Grypheea Pitcheri — Marcou . 
191 
Dr. J. S. Newberry, geologist to the Colorado exploring expe¬ 
dition, under command of Lieut. J. C. Ives, 1857-58, gave in his 
“Geological Report,” Washington, 1861, at p. 85, the Grypheea 
pitcheri , as found by him in his section of the cliffs called “mesa 
wall, Moquis village;” in his No. 12 of the group of strata and 
in the succeeding number 18, he mentions another variety of 
that species under the name Grypheea pitcheri var. navia. At 
p. 94, Dr. Newberry gives the Grypheea pitcheri not the variety, 
as found by him near Fort Defiance, in the “Canonita Bonita.” 
At p. 97, at Cov^ro, he says: “The greenish shales, enclosed in 
the yellow sandstones, contain a large number of Grypheea 
pitcheri ” and finally, at p. 154, he mentions the Grypheea pitcheri 
var. navia found by him on the banks of Pecos river. 
In the chapter XI, Paleontology p. 120, Dr. Newberry refers 
to Morton’s synopsis for the Grypheea , found by him a few 
miles east of Fort Defiance, near Covero, banks of the Pecos east 
of Albuquerque; and he adds: “This is the typical form of the 
species as given by Morton.” Farther on, he refers the Grypheea 
found by him at the Moqui villages, east of Fort Defiance and 
on the Pecos, to the Grypheea pitcheri var. navia Hall, Pacific 
R. R. Repts., vol. hi ; Geol. Rept. p. 500. PI. i, figs. 7-10. “This 
shell should perhaps be considered specifically distinct from the 
preceding (G. pitcheri) * * * these shells should be 
carefully scrutinized when used as palaeontological evidence, 
and deductions made from them should be given their proper 
subordinate value ;” thus depreciating as much as he could the 
value of the genus Grypheea ; but taking care not to give a 
single figure or a single word of description of what he calls 
Grypheea pitcheri and Grypheea pitcheri var. navia . 
Sixteen years later, in 1876, Dr. Newberry published his “Re¬ 
port on the exploring expedition from Santa Fe to junction of 
Grand and Green rivers in 1859” under the command of Capt. 
J. N. Macomb. At p. 33, he mentions twice the Grypheea 
pitcheri, as found by him in the valley of the Red fork of the 
Canadian river. He repeats at p. 52 that he found the Grypheea 
pitcheri near Galisteo at Capt. Pope’s artesian well. At p. 104 
he indicates in his section of the valley of the Rito del Sierra 
Abajo, of the San Juan river, the Grpyhcea pitcheri as the only 
fossil found there. Dr. Newberry, farther on at p. 115, de¬ 
clares that in the Naciniento mountains he found the Grypheea
