FROM THE TERTIARY OF VIRGINIA. 271 



Shell ovate, somewhat fusiform, thick, smooth, polished; spire ovate, very obtuse, rather short; sutures linear; 

 whorls four, flattened; last whorl rounded; base smooth; mouth sinuose, narrow; columella angled; canal long, 

 twisted. 



Length .08. Breadth .05 of an inch. 



Remarks. This minute species is remarkably ovate. The canal is very long, and 

 bent at several places. The apex is obtuse and sub-mamillate. 



This shell, most probably, attains a greater size than that mentioned above, as the 

 only specimen in my possession, bears evident marks of having had part of the last 

 whorl broken off. This may also have given it its peculiar twisted canal.

Shell ovate, sub-fusiform, perforate, thin, smooth, polished; spire sub-ovate, elevated, acute; sutures excavated) 

 wide; whorls five, convex; last whorl rounded; base smooth; perforation smalj, narrow; mouth sub-elliptical; colu- 

 mella short, twisted; canal long, very shallow, bent backwards towards the left. 



Length .18. Breadth .10 of an inch. 



O 



Remarks. There is a small canaliculation on the whorls near the upper part, which 

 makes the sutures quite wide and deep. The umbilicus is very narrow, and almost 

 hidden behind the columella. The canal is very peculiar, being folded round the base 

 of the columella, until it extends nearly a third round the shell. There are faint traces 

 of transverse striae to be seen on some parts of the whorls. 



It is not without some hesitation that I place this shell among the Fusi. It has not 

 the straight deep canal which usually characterizes that genus, but in other respects it 

 approaches it more nearly than any other. It may, perhaps, prove the type of a new 

 genus.

Shell ovately fusiform, thick, imperforate, striate; spire elevated, scalariform; sutures impressed, deep; whorls , 



somewhat convex, angulate at the upper suture; striae transverse, double, numerous, small; last whorl rounded, with 

 large and small alternating striee below; base longitudinally sulcate; mouth quadrangular; canal long, retorted; colu- 

 mella flexuose, with one large fold below. 



Length . Breadth 1.40 inches. 



Remarks. On the upper part of the last whorl the stria3 are in pairs with a minute 

 impressed line between them having the appearance of double striae. These, as they 

 approach the base, pass gradually into alternating ones. The base, immediately behind 

 the lower part of the columella, is marked with deep, somewhat semicircular, sulcations 

 pointing the successive growth of the canal. The upper part of the columella is marked
