tion of the Allegheny formation on the Allegheny River, of western Pennsyl- 

 vania, present conflicting interpretations of the section, while adequate faunal 

 and floral data are lacking for the correlation of these deposits with those 

 farther east. The present paper is a contribution to a fuller knowledge of the 

 typical section of the Allegheny formation in the vicinity of Freeport and 

 Kittanning. Pennsylvania. 



STRATIGBAPHT AXD CORRELATIOX OF THE COAL MEASURES OF MARYLAXD 

 BY CHABLES K. SWAETZ. W. A. PRICE. JR.. AXD HARVEY BASSLER 



(Abstract) 



The senior author is alone responsible for the discussion of the stratigraphy 

 of the Coal Measures of Maryland. In the study of the correlation he has 

 secured the cooperation of "W. A. Price. Jr.. who has investigated the marine 

 faunas, and of Harvey Bassler. who has studied the Carboniferous floras. 

 The conclusions presented are based on the concordant evidence afforded by 

 the various lines of investigation. 



The stratigraphic sequence of the Coal Measures of Maryland will be given 

 the members, briefly characterized, and new limits will be assigned to certain 

 of the formations. Attention will be called to a series of persistent and recog- 

 nizable horizons in the Coal Measures of the northern Appalachians, which 

 can be traced from Ohio eastward to Maryland and furnish a basis for the 

 correlation of these beds throughout that area, including those of Maryland. 

 The occurrence and significance of systematic changes in thickness of the sedi- 

 ments, the development of coal beds, and distribution of red beds will be dis- 

 cussed.

EOCEXE DIYISIOXS OF CALIFORXIA 

 BY BRUCE L. CLARK 



(Alj-stract) 



There are at least three distinct stratigraphic units in the Eocene of Cali- 

 fornia. These, beginning with the lowest, are the Martinez, the Meganos. and 

 the Tejon. The Meganos Group, the newly recognized division, is separated 

 unconformably from both the Martinez Group and the Tejon Group and has a 

 wide distribution throughout the State. 



The fauna of the Meganos Group is very distinct from that of the Tejon and 

 that of the Martinez. It appears to be of the same age as the fauna found in 

 the Eocene sections at Marysville, Butte, and Table Mountain, near Oroville, 

 California. A portion of the Eocene, described heretofore as the uppermo.st 

 division, belongs in reality to the middle Eocene. The lone, as recognized by 

 them, is the equivalent of the Meganos Group. 



Further details are presented as to the stratigraphic relationship of the 

 Meganos and the Tejon of three sections in widely separated parts of the State.
