TeLEOSTS FKOM KlSSELL SUBSTAGE. •)? 



19; averatje lenrjtli of vertebra' in mid-body G.l nun. (15 

 vertebra? included within 82 nun.) 



OccHvrence. — Benton stnuje of the Platte Cretaceous 

 series, iu the Downs limestone ("Fencepost limestone", or 

 "Postrock") of the Russell substa^e, near Bazine, Kansas. 



Bemarks. — The type and only known specimen of this 

 species was submitted to the writer late in the eighties by 

 Mr. Samuel G. Sheaffer, for study and to be placed in the 

 Museum of Washburn College, subject to return, if called 

 for. It has since been recalled by Mr. Sheaffer. On the 

 block containing it, is carved the locality record, "T. 19, R. 

 22, Sec. 3," together with the name of the probable former 

 owner or collector, "J. C. Long." For the photograph, from 

 which the illustrations have been made, the writer is indebted 

 to the kindness of Mr. Albert A. Blacknian. 



The species is readily distinguished from Pelecorapis 

 varius, as well as from all other known teleosts of the Platte 

 series, by the fineness of its scales, which is such as to give 

 the surface of the body a seedy appearance, the exposed parts 

 of the scales being only about as large as flax seeds, several 

 of them together covering only the area of a single scale of 

 the varius.
