperture 15. 

 Locality. Leydenburg, Transvaal. 



I propose to name this shell after Mr. E. A. Smith, of the British 

 Museum.

 semitransparent, regularly lirate, very pale horn-colour ; spire some- 

 what produced, apex not very acute ; whorls 4, the last very convex

This species is remarkable for the regularity of the lira;.
