208 C. A. White—Molluscan Fauna of the Laramie Group. 
fossils were ever collected from any strata of the Laramie 
roup, I cannot admit. I regard all such statements as the 
result of a misunderstanding of the stratigraphical geology of 
ogi in which such observations are said to have been 
made. 
The true molluscan fauna of the Laramie Group has been 
published mainly by the late Mr. F. B. Meek and myself. 
Most of Mr, Meek’s species are figured in vol. ix. of the U.S. 
Geological Survey of the Territories; where they are referred 
now passing through the press, contains illustrations of all the 
known molluscan species of the Laramie Group. 
In former publications I have referred to the fact that the 
strata of this group have been recognized from northern New 
Mexico to the British Possessions; and from the meridian of 
Great. Salt Lake to that of Western Kansas and Nebraska. 
Besides the results of a full season’s personal work upon the 
Laramie Group in Montana, I have, within the past yeal, 
received collections of its characteristic molluscan fossils from 
roup. 
The collection that has been received from Mexico was 
made at a point about seven and a half miles northwest of 
Lampazos in the State of Nuevo Leon, and numbers seve? 
species, of which the following is a list:

illustrations, was published in 1880,
