fruiting- forms from our Coal Measures series may be made the subject of a 

 special stud.3-. 



A small and very fragile Aphlebia is presented at the base of the upper 

 pinna on the left of the specimen shown in PI. XX, Fig. 1.

 recent collection fi-om Pitcher's coal bank, U. S. Nat. Mus., 4468, 5565,

Oligocarpia ef. alabambnsis Lx. 



Although appearing to differ in some minor particulars from the char- 

 acters of Oligocarpia alahamensis as originally described by Lesquereux,^ 

 several specimens from Deepwater so strongly resemble others from Illinois 

 identified by that author as 0. alabamensis that I provisionally refer them 

 to that species, the type of which I have not seen. 



Locality. — Deepwater, U. S. Nat Mus., 5719. 



Oligocarpia cf. Gutbieri Goepp. 



The fragment which I temporaril}'- place among the specimens refen-ed 

 by Lesquereux to this species comprises about three-fom-ths of a compound 

 pinna, which, though a little larger, has the form and superficial characters 

 of the example from Illinois figured in the Coal Flora.- 



The specimen from Hobbs's bank is, however, preserved in a sandy, 

 micaceous shale that hardly permits a satisfactory analysis of the nervation, 

 which in the type from Illinois is very clear, the lamina being extremely 

 thin. Still, such traces of nerves as may be seen appear to agree with those 

 of the figured specimen, and although the lamina is dull and black in the 

 Missouri fragment, I think it probable that the plant should be referred to 

 the same species as that from Illinois. The latter, however, as illustrated in 

 the Coal Flora appears to diff'er from the type of Goeppert^ or Greinitz,* 

 some of the details of whose figures were copied by Lesquereux,^ by the 

 smaller, narrower, more oblique, and more deeply dissected pinnules, with
