164 Mesozoic Series of New Mexico. — Marcou. 
HI. — Table showing the order of succession and classification of the 
Mesozoic series of New Mexico, by J. S. Newberry, 1858. 
Upper Cretaceous of the white mesa, Moqui country.

Cretaceous. J No. 1. In it at Moqui village. Dr. 
SYSTEM. 1 Newberry says that he found the 
Gryphiea pitcheri of the Neocomian 
of Comet creek and fort "Washita 
t (Indian territory). 
Dr. Newberry declares that there is no Jurassic system on the route 
followed by Mr. Marcou from Zuni to Pecos village. But at the 
Moqui Pueblo — not visited by Marcou — he found a lignite or coal bed, 
which he is inclined to consider either as Jurassic ( ?) or Upper 
Trias. (?) In his sections and on the geological map, that lignite bed 
is included in his division of "Variegated marls." 
Trias (Variegated marls of the Moqui country, comprising the

The geological report of Dr. Newberry is published in the vol- 
ume of the "Colorado exploring expedition," Lieut. J. C.Ives, 
4to, Washington, 1861, It contains three plates of fossils and 
two geological maps. In the geological map No. 2, Dr. New- 
berry not only suppresses the Dyas (Permian), which he ad- 
mits in a certain degree in his report, but he also colors as 
Carboniferous a large area of Trias, from Big Dry Fork to Cas- 
cade. He colors the Trias on only half the area it really oc- 
cupies there, and as I colored it on my geological map of 
New Mexico of 1853, and on my general geological map of 
the United States of the same date, and finally Dr. Newberry 
colors on his map No. 2 as Cretaceous, not only the Creta- 
ceous beds there, but also all the Jurassic system and all 
the Keuper of the Triassic system, which covers large areas 
between Moqui and Zuni. 
Dr. Newberry has "failed to recognize the Jurassic forma- 
tion in any of the localities where it has been said to occur"by 
Mr. Marcou,referring it to the Cretaceous of the upper Missouri 
valley or marly chalk (Turonian) "the Triassic formation of 
Mr. Marcou" is so much reduced, that its thickness is only
