Hab. ad Sitka, Nova Albion (on orks: half-tide) ; collected by 
Mr. Barclay. 
Very nearly allied to L. groenlandica, but more depressed, blunt, 
the aperture more dilated. The elevated transverse lines are three 
in number on the upper volutions, about twelve on the last. 
6. Lirrornina eiaBrata. Lit. testd ovato-oblongd, acutd, albido- 
carned, strigis pallide fuscis obliquis pictd; anfractibus pariim 
convexis, levibus, supremis sub lente lineis impressis 6-8 exaratis, 
ultimo basi angulato ; apertura ovatd, rufa; columelld depressd, 
violaced.

Hab. ad Payta Peru (on rocks, half-tide) ; Cuming. Ad Caput 
Natale (Wahlberg). 
Perhaps only a variety of L. obesa, Sow., though easily distin- 
guished by the pale oblique longitudinal lines : very like L. ziczac, 
D’Orb. (non Chemn.) 
7. Lrrronina tavis. Lit.testd ovato-oblongd, acutd, albidd, cinereo- 
marmoratd ; anfractibus pariim convexis, levissimis (sub lente 
fortiori vix tenuissime striatis) ; ultimo basi obscure angulato ; 
aperturd ovatd, fusco-violaced, basi albido-fasciatd; columelld 
depressd, violaced.

This species scarcely differs, except in colouring, from L. obesa. 
8. Lirrorina pesitis. Lit. testd parvd, ovato-oblongd, acutd, tenui, 
cerulescente-albidd, interdum lineis obliquis pallidissime fuscis

Jertis impressis sculptis), ultimo basi angulato; aperturd ovato-

depressd, fuscescente. 
Altit. 43, diam. 3, altit. aperturee 24 lin. 
Hab. Unknown. 
A L. glabrata in miniature; it differs however essentially from 
that species by its aperture, which is produced into a distinct angle 
at the base.
