 There is a singular peculiarity attending this species in 



the manner in which the epidermis, especially on the 



l)and which is sometimes seen beneath the sutui-es, is 



abraded, denuding the shell in patches.

The leopard Bdlimus. Shell somewhat shortly ovate, 

 ventricose, whorls five in number, convex, very 

 closely sculptured longitudinally with fine rib-like 

 strise, last whorl exceeding the length of the spire, 

 columella aj'ched, aperture very large; yellowish- 

 chesnut, variegated with a scattered whitish epider- 

 mis upon a thin horny one, peritreme purple-chesnut.

This remarkable species, of which Mr. Cuming has only 

 the single specimen here represented, is distinguished from 

 all others by the effused and suddenly enlarged develop- 

 ment of the last whorl. It is also characterized by a 

 regidar succession of longitudinal rib-like strise of a more 

 defined growth than the ordinary lines of structure, which 

 in a genus so devoid of sculpture is an important feature. 



The name is suggested by the scattered interrupted 

 stripes in which the outer hydrophanous epidermis is de- 

 posited. The columella, it should be observed, has a 

 pinky hue, and the impress of the striae imparts a delicate 

 satinv irridescence to the interior of the shell.

The pretty Bulimus. Shell pyramidally oblong, whorls 

 six in number, flatly convex, aperture contracted, lip 

 reflected ; chesnut-brown, epidermis' prettily flamed 

 and marbled with white, columella and interior of the 

 aperture bluish white, peritreme dark chesnut.

 I much doubt whether this is anything more than a 



variety of the B. leucophaa ; it is, however, a well-marked 



and extremely pretty one.
