Zabechia Ohioends, Nicholson, is identical with Stenopora 

 Huronensis, and that the species ought to be called 

 Zabechia Huronensis. Most of the specimens of this coral 

 from Cape Smyth are large and some of them are massive, 

 but one encrusts a colony of Tetradiuni fihratiim and 

 another nearly covers a shell of Cyrtoceras Postumius. Of 

 the six specimens figured by Foord under the name 

 Tetradium Ruronense (op. cit., pi. 7), Mr. Lambe 

 finds that while fig. 1 represents a portion of a specimen 

 of Zabechia Huronensis encrusting Tetradium Jibratum, and 

 fig. la a portion of a massive specimen of Z. Huronensis, 

 that figs. 1, b-e are sections of Tetradium Jibratum, Safford. 

 A few specimens of Z. HuroneTisis were collected from 

 the Hudson Kiver formation at Club Island, Lake Huron, 

 by Dr. K. Bell in 1865, and from rocks of the same 

 geological horizon on the Credit Eiver at Streetsville, by 

 Mr. J. B. Tyrrell in 1888.

In his " Catalogues of the Silurian fossils of the Island 



of Anticosti," Mr. Billings says that this species was 



collected by Mr. James Kichardson in 1855, from the 



Hudson Kiver formation at Wreck Point, Salmon Eiver, 



and Battery Point, Anticosti, and from Division 1 of the 



Anticosti group at Macastey Bay. Specimens of the same 



Species in the Museum of the Geological Survey at Ottawa 



are labelled as having been collected by Mr. T. C. Weston, 



in 1865, from the same formation at and near the West 



end lighthouse, at English Head, and at Gamache (or
