WHITEAVF8. DEVONIAN FOSSILS OF MANITOBA, ETC. 336 



mere fragments, were obtained by Messrs. Tyrrell and Dowling, in 1889, 

 at many localities in, on or near Lake Winnipegosis, as, at the south end 

 of the lake, at an exposure two miles west of Meadow Portage, and on 

 Charlie Island ; on the south-west side, on a small island off Weston 

 Point and on South Manitou Island ; on the south-east side, at Point 

 Brabant ; and at the north-west end, in Cameron Bay and at five expo- 

 sures on the shores and islands of Dawson Bay ; also on the Red Deer 

 River, at and near the Upper Salt Spring. 



The exact number of volutions in the shell (.f this species is unknown, 

 as the upper part of the spire is broken off' in the mcjst perfect specimens 

 collected. Of the two specimens figured, one (tig. 8) has a considerable 

 portion of the test preser\ed on three contiguous volutions. The other 

 (fig. 9) is a cast of the interior of a shell of this species, which has been 

 slightly and abnormally compressed in such a way as to make the four or 

 four and a half volutions preserved, appear unusually broad in proportion 

 to their height. The actual height or length of this specimen is two 

 inches and three-quarters, and it is probable that when entire its height 

 slightly exceeded three inches. 



The preceding descripition will no doubt have to be somewhat amended 

 when more perfect specimens shall have been collected, but so far as can 

 be ascertained at present, this species of Lo.ronema seems to differ from 

 any of those from the Devonian rocks of North America, England or 

 Europe that the writer can find described, in its laterally flattened volu- 

 tions, crossed by densely disposed and nearly straight costuhe.

A few specimens of a small Loxoneniu, which agree very well with the 

 descriptions and figures of this species, were collected by J. W. Spencer 

 in 1874 on the west shore of Dawson Bay ("from slabs apparently 

 derived from the adjacent cliff's"); by J. B. Tyrrell and the writer in. 

 1888 from rocks in or nearly in place at Monroe and Pentanicrus Points,,
