It is interesting to find this genus in the fossil state. Compared 

 •with the living U. mediterranea, Lamarck, the Australian shell 

 is rather more elevated, is not so elliptical, and the inner radiating 

 striae are not as well pronounced in the neighbourhood of the 

 muscular impressions.

[Mem. Soc. Hist. Nat. Paris, 1799, p. 71.] 



Shell subulate, many-whorled, with a short anterior canal and 

 smooth columella. 



This genus has been divided into many sections, but the writer 

 agrees with Tryon^ that it cannot be advantageously dealt with 

 in that manner, though an exception may be permitted in the 

 case of the subgenus JEuryta. 



Type. — Buccinum suhulalum, Linnaeus.

Shell pyramidal, whorls flattened convexly ; " slightly over- 

 lapping ; double-banded and nodulose in front of the suture, the 

 posterior band rather the broader, and separated by a shallow 

 sulcus, in the centre of which winds a subangular ridge defined 

 by linear grooves; about 20 pairs of nodulations on the penultimate 

 whorl ; anterior half of each whorl distantly and superficially
