384 GEOLOGICAL SURVEY OF THE TEEEITOEIES. 



Oaulinites fecunda, sj). nov. 



Branches of racemes, 2 mill, wide, smooth, with inflated borders, 

 divided in opposite erect branchlets, half as thick, bearing on each side, 

 and on short pedicels, simple round capsules, with a central nucleus. 



The capsules are mostly opposite, rarely alternate, and close to each 

 other along the branchlets. One of these, 2 cent, long, bears twelve of 

 these capsules on each side. They are 1^- mill, wide; the black nucleus, 

 slightly smaller, is represented by a vesicle of coaly matter easily sepa- 

 rated from its envelope, slightly narrowed, however, toward the top of 

 the small pedicel, which is slightly inclined from the main rachis. 

 These racemes may represent the female infloresceme of some dioecious 

 species. Their relation to species of our time is as yet unknown. The 

 same sjpecimen which bears this species has, too, some nutlets of larger 

 size, oval, truncate at base, wrinkled in the length, apparently in 

 racemes or agglomerations, resembling those which have been published 

 by Ludwig in Pal., vol. viii, PI. xliii, Fig. 13, under the name of 

 J3y2);popJiae striatii. 



Caulinites sparganioides, sp. nov. 



Described with better specimens from Black Butte. 



PlCU§ PLANICOSTATA, sp. noV. 

 Yar. LATIFOLIA. 



Described, like the former, with specimens of Black Butte. 



Paliueus zizyphoides, sp. nov. 



Described from Black Butte's specimens. The leaf from Erie is only 

 smaller. 



JUGLANS SCHIMPERI, Lsqx., Supt., p. 8. 



The leaf is of larger size than that from Green River Station, but has 

 the same characters. The same specimen bears on the reverse a fine 

 oval flattened nut, with an irregularly wrinlded surface like the nut of 

 a Juglans. It is 26 mill, long, 18 mill, broad, slightly pointed on one 

 side, and abruptly contracted at the other to an obtuse protuberance. 

 The only fruit com^iarable to this is that of Juglans venosa, Gopp, as 

 figured by O. Weber in Pal., vol. viii, PI. vi, Fig. 11. The specimens 

 from this localitj- are as yet too scanty to allow a conclusion of identity 

 between this fruit and the leaves described as Juglans Schimperi. 



Ceecis Eocenica, sp. nov. 



Leaf nearly round, entire, of a thin texture, smooth surface, deeply 

 cordate at base, nervation of Cercis Canadensis. 



The leaf has its point destroyed ; it is apparently obtuse or round. 

 Except that it is more deeply cordate than the average leaves of our 

 Cercis Canadensis, tliere is no difference whatever between the fossil 

 leaves and those of the living species.
