164 DESCRIPTION OF SPECIES. 



or Ungulate, rounded at the base and apparently at the apex also; they 

 vary in size from 10 to 20 centimeters long and from 3i to 6* centimeters 

 broad in the middle. Fig. 2 may represent a difterent species not merely 

 on account of the different size, but from the presence of tertiary thinner 

 and shorter veins intermediate to the secondary nerves.

Ficus teimiuervis, ep. nov. 

 Plat« XLIV, Fig. 4. 



Leaf oblong or lauceolate, tripalmately nerved, rounded at base, entire. 



A mere fragment, showing the lower part of a leaf whose lower lateral 

 nerves are strongly branched downward and all (nerves and branches) 

 camptodrome. The medial nerve is inflated at base. The fragment rep- 

 resents a Ficus, but the specific characters are not discernible.

Ficus alkaliua, ep. nov. 

 Plate XLIV, Figs. 7-;i. 



Leaves thin, variable in size, obovate or ovate-lanceolate, acuminate, obtusely 

 serrulate, palmately trinerved; secondary nerves distinct, all camptodrome, alternate 

 and parallel; nervilles oblique, simple or forking in the middle. 



The leaves are fragmentary, variable in length from 6 to 10 centi- 

 meters, and proportionally broad. The nervation is that of a Ficus; the 

 lower primary lateral nerves are thin, flexuous, ascending at a more acute 

 angle of divergence. The upper are parallel, camptodrome, attached to the 

 teeth by small anastomosing nervilles.
