authors aud probably younger, for it lies witli marked uncon- 

 formity on older rocks. The Galisteo sandstone of other authors 

 is evidently regarded as a part of Stevenson's "Laramie;" see 

 author's figure 40.) (Pp. 328-34G) Detailed descriptions and 

 sections of the coal-bearing rocks are given.

 The coal beds near Gallinas Mountains, New Mexico, are 



mentioned (p. 180) and a section farther north, including the 



coal measures, near the Colorado-New Mexico line, is described 



(p. 181).

(P. 42) In the table of formations' Puerco and Laramie are 

 included under post-Cretaceous, although it is stated (p. 4) 

 that the Puerco belongs to the "Tertiary rather than the post- 

 Cretaceous," and Fox Hills is' used as a group name to include 

 "Fort Pierre" and "Fox Hills" proper. A cross-section west of 

 Gallinas Mountains is given, showing "lignite" below "Fox 

 Hills."

Observations from David Baldwin's notes are quoted, supple- 

 menting previous observations by the writer and others. The 

 Laramie is said to overlie the Fox Hills, to be 2.000 feet thick 

 at Animas City, New Mexico, and to contain characteristic 

 Dinosaurs. The Puerco overlies the Laramie with apparent 

 conformity, but is faunally distinct. It is sometimes included 

 with the Laramie in post-Cretaceous series."
