Washita. 
Since, therefore, in the Kent section, we have Prof. 
Marcou's G. dilatata, var. tucumcarii, in the same bed with 
such typical Cretaceous forms as G. pitcheri* Schloen- 
bachia leonensis, 8. peruvianus, Terebratula wacoensis, etc., it 
must here be considered a true Greta.ceous form. Its dis- 
covery in this connection simply adds one more to the list of 
fossils occurring in the Washita division of the Cretaceous of 
Trans-Pecos Texas, whose close resemblance to well-known 
*By G. tucnmcarii is meant the form figured by Prof. Marcou, 
Geology of North America, Zurich, 1858, PI. iv. fig. 3, and in Report of 
U. S. and Mexican Boundary Survey, PI. 21, fig. 3a, 3b, 3c. The G. 
pitcheri of this bed is the form figured by Prof. Marcou, loc. cit., PI. iv, 
figs. 5 and 6. The Texas Geological Survey has a large number of 
specimens of both species from the type localities, and typical speci 
mens are not to be confounded with each other or with other forms of 
Gryph;ea by any one at all familiar with them, although varietal forms 
of one may be indistinguishable from the other.
