234 Hill—Outlying Areas of the Comanche Series, ete. 
These beds represent the modified attenuated northern ex- 
tension of the Washita division and probably a portion of the 
Fredericksburg division of the Comanche series of Texas, 
which, as we have previously shown, far overlapped to the 
northward those of the Trinity division. The beds of the 
later division have not been found north of the 34th parallel 
and there is every reason to believe that their original sedi- 
mentation did not extend north of this line. Neither are the 
remarkable limestones and accompanying forms of the great 
Caprina limestone of southern ‘Texas represented in the outly- 
ing areas.
