Several specimens of this species were collected at Lower Fort Garry 

 by T)r. R. Bell in 1880, and by T. 0. Weston in 1884. At East 

 Selkirk, in 1884, Mr. Weston obtained an unusually large ventral valve 

 of S. incurvata, which is about seventy millimetres broad at the hinge 

 line, and forty-four mm. long. On Lake Winnipeg the species has been 

 collected at Kinwow Bay, and at Birch or Inmost Island, in Kinwow 

 Bay, by T. C. Weston in 1884, and by D. B. Dowling and L. M. Lambe 

 in 1890; also at Cat Head and Big Sturgeon Island by D. B. Dowling 

 and L. M. Lambe in 1890. 



Characteristic examples of jS'. incurvata had previously been collected 

 by Dr. R. Bell in 1879, on the Nelson River, Keewatin, at the Lime- 

 stone Rapids, 100 miles up, at the second and third rapids, and at the 

 first Birch Brook. Some of these are referred to, under the name 

 Strophomena filitexta, Hall, on page 470 of Appendix 1 to Dr. Bell's 

 Report, in the Report of Progress of this Survey for 1878-79.
