slightly impressed. The lower surface is convex, umbilicus 

 small. The present specimen is a cast and shows no surface

Lophospira rectangularis sp. nov. 



Shell fairly large, with 5 volutions. Body whorl very large, 

 spire small. Last 3 whorls with sides parallel to the axis of 

 the shell. Aperture large, nearly circular. Upper lip nearly 

 straight, meeting the straight outer lip at an obtuse angle. 

 The inner and lower sides of the aperture are rounded. The 

 umbilicus is very small. 



All the specimens in the collection are casts of the interior 

 and do not show anything more than traces of the surface 

 markings. They were probably the same as in Lophospira 

 sabaobreviata.

Lophospira billing si sp. nov. 



Shell of 4 volutions, body whorl very large, spire low, whorls 

 angular, sloping gently from the suture to the keel. The under 

 side of the body whorl is rounded and strongly convex. The 

 umbilicus is small. The aperture is entire, the inner and 

 lower lips are rounded, the upper lip is straight from the 

 suture to the keel, sharply angulated at the keel and nearly 

 straight for a short distance below it. The surface is covered 

 by rather coarse lines of growth, which run first forward and 

 cross the upper side of the volution diagonally and backward, 

 again turning forward after crossing the volution. On the 

 under surface of the whorl, the stride turn back to the 

 umbilicus. 



Locality. — From the Canadian Pacific Railroad cut, east of 

 Main street, Aylmer, Canada. Named for W. R. Billings of
