570 General Notes. [ September, 
ice on the Labrador, apart from glacial sculpturing, appears to be almost 
altogether due to the periodical action of pan-ice deriving its power and 
- constant opportunities from the arctic current, which presses continually 
on the Labrador coast.” 
New Fossit Fisnes rrom Wyomine. — At a recent meeting of the 
American Philosophical Society, Professor Cope announced the discov- 
ery of a new locality of the Green River shales, containing fishes, insects, 
and plants in a good state of preservation. Owing to the rather soft 
nature of the matrix the characters of the fishes could be worked out 
with much nicety. A collection which he had recently received includes 
sixteen species of fishes, mostly new. Their names are as follows :— 
? Ohromidide: Priscacara serrata Cope; P. cypha Cope; P. liops 
Beanii Cope ; M. longus Cope. 
Asineopide: Asineops pauciradiatus Cope. 7 
? Aphredodiridæ : Erismatopterus Endlichii Cope; Amphiplaga bra- 
chyptera Cope. ; 
Clupeide : Diplomystus dentatus Cope; D. analis Cope; D. pectoro- 
sus Cope; D. humilis Leidy; D. altus Leidy. 
` Osteoglosside: Dapedoglossus testis Cope: D. encaustus Cope. 
the above genera all but two are new to science, and all of the 
species but three are likewise new. From the present collection some- 
thing like a general view of the ichthyological fauna can be obtained, 
since the predominant types are probably represented in it. Prisca- 
cara is a Pharyngognath allied to the Ohromidide and Pomacentride, 
most nearly to the former; and Dapedoglossus is not far removed from 
Arapema and Osteoglossum. The facies of the fauna is of a mixed 
character, both fresh-water and marine types being present. The largest 
species is the Osteoglossum encaustum; the second in size is the Diplo- 
mystus dentatus, which exceeds the,moss-bunker (Brevurtia menhaden). 
The species and genera are in process of publication in the Bulletin 
of the U. S. Geological Survey of the Territories. 
GEOGRAPHY AND EXPLORATION. 
Rise or Great Sarr Laxe. — While I was spending a few days 
in June last at Salt Lake, my attention was called to the evident rise 
in the Great Salt Lake, which had taken place since my last visit 
to the lake, in August, 1875. The point where I noticed the fact of 
a rise was at Farmington, Utah, where from overflowed salt vats that 
were above water in 1875, and from the wearing away of the shore, 
I roughly judged that the lake had risen at least twelve inches. 3r 
W. V. Haight, a farmer, who owns the land at the point visited, con- 
firmed my impressions. At Lake Point, twenty miles east of Salt Lake 
City, the captain of the steamer General Garfield informed me that
