1042 General Notes. [ December, 
the Harpes was described originally from the Trenton. About 
the specific identity of the latter there is yet some doubt. 
Besides the fossils already mentioned, the paper also includes 
descriptions of another new genus of gasteropod—Calaurops 
(a shephed’s crook), for a form collected in a bed some twenty- 
five or thirty feet below and just above the Maclurea bed, having 
the form of a Euomphalus in the inner coils, but afterward be- 
coming deflected in a straight line to the extent of six inches. 
Also two Trilobites and a Cyrtoceras from the Birdseye of Isle La 
Motti. 
Since the meeting at Buffalo and during the week previous, the 
author of the paper, in conjunction with the persons named in 
the title of the paper, have made other collections at the same 
locality, which has resulted in the discovery and determination of 
several other species, the descriptions of which are nearly ready 
for the press, and illustrations of them for the engraver. The 
fauna of the Birdseye limestone at that locality is known now 
to consist of the following group of fossils:
