Onion Point, Lake Manitoba, J. B. Tyrrell and J. F. Whiteaves, 1888 : 

 four specimens. A few characteristic examples of tliis species also were 

 collected by Messrs. Tyrrell and Dowling in 1889 at each of the following 

 localities . Lake Winnipegosis, at the north end of Snake Island, at a 

 small island off Weston Point, on the north, south-east and south-west side 

 of South Manitou Island and at Point Brabant ; on the south-west side 

 of Cameron Bay, and in Dawson Bay on a sn)all island to the south-west 

 of Whiteaves Point, at Point Wilkins, and at the head of a small bay 

 south of Point Wilkins ; at the C. P. R. crossing of Mossy River, Man. ; 

 ■on the Red Deer Ri\er at its mouth, and at the Lower and Upper Salt 

 springs ; at Rosebush Island in Swan Lake, and at the lowest crossing of 

 the Swan River ; also, Ioosi>, on the east side of Lake Winnipegosis, at a 

 small island east of the south point of Birch Island. 



In this district only one specimen of C. Hniiii]tonpnsii< has been found 

 in the Stringocephalus zone, but it appears to be everywhere abundant 

 throughout the Upper Devonian.

Warren Island (possibly the Rose Island of Mr. Tyrrell's map), Swan 

 Lake, Manitoba, J. W. Spencer, 1874 ; six specimens. 



Dawson Bay, Lake Winnipegosis, in the Upper Devonian rocks at Point 

 Wilkins, and at an exposure about two miles south of Point Wilkins ; 

 also on Rose and Hog Islands in Swan Lake, J. B. Tyrrell and D. B. 

 Dowling, 1889 : apparently not uncounnon at each of these localities. 

 Most of the specimens collected are nearly perfect, but none of them 

 show any of the characters of the interior of the valves. The mesial fold
