The fine thread-like spiral lines being crossed by rather 

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

 appearance. Allied to F'. niponicus, Smith. 



13. Nassaria Jcevior. 



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

 duo superiores la^ves, sequentes sutura canaliculata sejuncti, 

 costis teijuibus obliquis lirisque spiralibus insequalibus gracilibus 

 tuberculatim cancellata, varicibus duobus magnis convexis in- 

 struct!, in ultimo costis fere evanidis ; apertura obliqua ; canalis 

 anticus obliquus, recurvus ; labrum extra varicosum, intus liris 

 iutrantibus circiter 14 instructum ; columella in medio arcuata, 

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

 marginem canalis tuberculis paucis parvis munita.

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

 faintly tinted with rose. The longitudinal costge, 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 lirse are about eight in 

 number upon the penultimate whorl, and the whole surface is 

 marked with fine lines of growth. 



Closely allied to N, nivea, Gmelin, i\^. turritaj Sow., and 

 N. vnilfiph'cata, 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. 



14. Tritonidea delicata.
