570 THE AMERICAN NATURALIST [Vol. XLII 



posed, instead, to call attention to a few of the most in- 

 teresting finds of this year, especially those which can 

 readily be illustrated by photographs. Most of the work 

 this year was done at what we call Station 13 B, close to, 

 and apparently of the same materials as, Station 14, from 

 which the best things of former years have nearly all 

 come. Superficially, 13 B seems to dip under 14, but this 

 appears to be due to a fault; both beds belong to the 

 older series of the locality, being covered by extensive 

 deposits of rock and shale, the greater part of which, at 

 13 B, has been removed by erosion. 



The shale at 13 B proved extremely uneven in quality. 

 During the first week the results were perhaps better than 

 in any week of former years ; but the last two weeks were 

 relatively barren, and, as we were getting a large propor - 

 tion of duplicates, it was doubtful whether the work justi- 

 fied the expenditure. It is highly important, of course, 

 that the Florissant beds should be further explored, and 

 no doubt the treasures yet to be uncovered there are in- 

 numerable ; but with limited resources, and great accumu- 

 lations of unworked materials on hand, it has seemed 

 better not to continue digging at the present time. 



At the University of Colorado an exhibit of the Floris- 

 sant fossils has been arranged. It is probably the best 

 in existence, although the insect specimens in the Scudder 

 collection at the Museum of Comparative Zoology, none 

 of which are on exhibition, far exceed ours in number 

 and variety. From {he recently gathered materials, a 

 series will be prepared for Colorado College, and also 

 one to be sent to Dr. E, F. Scharff, for the Dublin 

 Museum. 



The members of the 1903 expedition were the same as 

 m 1907, with the addition of Mr. Melford Smith, and, 

 for a shorter time, Miss Gertrude Darling. 



The Fish-genus Tkichophanes 

 In 1872 Cope published Trichophanes, a new genus of 

 Perciform fishes, represented by a small specimen ob- 

 tained m the coal shales north of Osino, Nevada. In 187?
