Mr. Schuchert has identified witli this species three specimens of a 

 coral which he collected in 189.5 from the " Middle third of the section" 

 near Thedford. These specimens, which the writer has examined, are 

 evidently conspecific with the coral from lakes Manitoba and Winnipe- 

 gosis referred to on page 272 of the fourth part of this volume as a 

 variety of Favoaites Gotldandica, Lamarck. The latter determination was 

 based upon the largely extended definitions of the characters of F. Gotlh- 

 landica, by E. Billings and Prof. H. A. Nicholson, and more particularly 

 on Mr. Billings's statements that the size of the tubes in the corals which 

 he refers to that species, " ranges from three-fourths of a line to a little 

 more than two lines,"*, and that "the spiniform rays (or septa) exist in 

 both upper Silurian and Devonian specimens of Favosite>;."j 



It is not clear to the writer why Dr. Rominger, in his monograph of 

 the fossil corals of Michigan, proposes to substitute the new name 

 Favosites Hamiltonensis for the F, Alpennnsis and F. dumo^us of 

 Winchell.

A common branching species, which was first recognized as occurring 

 in the Hamilton formation of Ontario by Professor S. Calvin. So far, 

 it has been found only in the " Middle third of the section," near Thed- 

 ford, and at Bartlett's Mills, where numerous specimens were collected 

 by Mr. Schuchert in 1895. The list of fossils of the Hamilton formation
