2. C. ROLPH'II,* GRAY. PL. IX. 



Body of a very dark reddish-brown above, lighter brown 

 underneath, tubercles more or less black, placed in close-set 

 lines ; mantle yellowish-white, spotted with white ; tentacles 

 nearly opaque, greyish-brown, upper pair rather short and thick, 

 slightly shagreened, and covered with exceedingly minute black 

 specks, bulbs thick ; lower tentacles very short, lighter in colour 

 than the upper pair ; foot very long and narrow, sole greyish. 

 Viviparous (Rich). 



Shell spindle-shaped, rather thin, almost semitransparent, 

 glossy, brown, or yellowish - brown, with numerous strong, 

 regular, close-set curved striae in the line of growth, which 

 are less numerous, slightly flexuous, wider apart and stronger 

 towards the base of the shell ; periphery angulated ; epidermis 

 moderately thick ; whorls 9-10, ventricose but slightly com- 

 pressed ; spire tapering abruptly, apex obtuse and (as are the 

 two whorls beneath it) quite smooth and glossy ; suture rather 

 shallow and somewhat oblique ; mouth slightly quadrangular, 

 contracted above, sinuous on the outer side, and considerably 

 dilated below ; plaits similar to those of the last species, but 

 the lower one on the base of the penultimate whorl is less pro- 

 minent and frequently cruciate; outer lip detached, thick, whitish, 

 reflected ; basal crest curved ; umbilicus indistinct ; clausium 

 oblong. 



Inhabits moist places in woods, under stones, among 

 moss, dead leaves, nettles, and dog's mercury, and on 

 the bark of trees in a few localities in England, but it 

 is a rare species. It has been observed in the follow- 

 ing counties : Kent, Sussex, Hampshire, and Glouces- 

 tershire, and Mr. W. G. Blatch has found it near 

 Newton Abbot in South Devon. 



Named after Mr. Rolph, who was the first to notice it in England
