Eocky Spring Eidge, near ilticLeod Bcntoii Trail, G. 31. Dawson, 

 1881 ; apparently rather abundant. "West flank of AVest Butte, Mon- 

 tana, but close to the Forty-ninth Parallel, G. M. Dawson, 1881. 



These fossils evidertly belong to the same species as those from Mon- 

 tana which Mr. Meek referred doubtfully to the B. asper of Morton. 

 The most perfect of the sj)ecimens collected by Dr. Dawson is .slender, 

 with an ovate section, and measures about five inches and a half in 

 length. It tapers very gradually and, as Mr. Meek observes, " is orna- 

 mented on each side, near the antisiphonal margin, both on the septate 

 and non-septate portions, by a row of rather distantly ~-opavated, node- 

 like prominences, that show the faintest perceivable tendency to ex- 

 tend oblifj^uely forward and towai'd the sipihonal side, as undulations, 

 pai-allel to the lines of growth."

\\'est flank of AVest Butte, Montana, near the Forty-ninth Parallel, 

 G, M. Dawson, 1881 ; abundant but usuall,y imperfect and badly pre- 

 served. One of the specimens from this locality, however, i^ nearlv 

 ]ierfect and corresponds almost perfectly with Mcek's tiguj-cs of the 

 variety Wi/omingensis, and two others although immature arc well 

 preserved and very little broken. Eocky Spring Eidge, near MacLeod 

 Benton Trail. G. M. Dawson, 1881: four specimens.
