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



cancellati ; anfr. ultimus lira spirali tertia pernio infra medium 

 ornatus ; apertura parvUy longit. totius -^ adcequans ; columella 

 in medio unipUcata, antice suhsinuata. 

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

 In size and 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 164, but which possibly might be detected in a larger 

 series of specimens. 



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



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



globosus, cceteri superne anguste tahulati, ad latera vix convex- 



iusculi, costis crassis (in anfr. ult. plus minus ohsoletis) circiter 



15 histructi, linea im,pressa spirali infra suturam sculpti, 



ultimus infra medium constrictus, antice sulcis paucis circa cau- 



dam sculptus ; apertura elongata, longit. totius \ (xquaiis vel 



superans ; columella plicis quatuor tenuibus distantihus instructa. 



Longit. 9 millim., diam. 4; apertura 4| longa, 1| 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 falls 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, Icevis; anfract. 5, 

 supremus convexus, sequentes superne valde excavati, dein acute 

 angulati, ultimus infra angulum leviter convexus, basim versus 

 contractus ; apertura elongata, angusta, longit. totius ^ 

 adcequans; labrum vcdde incrassatum, intus Iceve; columella 

 plicis tribus, tenuibus sedprominentibus, instructa, antice oblique 

 curvata, per longitudinem callo tenui induta. 

 Longit. 5| 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 suhequal and thin but 

 prominent. 



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



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

 simcc, ad apicem obtuscc ; anfr actus 4, prope suturam depressi, 

 leviter Tnarglnati, ultimus mctgnus, superne late rotundeque 

 humerosus, inferne angustus, contractus ; apertura mediocriter 

 angusta, circa |- longit. totius oecupans ; columella plicis trilms 

 tenuibus instructa ; labrum extus incrassatum, intus Iceve. 

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

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

 the oblique anterior termination of the columella which passes into 

 the labrum.
