MOLLUSCA,

Shell conic, pellucid, light hom-colour ; with seven moderately rounded vo- 
lutions, and generally two pale, yellowish bands on the body ; finely and regu- 
larly spirally striate throughout ; apex pointed ; aperture subovate ; outer lip 
thin even ; pillar lip a little reflected on the columella. 
This species differs from the R. inscidpUis in its colour and pointed apex ; 
and in having no duplicature or subumbilicus behind the pillar lip, and being 
destitute of the small tooth. Length a line and a half ; breadth not a line. 
Found at the South Bull, Dublin Bay, by Dr. Turton, who says, “ We foimd 
a variety more conic and paler, with yellowish marks on the body whorl, which 
is larger in proportion to the rest, and all are rounded and deeper defined.’’

This shell differs fi-om the R vitrea, in the body being much larger in pro- 
portion to the length of the spire, and being oviform in its outline ; the volu-

its shape, with the outerlip not so abruptly produced.
