and noduloso ; sulci in peculiar il;it grooves: ribbed Icngtliwise, 

 with short interui»ted costae, whorls convex, angulate above, 

 terminated by a long open graceful canal. 



This beautiful fossil is very near to Fiisus acris (Reeve and 

 Adams) of the China seas, and F. lon(jirostris of the Vienna 

 basin. If many of each species were put together I have no 

 doubt gradations from one to another would readily be traced. 

 They may be identical. Many miocene forms exist still 

 in China, and some of the European types closely approximate 

 to those living in the Eastern seas.

N. shell canaliculate ly-umbilicate, obliquely globose, 

 concave beneath, rather solid, spire elongate, whorls rounded, 

 apex acute, very delicately striate, aperture lunately-ovate, 

 columnar callosity small and only slightly entering the 

 umbilicus. 



This fossil I have dedicated to Mr. Wiutle, who has long 

 and industriously worked amid the Tasnianian rocks. 



Natica Polita, U.S., iV". testa parva, nitida, ventricosa, sub- 

 qJohosa, umhilicata, fragili, levigata, transversim suhstriata, 

 long, lineis ohsoletis fasciata ; anfractibus 5, siibr/lobosis,ad sutur.

 sinistro rejlexo, dextro tenul acuto. Anf. 5. Long. 13. Lat. 11. 



N. shell small, shining ventricosely sub-globose, umbilicate, 

 fragile, smooth or transversely substriate, banded with obsolete 

 lines, suture profoundly canaliculate, aperture ovately semi- 

 lunar, left margin reflexed ; right thin acute. 



This shell is very different from any existing or extinct 

 species, coming nearer to some European Eocene fossil forms 

 than any other.

 iitriiiquc suh-atteniuita, antice subrostrata, postice attenuata, utriusque

C. shell ovately oblong, smooth, inflated, somewhat attenuate 

 at each end, slightly rostrate above, attenuate below, 

 cmarginate ^at both ends, spire not quite covered, aperture 

 broader towards the base and furnished on both lips with 

 numerous sub-equal teeth. 



This fossil is not very different from C. sanr/uinolcnta 

 Gmelin (in Lin. Syst. Nat., p. 3406, N. 38) which is found in 

 the miocene faluns of Touraine and in the Vienna basin. 

 Compared with Huidinger's figures, the difference is slight,
