Rainy Island : one fragment (Lambe). 



The types of Z. Stohesi are from Drummond Island, Lake Huron. In 

 Canada the species is recorded as having been collected from the Niagara 

 limestone at Cabot's Head, Georgian Bay, Lake Huron ; at Isle of Man 

 (Burnt Island) Lake Timiscaming, and at the north end of that lake ; 

 also from divisions Nos. 3 and 4 of the Anticosti group at four localities 

 on that island.

Seventeen to thirty 'miles below Rainy Island : one specimen, which has 

 been identified with this species by Mr. Lambe. 



This is the Silurian coral, with spiniform septa and mural pores in or 

 near the angles of the corallites, that Mr. Lambe identifies with F. Gbtli- 

 landica, and the same remark applies to all the specimens that are 

 referred to under this name in this paper. The Devonian specimens, 

 with septal squamul;e, that were identified with F Gothlandica by E. 

 Billings, Professor H. A. Nicholson, and the writer, are now referred to 

 F. basalticus (Goldfuss), F. Alpenensis, Winchell, or F. BiUingsii, 

 Rominger.

BRACHIOPODA. 

 Stropheodonta (Brachypeion) sp. indet. 



Rainy Island : a small single valve of a species apparently rather 

 similar to the fossil from the Niagara formation of the Western United 

 States which Hall refers to Strophodonta prnfrmda in the Twentieth 

 Regents Report, and figures on Plate 13 (4), but which Winchell and 

 Marcy seem to have previously described and figured as Sirophomena 

 Niagarensis. As Mr. Schuchert suggests that this western fossil may 

 not be the same as the eastern Rochester shale species, it will be con- 

 venient in this paper to refer to the former as Stropheodonta Niagarensis. 

 The valve from Rainy Island is moderately convex, and marked with 

 minute crowded radii, of two sizes, also with faint corrugations at the 

 hinge line.
