quarters of an inch, in diameter, circular and annulated, with one or two 

 flat articulations usually alternating with a single raised and moderately 

 prominent one. In some portions of columns, however, from the same 

 localities, the raised articulations bear rounded and much elevated tuber- 

 cles. Both of the specimens are far too fragmentary to be identified, even 

 generioally, but they bear a striking resemblance to the C. decadactylus, 

 as figured by the Sandbergers, and to the C. (ijjnis, as figured by Zittel, 

 though some palaeontologists regard Ctenocrinus as synonymous with 

 2Ii'loci'inus.

Dawson Bay, Lake Winnipegosis, at a small island on the east side (one 

 specimen on a piece of a crinoidal column), and at Point Wilkins, on the 

 south-west side (several examples, attached to the shells of brachiopoda) ; 

 also on the Red Deer River, at the Upper Salt Spring, five miles from 

 Dawson Bay (one specimen on a simple Cyaihophyllum) ; J. B. Tyrrell, 

 1889. 



At each of these localities the specimens are rather more closely coiled 

 and consequently more narrowly umbilicated than the types described by 

 Goldfuss, but they agree very well with Ferdinand Roemer's figures of S. 

 omphalodes, on plate xxxi of the Atlas to the first volume of the Letluea 

 Gf,ognoHtii:n.
