DESCRIPTION OF NEW SPECIES OF SHELLS. 

 BY W. I). IIARTMAX, M. D. 

 Bulimus ruga, Nobis. PI. Ill, fig. ]. 



Shell moderately thick, transluceut, ovate elongate, body-whorl 

 somewhat inflated. Whorls 5i, rounded, suture impressed, crenu- 

 late. Four apical whorls with minute spiral stride, aperture round- 

 ed oval. Spire half the length, epidermis absent, oblique lines of 

 growth coarse, umbilicus compressed, lip white, reflected, flat, with 

 a heavy deposit on the pillar lip. Color white. 



Height 28 mm., width 15 mm. ; height of aperture 10 mm., width

Obs. This shell (of which I have seen but two weather-beaten 

 examples) has the facies of a Partula (to which it may be eventually ' 

 assigned). At every stage of growth, the upper angle of the labium 

 leaves a fold on the suture, giving it the appearance of a ruffle, 

 hence the name.
