This species somewhat resembles Col. mendicaria. Mr. Sowerby is 

 doubtful as to the propriety of admitting it among the Colvmbellco ; 

 although wherever Col. mendicaria is placed this species must of course 

 follow. Perhaps it might not be inconvenient to separate these from 

 Columbella, and to combine them with their cognate species from 

 among Lamarck's Purpura, Ricinula: and Murices, and thus bring 

 together a number of shells which would form a very natural genus. 



^ Columbella Maura. Col. testd ovatd, medio turgidd ; spird lon- 

 giusculd, conico-acuminatd ; anfractibus 6 — 7, tuberculato-cos- 

 tatis, nigris, albido nonnunquam variegatis ; aperturd pallidd : 

 long. ^%-, tot. -iV poll. 

 Hab. ad oras Americse Meridionalis. (Panama and Gallapagos.) 

 Somewhat related to the last, though partaking rather less com- 

 pletely of the characters of Columbella. 

 Found with the last, under stones. 



Columbella livida. Col. testd ovatd, medio turgidd ; spird lon- 

 giusculd, conico-acuminatd; anfractibus 6 — 7, longitudinaliter 

 tuberculato-costatis, lividis, pallide fusco fasciatis ; labio externo 

 intiis denticulis tribus : long. -jfo, tot. -/o- poll. 

 Hab. ad Panamam, sub lapidibus. 



This differs from the two last in several particulars, though it is so 

 intimately related to them as to form a part of the same division of 

 the genus. 



Columbella nigro- punctata. Col. testd ovato-acuminatd, albd, 

 nigro-punctatd ; anfractibus 6, tuberculorum infra suturam serie 

 unicd, medio longitudinaliter costatis, costis decussatis : long. T V» 

 lat. -jrV poll. 



Hab. ad Insulas Polynesias. (Lord Hood's Islands.) 



Somewhat related to, but distinct from Lamarck's Col, zonalis. 



Found on the Meleagrince. 



Columbella obtusa. Col. testd oblongd, subcylindricd, Icevi ; an- 

 fractibus 8, albicantibus , castaneo maculatis, maculis angulatis 

 subtrapeziformibus ; anfractu ultimo ad basin sulcato : long. -iV, 

 tot. iV poll. 



Hab. ad Insulam Huaheine dictam. 



This appears to be a very rare species, since only two specimens 

 were found on the reefs of Huaheine, one of the Society Islands. 



Columbella fuscata. Col. testd ovato-acuminatd, medio ventri- 

 cosd, castaned, albido guttulatd, epidermide fused indutd ; spird 

 acuminatd ; anfractibus 7, ultimo maximo ; aperturd elongatd, 

 flexuosd ; peritrematis albidi aut violacei medio intus denticulato ; 

 columella? dimidio inferiore denticulato : long. T V, tot. n V poll. 



Hab. ad oras Americae Meridionalis. (Panama, St. Elena, and 

 Monte Christe.) 



Found under stones ; it appears to be very common.
