'n-r.ujy' of the Upper Mi-.^olu■i Section. On similar evidence, also, the 

 rocks at the two localities on the \\alerton Eiver which have yielded 

 rcspectivelj' O.-^trea conijesta and Voh-icerainus ejvijyroides ; those at the 

 Highwood Eiver which contain Lioceramus midabundus and Scaphites 

 War/eni ; tho-e on the Northwe-t branch of the North fork of the Old 

 -Man Eiver trom which Inocerainus unilalnindui. Pholadoniya papyracea. 

 Srajjhites JJ'arrfni and S. ctrmifonnis were collected; ami those at the 

 entrance tii the Xnrth Kootanie Pass which are characterized bv Vol- 

 cir: ramus ejo^/i/roiiJes, SciAji/nte- W'trreni and ,S. cenniforniis, — wouh.l 

 apjjear tn be as nearly a- jmssible the Canadian equivalents of the 

 " Fort Benton Group." 



In conclusion, it may be I'emarked that las already partly stated 

 in the foot-note to page 55) the invertebrate fauna of the " Belly Eiver 

 Series" seems tn be essentially the same as that of the "Laramie" of 

 the United States and Canada, unless more than one formation has 

 been confounded under the latter name, and that it is at present 

 scarcely possible to separate the " Lower Dark Shales" of Dr. Daw- 

 son's Bow and Belly Eiver Eeport from the 'Tort Pierre and Fox 

 Hills " Grroups, on jjurely palapontological ground-~.
