DESGRirTION OF SrECIES. 77 



scarcely curved in passing to tlie borders, joining' by abrupt curves, or 

 Avitliout curving to it, a somewhat thick, marginal nerve. 



The species is represented by niauy fragments ot" leaves, one ot" them 

 20"°' long, 7.5*"" broad below the middle. The nervation is of the t)'pe of 

 F. miiUinervis Heer, or F. parasitica Scliott, this last figured ])y self-imi)res- 

 sion in Foss. Fl. Bilin, pt. 1 , PI. xxiii. Fig. 1. Compared to fossil .species of the 

 Cretaceous of Greenland, it is like F. protofjcea^, or F. atavina Heer^. From 

 this last species it differs essentiallv by the large size of the very thick 

 leaves, is more rapidly narrowed to the l)ase and the lateral nerves, some- 

 times forking above the middle, abruptly anastomosing with a thick, margi- 

 nal nerve, which follows close to the borders, even apparently forming the 

 borders and thus genei-ally obsolete; for often this nerve appears as the 

 impression of the narrowly recurved margin. In the living species of Ficus 

 of this ty])e, this marginal nerve is often scarcely perceivable, and thus is 

 very rarely observed in the fossil leaves. The angle of divergence of the 

 nerves is about 60°. 



Habitat: Two and one-half miles south of Glascoe, Kansas. Nos. 478

Ficus proteoides, sj). uov. 

 PI. XII, Fig. 2. 



Leaves very hmg, coriaceous, entire, lanceolate, broadest in the lower 

 part, gradually nari'owed upward and gradually tapering to an obtuse apex, 

 more rapidly naiTowed toward the petiole; primary nerve strong, secon- 

 daries alternate, very thin, partly obsolete, curved in passing toward the 

 borders, camptodrome. 



The leaf, by its form at least, is much like those of Ficus rlnnr/ata 

 Hosius.' It is, however, longer, esi)ecially differing by the nmch thinner 

 secondaries being far more curved, and l)y a petiole only half as long. 

 The leaf is nearly 22™ long, 3'='" broad at its broadest part fi*^" above the 

 base, and witli a petiole 2'"" long. The thin secondaries are a little more 

 open than in /•'. Bcrihoiidl Lescj., more curved in traversing the blade and 

 shorter, or not ascending high along the border. It differs also fi-om 

 it by being enlarged nearer to the base, its borders rounding somewhat in
