This paper contains many references to both the hard rock and the pebble 
deposits. The name Bone Valley Beds is proposed for the pebble phosphate 
deposits.

Reference to Florida occurs on page 80 and 115, where the “Archer forma¬ 
tion” of Florida (in part) is regarded as homotaxial with the Peraceras zone 
of the Ogalalla formation (upper part), which is regarded as the last phase of 
the Miocene or the first phase of the Pliocene.

The Alachua clays and Peace Creek beds are described in this volume 
(pp. 346-348, 366-368). In connection with the discussion of the Alachua clays 
it is stated, (p. 347) that Dali had found Pliocene beneath these deposits. [This, 
however, is an error, as Dali has not reported Pliocene beneath the Alachua 
clays. On the contrary he states that these deposits rest upon the Eocene and 
Miocene.]
