anfractibus convexis, sutur^ validA,, aperturi ovatS, 

 labio interne fusco-nigricante, externo intus sul- 

 catOj albo, margine denticulatOj aurantiaco, dente 

 quinto ab basim prominente. 



Obs. Six specimens in the collection aU accord 

 perfectly in the characters above given^ the longi- 

 tudinal undulations, or folds, are very prominent, 

 and the transverse ribs, or grooves, run over them. 

 It is remarkable that the fifth tooth from the base of 

 the outer lip is the largest, and that it corresponds 

 to a groove that is more deeply marked on the out- 

 side than the others. This shell resembles B. Tran- 

 quebaricum in general form; in the latter remark- 

 able chara,cter, however, it will be found to differ 

 materially. There are some fuscous spots sprinkled 

 over the ribs. 



1963. EBURNA PAPILLARIS. 



E. test^ oblongo-conoidea, polita, alba, punctulis nu- 

 merosissimis fuscis ; spirse apice papilloso ; anfrac- 

 tibus rotundatis, superne depressis ; columellae 

 basi acut^ : long. \4o lat. 1 unc. 



Obs. One specimen of this pretty shell adorns 

 this collection, it is the second that has come under 

 our observation, another, which was in the African 

 Museum, being in JNIr. Broderip's possession. The 

 species has not the spiral channel within, that dis- 

 tinguishes others of the genus. 



1694. EBURNA AMBULACRUM, 



E. test^ ovali, apice acuminata, Isevi, albida, maculis 

 transverse oblongis, fulvis : spira brevi, anfracti- 

 bus ventricosis, superne eanaliculatis, umbilico va- 

 lido, intus Isevi : long. 1 ^-^ lat. 1 unc. 



Obs. This shell approaches very nearly to E. spi- 



rata, from which, however, it may be distinguished
