always clearly separated from each other, linear to narrowly 
ovate-lanceolate. The venation is indistinct. The midvein of 
the ovate pinnules enters the lobe near the lower side, gives off 
one or two veins from either side and divides somewhat above 
the middle of the pinnule. The veins are few and rather dis- 
tant. 
Pecopteris germart (Weiss) F. and I. C. W., which has a 
frond with divisions similar to this species, lacks, as indicated 
by Weiss,?*! as well as by Fontaine and White,?®? the winged 
character of the rachis. The species has much in common 
with Pecopteris beyrichi (Weiss) Zeiller. 
Many of the specimens are thickly set with the supposed 
fungus H'xcipulites neesti Goep. 
Formation and locality: Chanute shales, Thayer, and Le 
Roy shales, Lawrence. Mr. David White records the presence 
of this species in the Cherokee shales at Lansing (Bull U. S. 
Geol. Surv. No. 211, p. 110, 1903).

This species is present, although not common, at the State 
Penitentiary mine, at Lansing. A few good typical specimens 
have, however, been obtained. 
Formation and locality: Cherokee shales, Lansing.

A single specimen from Lansing is referred doubtfully to 
this species.
