 This shell, at a glance, has very much the appearance of the Mitra 

 pulchella, but upon examinatioii it will be observed that the dark 

 oand which encircles the one is painted on the ribs, whilst in the 

 other it appears in the interstices.

This new and very characteristie shell exhibits the šame peculiarly 

 contracted structure as the Mitra abbatis, aud the whorls have the 

 šame contiguous telescope-like appearance.

In order not to confound this species with one of very similar ap- 

 pearance, the Mitra ustulata, it is important to notice that the sur- 

 face of the former is grooved throughout, whilst that of the latter is 

 very finely striated and marked with rather distant brown hair lines.
