Hah. Arctic seas. 



This species is remarkable for the large size of the body- 

 whorl in comparison with the rest of the shell. When viewed 

 with the back towards the eye it occupies rather more than 

 two thirds of the entire length. There is the faintest indica- 

 tion of an angle around the upper part of the whorls. 



Bela obliquigradata. 



Testa breviter ovato-fusiformis, turrita, pallide rufescens ; anfractus 

 6, primi duo laeves, convex!, caeteri superne oblique tabulati et 

 angulati, infra unguium planiusculi, costis longitudinalibus nume- 

 rosis (circiter 20) tenuibus, supra angulum arcuatis, infra eum 

 fere rcctis, et liris spiralibus contiguis sed baud maxime con- 

 spicuis praeter in anfract. superioribus, instruct! ; anfr. ultiini 

 costse versus basim obsoleta), lira?que spirales teuues ; apertura 

 parva, angusta, longitudinis totius quam ^ paulo minor ; colu- 

 mella laevis, callo albo incrassata ; labium supra angulum levis- 

 sime sinuatum ; canalis bievis, angustus.

Hah. — -? 



In the third and fourth whorls the spiral lirations are about 

 two or three in number, one encircling the angulation and the 

 rest below it ; they are rather stronger than the longitudinal 

 ribs and give the whorls a cancellated aspect. In the last 

 whorl these lirse are much finer, very numerous, and closely 

 packed. The two nuclear whorls are large, smooth, and 

 white. 



Cithara vitiensis. 



Testa ovato-fusiformis, soidide albida ; anfract. 8, piimi 2 laeves, 

 caeteri convex!, costis crassis lotundatis (in aufr. ultimo 11 basi 

 continuis) instruct!, ubique minute spiralitei striati, sutura undu- 

 lata sejuncti ; apertura angusta, longit. totius i-^ adaequans ; 

 columella callosa, leevis ; labrum extus valde incrassatum, iutus 

 denticulis circiter 10 munitum, superne levissime sinuatum ; 

 canalis bievissimus.

Hah. Totoya, Fiji Islands. 



The nearest ally to this species is C. turricula, Reeve, from 

 which it is distinguished by the less deep suture, by the 

 thicker and more rounded ribs, and shorter aperture. There 

 is a faint indication of spiral extremely pale brown lineation.
