(Pp. 72-76) The author describes the coal beds of the Cer- 

 rillos field, and mentions those of the Rio Puerco and other 

 New Mexico fields.

The Cretaceous is not subdivided in this report. Several of 

 the fossils described are from the Rio Puerco and neighboring 

 regions.

(P. 314) The fossil plants from Placiere (Cerrillos field) are 

 included in the Tertiary flora. They are Palmocarpon compo- 

 situni Lx. ; Carpites ligatus Lx. ; Pahnocarpon mexicanuiii Lx. ; 

 Carpites spiralis Lx. 



The formation (the Mesaverde of the Cerrillos field) is 

 placed in the "first group," together with those in the Raton, 

 Canyon City, Denver, and other coal fields.

(P. SO) Puerco (?) is shown as occurring above Laramie. 



(P. 52) The Puerco marls first observed by Cope in 1874 were 

 referred by Endlich in 1875 "to the lowest place in the Tertiary 

 series, but the absence of fossils renders it difiicult to conclude 

 whether they belong here or in the Laramie series."

(P. 471) The coal beds north of Placer Mountain (Cerrillos 

 field) are referred to the Laramie, and the underlying shale ex- 

 posed near the town of Galisteo to the Pierre, Niobrara, and 

 Benton. 



The Galisteo sandstone is described as lying unconformably 

 on beds ranging from "Laramie" to Dakota. (This probably is 

 not the Galisteo of other writers.)
