440 MR. E. A. SMITH ON NEW SHELLS FROM [JuilC 16, 



cancellati; anfr. ultimus lira spirali tertia paulo infra medium 

 ornatus ; apertura parva, longit. totius -^ adcequans ; columella 

 in medio uniplicata, antice subsinuata. 

 Longit. 6 millim., diam. 3 ; apertura 2| longa, 1\ lata. 

 In size aud form C.fischeri of A. Adams, from the Straits of 

 Korea, bears considerable resemblance to the present species. It has, 

 however, more spiral lirse, three columellar plaits and lirse within the 

 aperture, a feature which does not appear in the single shell at hand 

 from station 1 64, but which possibly might be detected in a larger 

 series of specimens. 



12. MiTRA MIRANDA. (Plate XXXIV. fig. 12.) 



Testa fusiformis, turrita, albida ; anfract. 7, apicalis Icevis, 



globosus, cateri superne anguste tabulati, ad latera vix convex- 



iuscidi, costis crassis {in anfr. ult. plus minus obsoletis) circiter 



15 instructi, linea impressa spirali infra suturam sculpti, 



ultimus infra medium constrictus, antice sulcis paucis circa cau- 



dam sculptus ; apertura elongata, longit. totius \ cequam vel 



superans; columella plicis quatuor tenuibus distantibus instructa. 



Longit. 9 millim., diam. 4; apertura 4| longa, Ig lata. 



The folds on the columella are very peculiar, and recall those in 



certain species of Valuta ; they are rather far apart, and do not 



all slope in the same direction. The spiral sulcus tails below the 



edge of the tabulation, producing a kind of thickened edge to it. 



13. Marginella carinata. (Plate XXXIV. fig. 13.) 



Testa breviter ovato-fusiformis, alba, polita, laivis ; anfract. 5, 

 supremus convexus, sequentes superne valde excavati, dein acute 

 angulati, ultimus infra angulum leviter convexus, basim versus 

 contractus; wjyertura elongata, angusta, longit. totius ^ 

 adcequans; labrum valde incrassatum, intus Imve ; columella 

 plicis tribus, tenuibus sed prominentibus, instructa, antice oblique 

 curvata, per longitudinem callo tenui induta. 

 Longit. 5j millim., diam. 3| ; apertura 3| longa, 1 lata. 

 The whorls are well excavated at the upper part and then rather 

 sharply keeled a little above the suture. The surface is very 

 glossy, and the columellar folds are subequal and thin but 

 prominent. 



14. Marginella brazieri. (Plate XXXIV. fig. 14.) 



Testa parva, brevis, lata, alba, polita, subpellucida ; spira brevis- 

 sima, ad apicem obtusa ; anfractus 4, prope suturam depressi, 

 leviter marginati, ultimus magnus, superne late rotundeque 

 humerosu^,'inferne angustus, contractus; apertura mediocriter 

 angusta, circa f longit. totius occupans ; columella plicis tribus 

 tenuibus instructa ; labrum extus incrassatum, intus lave. 



Longit. 4 millim., diam. 3 ; apertura 3^ lowja, 1 lata. 



This and M. carinata have three columellar folds iu addition to 

 the oblique anterior termination of the columella which passes into 

 the labrum.
