202 H. B. Preston : A'ew species of Shells.' [Vol. II, 



An extremely beautiful little species and easily distinguished 

 from anj^ other member of the group. Just inside the aperture 

 appear two shell}' ridges, probably the remains of the outer lip 

 at past rest periods. 



Solariella dulcissima , sp. nov. 



Shell depressedly conoid, somewhat obtusely keeled, white, 

 painted above with large blotches of crimson, narrow radiating 

 bands of the white ground colour appearing at irregular intervals 

 between these; base of shell painted with rows of dark crimson 

 dashes and flecked with spots and blotches of a lighter shade of 

 the same colour between the rows and towards the periphery ; 

 whorls 4^, sculptured throughout with very fine, spiral lirse crossed 

 by minute transverse strise giving a fineh^ granular appearance to 

 the shell ; sutures impressed ; umbilicus moderately wide, bordered 

 by two coarse whitish ribs, the lower and coarser of which is 

 nodulous ; aperture roundly ovate ; peristome simple ; interior of 

 shell iridescent, spirally striate.

A comparison may be made between this species and 

 5. variabilis, A. Ad. ; it is, however, thinner in texture, flatter and 

 more keeled at the peripher}^; the umbilicus is also narrower and 

 the general sculpture is much finer than in 5. variabilis. 



Stomatella crenulata, sp. nov. 



Shell roundly auriform, somewhat depressed, pale pinkish 

 yellow, mottled with oblique streaks and blotches of crimson fading 

 to red and green ; whorls 5 , sculptured with light spiral ridges ; the 

 interstices marked with fine, wavy, spiral striae except on the base 

 of the shell where these last are absent, both crossed with transverse 

 strise presenting a slightly beaded or granular appearance ; sutures 

 crenulate above, incised below ; columella descending obliquely in 

 a rounded curve ; umbilical region surrounded b}^ a broad white 

 callus ; peristome acute ; interior of shell highly iridescent.
