2i2 Mr. E. A. Smith on Mollusca from the 



12. Fusus captivus. 



Testa fusiformis, parva ?, sordide albida, rufo lirata ; anfractus 8, 

 convexi, supremi duo laeves, globosi, caeteri costis 10-11 teiuiibus 

 oblujuis arcuatis instruct!, liris transversis duobus circa medium 

 cincti, lineisque spiralibus iiliformibus paucis ornati, increnienti 

 lineis striati, ultimus liris praecipuis circiter 12 succinctus ; aper- 

 tura alba, lougit. totius | sequans ; labrum tenue, intus liris 

 intrantibus 8-9 munitum ; columella callo tenui induta, superne 

 arcuata ; canalis anterior obUquus, subrecurvus, baud elongatus. 



Longit. 22| millim., diam. 8| ; apertura 11 longa, 3 lata. 



Hah. Station 233, oflf Andaman Islands, 185 fath. 



Tlie fine thread-like spiral Hues being crossed by rather 

 distinct lines of growth, give to the surface a finely latticed 

 appearance. Allied to F. nipom'cus, Smith. 



13. Xassaria Icevior. 



Testa ovato-fusiformis, sordide albida ; spira conica ; anfractus 8, 

 duo superiores laeves, sequentes sutura canaliculata sejuncti, 

 costis tenuibus obliquis lirisque spiralibus inaequalibus gracilibus 

 tuberculatim cancellata, varicibus duobus magnis convexis in- 

 structi, in ultimo costis fere evanidis ; apertura obliqua ; canalis 

 anticus obliquus, recurvus ; labrum extra varicosum, intus liris 

 intrantibus circiter 14 instructum ; columella in medio arcuata, 

 callo tenui iuduta, supra et infra transversim lirata, at supra 

 marginem canalis tuberculis paucis parvis munita. 



Longit. 26 millim., diam. 16. 



Ilab. Station 237, lat. 13° 17' N., long. 93° 7' E., off 

 Andaman Islands, 90 fath. 



The large swollen varices, two upon each whorl, are very 

 faintly tinted with rose. The longitudinal costee, which are 

 only feebly indicated upon the body-whorl, become more 

 pronounced and fewer upon each whorl as they advance 

 towards the apex. The transverse Yirss are about eight in 

 nuniber upon the penultimate whorl, and the whole surface is 

 marked witli fine lines of growtli. 



Closely allied to N. nivea, Gmelin, jy. twrita^ Sow., and 

 N. mu/iipUcaia, Sow., and chiefly distinguished by the 

 smoother body-whorl and the swollen varices. All four 

 forms might well be regarded as varieties of one and the same 

 species.
