Highwood Pdver, ten miles west of first fork, E. G. McConnell, 1882 : 

 four fine specimens of an unusually large form of the species, the largest 

 of which measures nearly three inches in length, in the direction of the 

 longer axis of the ellipse, by about one inch and a half in its greatest 

 lateral diameter. Entrance to North Kootanie Pass, G. M. Dawson, 

 1S8.3: one specimen. ^Sovih West branch of ]Srorth Fork of the Old 

 Man Eiver, about four miles below Oyster Creek, G. M. Dawson, 1883: 

 an imperfect but large and very ventricose specimen, which is nearly 

 two inches broad although no pai-t of the deflected portion is preserved.

Xorth West branch of Xorth Fork of the Old Man Eiver, G. M. 

 Dawson, 1883 : two nearly jierfect specimens and two fragments. En- 

 trance to the Xorth Kootanie Pass, G. M. Dawson, 1882 : several large 

 fragments. 



These specimens appear to differ from those from the sauie localities 

 which are here referred to S. Warreni, in having the deflected portion 

 much shortei-. and in their coarser ribs, the larger ones of which usually 

 (though not invariably) bear a row of rather prominent nodes on the 

 outer half of each side. These nodes, however, are frequently not 

 developed, and it may be that the shells now under consideration should 

 be regarded as only a coarsely ribbed variety of ,S'. Warreni.
