Neocene by Dr. Win. H. Dall and G. D. Harris.* These authors review 

 at length all fossil-bearing horizons in Alaska, and on a map accom- 

 panying the work have colored each locality geologically. They speak 

 of plant beds in various places. 



Herendeeu Bay, the locality attbrding the specimens that form the 

 basis of this paper, is on the northern side of the Alaskan Peninsula 

 and forms a branch of Port Moller (Lat. 55° 40', long. 100°, 40' ±.) 

 The plants were collertcd July 28, 1890, by Mr. diaries H. Townsend, 

 resident naturalist of the U. S. Fish Commission Steamer Albatross. 

 Mr. Townsend has furnished tlie following co^)y of his notes relating 

 to their occurrence : 



July 28, 1890. — In making a tramway to the new coal mine jnst opened here (Heren- 

 deen Bay), one of the slaty cuttings exposed a largo deposit of fossil leaves and ferns, 

 about a mile from the beach, at the head of a little valley among the hills and within 

 a few hundred yards of the mine itself. We visited the place twice and succeeded 

 in getting a considerable (niantity of specimens. Coal veins crop out in several 

 places in the region of this bay. The first output of the new mine is now being used 

 in the furnaces of the Alhatrons, but it is from near the surface and rather slatv. 



Mr. Townsend further adds: 



The country is mountainous and treeless, but covered with bushes and smaller 

 vegetation. It is iu general volcanic and there are lofty peaks, one of which, Par- 

 loff, has been seen smoking. 



The material in which the plants are preserved is a fine argillaceous 

 sandstone, very well fitted for retaining the impressions. The vegetable 

 remains are in most cases very numerous, even on small fragments of 

 matrix.

The specimens at Heer's disposal were not regarded by him as of 

 sufficient distinctness to permit of specific determination. He remarks 

 that it appears very similar to C. liasiitas of the Swiss Tertiary, and also 

 resembles forms in the Trias and especially C. Targionii of the older 

 Molasse. Eichwald, however, had secured better material and took 

 the opportunity to confer Heer's name upon it. Eichwald's specimens 

 were preserved on the same kind of dark carbonaceous shale as Taxo-
