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

 doubtful as to the propriety of admitting it among the Colmndellce ,- 

 although wherever Col. mendicar'ut 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 Purpurce, Rklnulcc 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, conko-acvminatd ; anfractibus 6 — 7, tuberculato-cos- 

 tatis, nujris, albulo nonniniqiumi varkgatis ; aperturd pallidd : 

 long. tV, Ini- iV poll. 



Hub. ad oras Americas Meridionalis. (Panama and Gallapagos.) 



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

 pletely of the characters of Columbella. 



Found with the last, under stones. 



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

 giuscvld, conico-aciiminatd ; anfractibus 6 — 7, longitudinaliter 

 tuberculato-costatis, lividis,jndlidc/uscofasciatis; lubio externa 

 intiis denticulis tribus : long. ^V, Int. -^,y poll. 

 Hah. 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 ittfra suturam serie 

 unicd, medio longitudinaliter costatis, costis decussatis : long. ^V. 

 lat. -tAjt poll. 



Hah. 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 maculutis, maculis angulatis 

 subtrapeziformibtis ; anfractu ultimo ad basin sulcato : long. -,%■, 

 lat. -^ poll. 



Hab. ad Insulam Huaheine dictam. 



ITiis 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 

 acuminata; anfractibus!, ultimo maximo ; aperturd elongatd, 

 flexuosd ; peritremalis albidi aut violacei medio intus denticulato ; 

 columella' dimidio iufcriore denticulato : long. -^\, lat. ^\t poll. 



Hah. ad oras Amcricee Meridionalis. (Panama, St. Elena, and 

 Monte Christc.) 



Found under stones ; it appears to be very common.
