 THE Pacific Islanbs. By W. Harper Pease. 



CyPRiBA granulata. 



T. ovata aut obeso-ovata, subgibbosa, subtenui, extremitatibus vix 

 productis ; dorso granulosa aut nodidoso, nodulis lateralibus 

 liris coadunatis, sulco dorsali vix impresso ; lateribus submargi- 

 natis ; basi convexa, lirata, liris re?notis, per basem partim ex- 

 tensis, interdum liris intermediis ; apertura angusta, antice 

 latiore, lactea aut pallide rufescenti-fusca, nodulis albidis, 

 rufescenti-fusco annulatis, liris rufescenti-fuscis ; basi alba, 

 liris basalibus rufo-fuscente marginatis, extremitatibus rujes- 

 eenti-fuscis tinctis. 



Shell rather light, ovate, or obesely ovate, somewhat gibbous ; ex- 

 tremities 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 ob- 

 solete ; sides slightly margined ; base convex, ridged ; ridges remote, 

 especially those on the columella not extending to the margin, and 

 those on the columella not reaching the inner edge, with the excep- 

 tion of a few of the anterior ones ; occasionally a few short interme- 

 diate ridges ; aperture narrow, slightly the wider anteriorly ; cream- 

 colour 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 the C nucleus or C. madagascarensis, with which it has 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.
