In the Peter Redpath Museum at Montreal there is an imperfect and 

 badly preserved specimen of this species, which is labelled as having been 

 collected at Lower Fort Garry by Professor J. H. Panton. The only 

 other Canadian specimen of I. lowensis that the writer has seen is th& 

 "weathered section through a specimen" from "the Trenton limestone at 

 Ottawa," represented by fig. 364 on page 385 of the first volume of the 

 " Palseozoic Fossils," which is still preserved in the Museum of the Survey.

A few specimens which can scarcely be distinguished by any external 

 character from the types of Pasceolus gregarius in the Museum of the 

 Survey, or from Cyclocrinus Spaskii, as figured by F. Boemer, in the 

 Atlas to the first volume of the Lethsea Geognostica, were collected at 

 Lower Fort Garry, at Dog Head and Inmost Island, Lake Winnipeg, 

 by T. 0. Weston in 1884 ; at Jack Head Island by D. B. Bowling 

 and L. M. Lambe in 1890 ; and on the west shore of Lake Winnipeg 

 north of the Saskatchewan and opposite the north end of Selkirk Island 

 by D. B. Dowling in 1891. Most of the specimens are mere casts of the 

 interior of the organism, which shew nothing of the minute structure. 

 One specimen has a portion of the thin investing integument preserved, 

 but it shews only a transverse section of the integument, the outer 

 surface being completely covered by the matrix. The casts are small 

 sphserical bodies, about an inch in diameter, and marked externally with 

 numerous minute hexagonal facets, about one millimetre in diameter. 

 In some these facets are slightly convex, with a narrow flat border, and 

 indications of a small tubercle in the centre of each, when examined 

 with a lens, but in others the outer margin of each facet is raised and 

 the central portion depressed. 



It would seem to be doubtful whether Pasceolus gregarius can be satis- 

 factorily distinguished from Cyclocrinus Spaskii, especially in view of the 

 facts that the types of the former are from the Island of Anticosti, and
