VOL. XXIX. 



ORTHOGONOPHORA, r\e\!v genus. 

 ORTHOGONOPHORA DISTINCTA, new species. 



Locality. — Dnnvs ('reek, West Viriiiniii. Coal 

 Measures. 



A small piece of a inediuin-sized wing-, permit- 

 ting the recognition of the end onl}' of the simple 

 radius, a portion of the radial sector with its 

 last short l)ranch, and the ends of 8 other almost 

 parallel veins curving toward the inner margin; 

 the latter certainly belong to the radial sector 

 and to the media. All these veins are united by 

 conspicuous, straight, vertical cross veins. 

 This fossil, also, most probably belongs to the Paheodictyoptera, 

 but is too imperfectly preserved to be more accurately determined. 

 IMotypc.—Odi. No. 25632, U.S.N.M.

BATHYTAPTUS, new genus. 

 BATHYTAPTUS FALCIPENNIS, new species. 



Locality. — Coall)urg, near Birmingham, Alat)ama. Upper Potts- 

 ville; Pratt group; probably Sewell stage. 



The tip of a larger wing, whose sinuate lower border and straight 

 costal margin somewhat recall 

 Breyeria. The subcosta is pre- 

 served nearly to the tip of the 

 wing and fuses in the costa. 

 The radius is simple and runs 

 parallel with the sulx-osta. The 

 radial sector, which is separated 

 from the radius l)y a wide area, 

 sends out its partly dichoto- 

 mous, partly simple branches, 

 obliquely backward. Delicate, 

 somewhat undulating, and occa- 

 sionallj' branched cross veins 

 unite the longitudinal veins, but form no network. 



In some points this fossil recalls the European breycriids, but foi' 

 the present can not be placed with certainty in any family. Doubt- 

 less, however, it ))elongs to the Paheodictyoptera.
