that they may prove to helong to Pinacofrypa, have been placed 
under the latter genus. Schuchert's Synopsis has been followed 
in the case of the Bvachiopoda. For the Corals Rominger's work 
on the Corals of Michigan and Hall's illustrations of Devonian 
Fossils have been carefully studied. Whiteaves's lists of Thed- 
ford fossils have been very helpful and his designations have been 
adopted in most cases outs'de of the Bryozoa and Brachiopoda. 
Grabau's Monograph on the Fossils of Eighteen-mile Creek has 
also been consulted. To the authorities already named should be 
added Billings's series of papers on the devonian fossils of Canaca 
West, published in the Canadian Journal in 1859 and 18()0. For 
the opportunity to examine these valuable and not easilv obtain- 
able papers the writer is indebted to the kindness of Rev. Hector 
Currie, of Thcdford, Ontario.
