shell a fluted appearance. In old shells these epidermal fringes are somewhat 
worn away, leaving the ridges upon which they stood. Greater diameter, 
5 mm. ; lesser, 44 mm. ; height, 15 mm. 
In some specimens as many as six teeth may be observed, none of which can 
be seen on the aperture. (Wetherby.)

The figure is drawn from one of Prof. Wetherby’s specimens. 
Ferussacia subcylindrica, Lixy. (p. 187.) 
To the synonymy add :— 
Cionella (Zua) Morseana, DouERTY, Quart. Journ. Conch., I. 342, Pl. IV. Fig. 2 
(1878). 
Pupa armifera, Say. (p. 205.) 
I am indebted to M. de St. Simon of Toulouse for a knowledge of the lin- 
gual dentition. There are 68 rows of 14—1-14 teeth, of which 7 on each side 
of the median line are laterals. 
Pupa contracta, Say. (p. 207.) 
To the synonymy add: — 
Pupa Cincinnatiensis, JopGEe, Quart. Journ. Conch., I. 348, Fig. (1878).

Vertigo ovata, Say. (p. 219.)

p. 53, Fig. Home and Science Gossip, Rockford, Illinois, March, 1881. 
An examination of the lingual membrane alone would prove this to be a 
Zonites. Until then I retain it in Vertigo, as identical with or allied to ovata, 
I have, however, on Plate I. Fig. L, given a copy of one of the original figures, 
leaving out the strise, which are exaggerated in the original, and here give the 
original description, from which the species may be recognized, should it prove 
a Zonites.
