8. DESCRIPTION OF NEW SPECIES OF MARINE SHELLS FROM
THE PACIFIC ISLANDS. By W. HARPER PEASE.
CYPRlEA GRANUJ.ATA.
T. ovata aut obeao-ovata, aubgibbosa, subtenui, extremitatibua viz productis; dorso granuloso aut noduloso, nodulis latel'alibus liris coadunatis, sulco dorsali vix impresso; lateribus submarginatis; baai convexa, lirata, liris remotis, per busem par tim extensis, interdum liria intermediis; apertw'a angusta, antice latiore, lactea aut pallide rufeacenti-fuaca, nodulis albidia, rufescenti-fuaco annulatis, lil'is rufescenti-fuscis; basi alba, liris basalil)'us rufo-fuscente mm'ginatis, ext1'emitatibus 1'ufescenti-fu8cia tinctis.
Shell rather light, O\'ate, or obesely ovate, somewhat gibbous; extremities slightly produced; back granulose or nodulous; nodules irregular in size, those near the margins connected by ridges; the ridges terminating at the margins, and seldom reaching the dorsal region, impressed by a slight dorsal groove, which is sometimes obsolete; sides slightly margined; base convex, ridged; ridges remote, especially those on the columella not extending to the margin, aud those on the columella not reaching the inner edge, with the exception of a few of the anterior ones; occasionally a few short intermediate ridges; aperture narrow, slightly the wider anteriorly; creamcolour or light reddish-brown; nodules whitish, sometimes encircled by reddish-brown rings; ridges of the same colour; base white; basal ridges edged with reddish brown, and extremities stained with the same colour.
Length 32, breadth 20 mill. From an examination of living specimens of the above species, .
from several parts of the Pacific, we are satisfied it is quite distinct from tbe C. nucleus or C. madagalical'ensis, with which it bas been heretofore confounded. It differs from both of the above species in being lighter, and in the basal ridges being less in number and not extending to the margin, or becoming nearly obsolete as they approach
* The description of Pupina mouhoti will be given in a subsequent paper.
