DESCRIPTION OF SPECIES. 173 



researches; certainly tlic leaf from Kau8as, wliich is well jireserved except 

 the apex, is another species related merely by tlie areolation, the texture of 

 the leaves, and the character of the serrate borders to tlie leaf from Nieder- 

 schoeua, the teeth of wliich are, however, larger and more distant. 



Habitat: Ellsworth County, Kansas. No. 97 of the museum of the

Cret. FI., p. 108, PI. xxi, Figs. 2, 3. 



Celastrophyllum oretaoeum, sp. nov. 

 PI. XXXYIII, Figs. V2-U. 



Leaves small, thickish, entire, elliptical or oblong, obtuse, gradually 

 naiTowed to the base; primary nerve strong, percurrent; secondaries very 

 thin, mostlv obsolete, di.stant, parallel, very oblique, camptofli'ome. 



A number of leaves, all of small size, but of the same character, are 

 found preserved in nodules of the Dakota Group. They are somewhat 

 thick or of subcoriaceous texture, with borders reflexed, entire, varying in 

 size from 2™ to 4'^'° in length and from 9"'" to 12'"'" in width, the second- 

 aries being distant, parallel, slightly cuvved, diverging at an angle of 30° 

 to 35°. 



In form and size these 'leaves resemble those of fossil species of Celas- 

 trus, Andromeda, or Calistemophyllum, described by authors. On account 

 of their likeness to the "leaves of ditierent living genera, and the indefiuite- 

 ness of their nervation, they remain of uncertain relation. 



Habitat: Ellsworth County, Kansas. Nos. 643, (i99, and 703 of the 

 museum of the University of Kansas. Collected by E. P. West. 



Celas'I'kophyllum obliquum, sp. nov.' 

 PI. LVII, Fig. 5. 



Leaf small, coriaceous, apparentlv narrow from the round apex to the 

 base; midrili narrow, somewhat curved; secondaries very oldique, the 

 lowest apparently basilar, ascending parallel to the borders, anastomosing- 

 with those above by short branches at right angles. 



The leaf is partly obscured by the embedding stone and its borders 

 are not distinctly seen. The fragment preserved is 4"'" long and Lb""" broad
