Original Descriptio7is of Achati7iella. 115 



columellar folds strong, \vhite, nearly transverse; aperture slightly 

 oblique, sinuously oval, bluish white within ; peristome thickened 

 within; with anterior margin slightly refledled ; columellar margin 

 dilate, white, unattached; parietal margin very thin, or wanting. 



Length 0.S3 in. (21 mill.), breadth 0.50 in. (12 2-3 mill.). 



Length of aperture 0.40 in. (10 mill.). 



Average weight 6.70 grains. 



Var. B. Ash-brown, with whitish streaks in spots. This 

 variety passes into A. laidosa Nob. 



Var. C. With a white band on the periphery of the last 

 whorl ; very rare. 



Var. D. Small, ovate-conic. The dimensions of one of the 

 smaller specimens are as follow^s: 



Length 0.70 in. (18 mill.), breadth 0.40 in. (10 mill.). 

 Length of aperture 0.34 in. (8 2-3 mill.). 

 Weight 4.00 grains. 



Var. E. Lip considerably expanded and refle(5led, slightly 

 thickened within, columella broadly refiedled. This variety pre- 

 sents a remarkable feature; appearing as if the body w4iorl had 

 been enlarged, and the lip expanded by a second growth after the 

 shell had been perfecfted, and the lip thickened. The second 

 growth forms a broad lip, sometimes an eighth of an inch or more 

 in width, from the interior callous ridge to the edge. This lip 

 seems to be of the same material as the thickening within, the ex- 

 terior being of an unpolished ivory color, not covered wath the 

 brown coat which clothes the rest of the shell. The interior of 

 both the lip and columella is of polished ivory-white; aperture 

 within the lip bluish white. Specimens presenting more or less of 

 the features of this variety are not rare.
