generic name, Huronia, and assigned specific names to the five ^ 
species which Bigshy had separated on “variations of external 
form’’. Stokes recognized the other cephalopods in Bigshy ’s 
paper as “ Orthocerae ”, hut no names were suggested. 
It may he of interest at this point to recall that Drummond 
Island was formerly the site of a British garrison and fossil re- 
mains were first collected there by a Mr. White of the Army 
Medical Staff. By the treaty of Ghent the island was ceded to 
the United States and the British garrison was withdrawn. Dr. 
Bigshy, an ardent Englishman, laments in his paper, page 202, 
that “as it will not he held as a military post by its present 
owners, it will be long, probably, ere its fossils again become the 
object of research.” Fourteen years, however, after the reading 
of Bigshy ’s paper, Stokes read an article before the same society 
“On some Species of Orthocerata”® in which he corrected his 
former view as to the coral nature of Huronia and interpreted 
the fossils as the siphuneles of orthoceracones. 
It would extend this paper to an unwarranted length were the 
writer to mention, even briefly, the work of later geologists and 
paleontologists who have contributed to our knowledge of the 
Niagaran cephalopods. Keference will be made to a few of them 
in the descriptions which follow but no attempt will be made to 
give a complete bibliography of each species. 
For the sake of taxonomic clearness it may be stated here that 
Hyatt® makes Huronia a sub-genus of Actinoceras while East- 
man in the second edition of Zittel’s Textbook of Paleontology, 
1913, page 609, treats it as a genus of equal rank with Actinoceras 
in the family Actinoceratidae. The latter will be followed in 
this paper.
