Hveryoiie who is familiar with assimilation of strata and par- 
allelism of formations, always lakes special care to give proofs of 
identity of fossils. l)y means of good figures and descriptions of 
species. Here not a single fossil pretended to be identical with 
fossils of the Washita division, is either figured or descri})ed. 
]Mr. (/ummins contents himself in saying: '-I Ijelieve if Marcou 
had seen tin' fossils 1 have collected he would not have hesitated 
to plact' the Tucumcari beds in the Cretaceous." T shall 
ask simply, why Mr. Cummins did not send me his fossils to 
look at? 
Till' Ammonites, which are always among the most important 
fossils for determination of age of the strata, are not even hinted 
at: simply saying Aiiniiniiltis. 
Professor A. Hyatt made an extended and very minute explor- 
ation of the Tucumcari area in 18811. He collected numerous 
and important series of a (^uantit}' of fossils — at least sixty spe- 
cies — and he asked me to look over his collection with him. I 
did not see in it a single Cretaceous fossil; no Gri/plia'a pitcher!^ 
no h\nH/i/ni tijiiun. etc. Professor Hyatt is justly considered as 
the best specialist, on this side of the Atlantic, for fossil ceph- 
alopods: and he has already worked out for the Greological Sur- 
vey of Texas, the •Carboniferous cej)halopods"' published in the 
tS'-roiii/ Jim. Hip., and is now engaged on the Nautilidaeof Texas.
