Holoptychius serrulatus ? Cope 



E 2534 Impression of a scale and fin-rays. (Compare Smith 

 Woodward, Cat. Fos. Fishes Brit. Mus., II, pi. xi, figs, 

 ic, id; Cope, Proc. Am. Phil. Soc, vol. 36, pi. ii, fig. i.^^ 

 The tubercles of the covered area seem to be com- 

 pletely fused into ridges. Resembles H. serrulatus Cope, 

 but is smaller and lacks the cone-like tubercles of the 

 covered portion. It may, however, be a caudal scale 

 of this species as it came from the same formation and 

 locality as H. serrulatus Cope. 



Catskill; Seeley Creek, branch of Lambs Creek, 

 Mansfield, Tioga County, Pa. ; collected by W. L. Bryant.
