A fine new species, of which I have seen several esamples in an 

 excellent statė of preseivatiou.

 striatd ; undique badid ; columelld quadriplicatd, pUcd infimd sub- 

 obscurd; aperturd breviusculd.

This is rather an unsatisfactory species, though certainly not re- 

 ferable to any hitherto described. 



Mitra cadaverosa. Mitr. testd ovato-turritd, spira acutd; an- 

 fractibus transversim impresso-striatis, supra et infraplus minusve 

 angulatis, longitudinaliter costatis, costis ad angulos exasperato- 

 mucronatis ; albd, halteo angustofuscescente inter costas cingulatd ; 

 columelld quadriplicatd ; apertura fauce striatd. 

 Conch. Icon., Mitra, pi. 21. f. 160. 



Hab. Philippine and Lord Hood's Islands (found under stones at 

 low water) ; Cuming, 



However closely this shell may approximate to the Mitra exaspe- 

 ratą, it is uniformly white, and ahvays exhibits a strong peculiarity 

 in the band which appears in the interstices and not upon the summit 

 of the ribs. 



Mitra carnicolor. Mitr. testd subabbremato-fusiformi, liris 

 parvis subobtusis, alternis majoribus, undiąue cingulatd, liris striis 

 impressis longitudinaliter incisis ; estus pallide carneolo-fusces-

 hitherto-described species.

Hab. Gulf of Nicoya (found in mud at the depth of about seven- 

 teen fathoms) ; Hinds. 



This beautiful species, which I have the pleasure of dedicating to 

 a most zealous labourer in the field of conchological research, may 

 be recognised by its graceful form and by the keel-like elevation of 

 the ribs. 



Mitra latruncularia. Mitr. testd abbreviato-fusiformi, tenui- 

 culd, basi truncatd; transversim undique sulcatd, suleis angustis, 

 crebris, punctatis ; albidd, rubido-castaneo tessellatd etfasciatd;
