This species somcvvhat rcsembles Col me.mUvuria. Mr. Sovverby is 

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

 although \vherever Col. memiimr'm is placed this species mušt of course 

 follovv, Perhaps it might not be inconvciiient to separate tiiese from 

 Columbella, and to combine tliem \vith their cognate species from 

 among Lamarck's Furpune, RidnuUe and Murices, and thus biing 

 together a number of shells which vvould foim a very natūrai genus. 



^ Columbella Maura. Col. teaUi ovatd, medio turgitUl ; spird lon- 

 giusculd, conico-acuminatd ; luifractibus 6 — 7, tuherculato-cos- 

 tatis, iiigris, albido nonnunųuam variecjatis ; aperturd jiuUidd : 

 lo7ig. ^\, lut. ,V poli. 

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

 Somevvliat related to the lašt, thougli partaking rathcr less com- 

 pletely of the characters of Columbella. 

 Found witli the lašt, under stones. 



Columbella livida. Col. testd ovatd, medio turgldd į spird lon- 

 giusculd, conico-acumiiiatd ; anfractibus 6 — 7, longitndinaliter 

 tuherculato-costatia, lividis, pallide fasco fa.fciatis ; labio externo 

 intus denticnlis tribus : long. iV, lat. -f^ poli. 

 Hab. ad Panamam, sub lapidibus. 



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

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

 the genus. 



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

 nigro-punctatd ; anfractibus 6, tuberculorum infra sv turam serie 

 unicd, medio longitudinaliter costatis, costis decussatis : long. VV. 

 lat. -Ąy poli. 



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



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



Found on the Meleagrince. 



Columbella obtusa. Col. testd oblongd, subn/lindricd, Icevi ; an- 

 fractibus 8, albicantibus, castaneo maculatis, maa/lis angulatis 

 subtrapeziformibus ; anfractu ultimo ad basin sulcato : long. ^V. 

 lat. -rv poli. 



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 fuscd indiitd ; spird 

 acuminatd ; anfractibus 7, ultimo ma.vimo ; aperturd elongatd, 

 fleocuosu ; peritrcmatis albidi aut violacei medio intus denticulato ; 

 columellce dimidio inferiore denticulato : long. vV, lat. n\, poli. 



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

 Monte Christc.) 



Found under stones ; it appears to be very common.
