but badly distorted and much less perfect specimens, which are probably 

 referable to the same species, were collected by Mr. Weston at Dog Head 

 (a little farther to the south-east), also in 1884.

Lower Port Garry, T. C. Weston, 1884 : a single specimen, with the 

 test preserved, which seems to agree better with the description and 

 figures of this eastern species, than with those of the nearly related 

 Trochonema (Eunema) Salteri of Ulrich and Scofield.* The spire of this 

 specimen is comparatively high and narrow, and the transverse lines of 

 growth on the dorsal surface of the outer volution are nearly straight, 

 but curved shghtly forward at the base. 



Sdbulites. (Species uncertain.) 



An imperfect cast of the interior of the shell of a small and very 

 slender species of SubuUtes, which is similar in shape to the S. pergracilis 

 of Ulrich and Scofield, f but which shews no evidence of a sutural baud, 

 was collected on the west shore of Lake Winnipeg, north of the Sas- 

 katchewan, and opposite the north end of Selkirk Island, by D. B. 

 DowUng in 1891.

Casts of the interior of shells of this species are abundant at many of 

 the limestone exposures in the Red River Valley, on the western shore 

 of Lake Winnipeg, and on some of the islands in that lake. Specimens 

 of it have been collected by Mr. Weston in 1884 at Lower Fort Garry ; 

 at Bull's Head, Dog Head, Big Grindstone Point, Big and Elk islands, 

 Lake Winnipeg; by Mr. Tyrrell in 188 9, at Little Black Island; by Messrs.. 

 Dow ling and Lambe in 1890 at Little Black, Snake and Black Bear 

 islands; by Mr. Dowling in 1890 at Commissioners and Punk islands; 

 and by Mr. Lambe in the same year at Dog Head.
