edge, from one-fortieth to nearly one-tenth inch long, which are 

 arranged in series. The series are often terminated by pointed 

 bones (Fig. I, e.)

PALAEONISCVS antiquus. (N. sp.) Fig. 11, a. d. 



Scales usually rhomboidal, contiguous sides about one-tenth 

 inch each, posterior margin serrated, serratures three to ten in 

 number, serrature nearest upper margin often larger than the 

 others (Fig. II, b.) The middle of the upper margin bears a 

 short triangular process for articulating the scales together. 

 The surfaces are black, polished, and nearly smooth, ornamented 

 only by two fine lines about the anterior margin, and by a few 

 punctures. Some scales are of an oval form, prolonged above 

 into two diverging points (Fig. II, c.) No parts of this fish, ex- 

 cept the scales, have yet been discovered.

FISH REMAINS FROM THE CORNIFEROUS, NEAR 



BUFFALO. 



BY FRED. K. MIXER AXD HERBERT UPHAM WILLIAMS. 



It was long supposed that remains of fishes were extremely 

 rare in strata of the Corniferous period near Buffalo. The col- 

 lection of the Society of Natural Sciences contains a single 

 broken Ichthyodorulite. We have to report the finding of a 

 considerable number of specimens that must certainly be parts 

 of fishes, though they are not in a very perfect state of preser- 

 vation. They are still undetermined, and some of them will 

 probably prove to be new species. Among these fossils are 

 spines of several forms, scales, plates, and pieces of bone. We 

 hope to be able to identify them by the collection of more per- 

 fect ones of the same sort, and the results will be published in 

 this Bulletin.
