﻿332 CONRAD'S DESCRIPTIONS OF 



TURRIS, Rumphius.— PLEUROTOMA, Lam. 



Turris ripleyana. PI. 35, fig. 21 and 29 ? Elongated, slender ; spire subequal 

 in length to body volution and beak; volutions ribbed longitudinally; ribs slight 

 and somewhat curved above, where they are interrupted by a deep revolving furrow, 

 which causes the appearance of a prominent line bordering the suture ; surface of shell 

 with revolving lines distinct on the body whorl and beak. 



FUSUS, Klein. 



Fusus novemliratus. PI. 35, fig. 18. Elongated ; spire elevated, acute ; volutions 

 seven ; longitudinally costate and transversely striated, ribs thick, prominent, rounded ; 

 suture margined by crenulated line ; body volutions having about nine distant, very 

 large rounded costse which become obsolete about the middle of the volution ; inferiorly 

 marked with longitudinal lines or furrows ; beak slender, elongated, sinuous. 



Subgenus AFER. 



Fusus bellaliratus. PL 35, fig. 17. Fusiform, spire prominent, acute ; volutions 

 of spire seven, subscalariform ; tuberculated inferiorly and ornamented with revolving 

 lines ; body volution ribbed longitudinally, and having prominent transverse, robust 

 lines, which on the ribs assume a tubercular aspect ; beak elongated. 



This shell is referred to a subgeneric division of which Fusus afer, Lam., may be 

 regarded as the type. 



PYRIFUSUS, Ocmrad. 



Pyriform; columella broad, thick, flattened; body volution transversely oval. 



Pyrifusus subdensatus. PI. 35, fig. 12. Subpyriform ; spire short, subscalariform, 

 volutions four ? longitudinally ribbed and spirally lineated, lines minute ; body whorl 

 wide, contracted above where there are longitudinal wrinkles and revolving lines ; below 

 are prominent ribs becoming obsolete about the middle, and prominent, revolving 

 lines over the whole surface below the shoulder. 



FICUS, Klein. 



Ficus octoliratus. PI. 35, fig. 6. Pyriform; spire conical ; costaeof body volution 

 about eight in number, inclined to be square, distant ; beak long and slender. 



RAPA, Klein. 



Rapa supraplicata. PL 35, fig. 20. Pyriform ; spire depressed, volutions flattened 

 above ; summits ornamented with oblique, curved strias or grooves. 



A very much broken specimen, but the fragment exhibits marked characters. It 

 is a very ventricose, smooth species, easily recognised by its flattened volutions and 

 curved lines.
