A CUCURBITACKOUS FRUIT FROM 

 THE TERTIARY OF TEXAS 



The large fruit which is the subject of the present contriljution 

 was sent to me in 192 1 by Professor O. M. Ball of the Agricultural 

 and Mechanical College of Texas, who obtained it from a student 

 who had picked it up on the surface in Foard County, in that 

 state. 



According to the geological map of Texas published by the Uni- 

 versity of Texas in 1919, the whole of Foard County is underlain 



Calcophysoides balli gen. et sp. nov. Nat. size 

 I. From side 2. From end 



by undifferentiated Permian. About fifty miles to the west of the 

 County the eastern boundary of the Cenozoic deposits of the Great 

 Plains province is placed. These last comprise the Panhandle 

 and Clarendon Miocene, the Blanco Pliocene, the Tule or Rock 

 Creek Pleistocene, and other unnamed deposits. Some of 

 these undoubtedly extend farther to the eastward than they 

 have been mapped, and it was from some such outcrop of un- 

 consolidated Tertiary, possibly of very limited extent, that tlie 

 present fossil was obtained.
