Snake Island, Lake Winnipegosis, Prof. H. Youle Hind, 1 S.^)S : one 

 specimen. The species has since been collected by .Messis. Tyrrell and 

 ])owling in 1889 at the following localities in, on or ncai- Lake Winnipe- 

 gosis. On Charlie and Snake Islands, at the S(juthern extremity of the 

 lake ; on a small island off M'eston Pnint ; on Snuth Manitou Island ; at 

 Point Brabant ; on the south-west side of Cameron Bay ; in I)awson Bay, 

 on the second small point east of the mouth of Bell liiver ; and on the 

 Bed Deer Eivei', a mile above the Lnwcr Salt Spring. A few specimens 

 of a shell which apipears to be an unusually slender variety of 0. JImdii, 

 were obtained by Mr. Tyrrell and the writer, in ISSS, at (Jnion Point, 

 Lake Manitolja, 



Although slightly enlarged between the s(qita, the siphuncle of this 

 shell is not nunnnuloidal as in Acfiiiin-crKs, nor e\en distinctly moniliform 

 as in Sac/oci'i-iis. The characters of the species, therefore, set'in to accord 

 better with those of Oii/ioci'vus as desoril)ed by most paheontologists 

 (though perhaps not as restricted by Hyatt) than with those of Actimicrras 

 or Bactor.eras.
