On some remains of a Sepia-like Cuttle-fish from 

 THE Cretaceous rocks of the South Saskatche- 

 wan. 



By J. F. Whiteaves. 



In 1889, four rather remarkable fossils, which probably 

 represent the dorsal side of the internal shell or sepiostaire 

 of a new species of an apparently new genus closely allied 

 to Sepia, were collected by Mr. T. C. Weston, of the 

 Geological Survey of Canada, from the Montana or 

 Pierre-Fox Hills formation of the Later North American 

 Cretaceous, at the South Saskatchewan, opposite the 

 mouth of Swift Current Creek. 



Each of these fossils is imperfect posteriorly, and not a 

 trace of the mucro is preserved in any of them. The 

 most perfect of the four (which is represented, of the 

 natural size, in the accompanying plate), is about six 

 inches and a quarter in length by about three inches and 

 a quarter in its maximum breadth. It is elliptical or 

 elliptic-ovate in outline, slightly convex, but marked 

 with five narrow, acute, but not very prominent longi- 

 tudinal ridges, with rather distant, faint depressions or
