of Natural History, and these specimens were kindly placed at the 

 author's disposal for study, by Prof. R. P. Whitfield. To these gentle- 

 men, therefore, paleontology is indebted for rendering it possible to 

 describe one of the best collections of fossils made in Arctic regions. 



With the aid of a camera lucida, Mr. E. O. Ulrich, of Newport, 

 Kentucky, made the figures, which are accurate representations of the 

 species. The author is further indebted to him for paleontological 

 assistance, and his various notes are incorporated in this paper in 

 their proper places. 



DESCRIPTION OF LOCALITIES. 



FroMsher Bay. — Previous to 1897, all that was known of the geology 

 of Frobisher Bay was included in a few incidental notes by Charles 

 Francis Hall.' His collections were partly studied by Mr. R. P. 

 Stevens^ and Prof. B. K. Emerson. •' 



During the months of August and September, 1861, Hall, in com- 

 pany with Innuit men, women, and children, explored, by means of 

 whale boats, the greater part of Frobisher Bay, which up to that time 

 was believed by civilized man to be a strait. On this trip he was also 

 greatly rejoiced to find unmistakable evidence of Frobisher's visit of 

 1556-57. The book cited is interesting reading, and from it are taken 

 the following notes regarding the geology of this Bay. 



Jones Cape. — Hall "ascended a mountain in the rear of our encamp- 

 ment. * * * On my way I observed a considerable quantity of the 

 stone I had noticed upon Iron Island, and I also saw many small pieces 

 of limestone on the very summit about a thousand feet above the level 

 of the sea." ^ 



This may be the locality which furnished the fossils from the Utica 

 stage, described by Professor Emerson and listed beyond. 



Cape Stevens. — This locality is nearly 100 miles farther inland than 

 Cape Jones, and here Hall on the top of a mountain " found numerous 

 shells and fossils, some of which [he] brought away."^ 



This may be the locality furnishing the Trenton fossils described by 

 Professor Emerson and listed beyond. 



Silliman's Fossil Mount. — At this place fossils were first brought to 

 Hall by the natives. 



At my left, across the river, was a ridge of white, which I afterward named Silli- 

 man's Fossil Mount (thus named after Benjamin Silliman, jr., of New Haven, Con- 

 necticut. This fossil mount is on the west side of the termination of Frobisher Bay. 

 It is in latitude 63° 44', longitude 68° 56'), and behind it the unbroken front of a line
