WHITE.] LARAMIE FOSSILS. 55 
LIST OF FOSSILS FROM THE COAL-BEARING BEDS NEAR EVANS- 
TON, WYO. 
Pisidium saginatum White. 
tBulinus disjunctus White? 
*B. subelongatus Meek & Hayden. 
*B. longiusculus M. & H. 
Helix evanstonensis White. 
Macrocyclis spatiosa M. & H. 
*Columna teres M. & H. 
Hydrobia recta White. 
Those marked with an asterisk were originally discovered in unques- 
tioned Laramie strata. It will be seen that they are all Pulmonate 
Gasteropods, the significance of which fact I have pointed out in my 
former writings concerning the Laramie Group. 
Among the collections brought from Southern Utah by Professor Powell 
are the following, which evidently belong to the Laramie Group, and 
they are believed to have been all collected from strata which overlie 
unconformably those strata in that region which are properly referable 
to the Bear River Laramie series. Only the first and second forms of 
this list are illustrated in this article. 
LIST OF FOSSILS FROM UPPER KANAB, UTAH. 
tUnio gonionotus White. 
*Corbula undifera Meek, var. subundifera White. 
Planorbis (Bathyomphatus) kanabensis White. 
Physa kanabensis White. 
Helix kanabensis White. 
The collections of Professor Powell from the same neighborhood con- 
tained also some fossils that evidently came from strata referable to the 
Bear River series, and doubtless belonging beneath those which contain 
the fossils of the foregoing list. Among them Goniobasis cleburnt 
and Pyrgulifera humerosa were recognized. 
The collections brought in by one of the parties under the direction 
of Lieutenant Wheeler contain the following fossils, which are described 
and figured in Expl. & Sur. West of the 100th Merid., vol. iv, parti, hav- 
ing been obtained from the coal-bearing beds at Wales, Utah. ‘This col- 
lection is especially interesting, although so small, because it contains 
two species which are characteristic of the typical portion of the Laramie 
Group in Montana and Colorado. 
LIST OF FOSSILS FROM THE COAL-BEARING STRATA AT WALES, UTAH. 
Unio mendax White. 
Goniobasis nebrascensis Meek & Hayden. 
G. tenuicarinata M. & H. 
Viviparus ———? 
U. mendax was referred by me to U. vetustus Meek, in vol. iv, Expl. & 
Sur. West of the 100th Merid., but, afterward regarding it as a distinct 
species, I gave it the name U. mendax, in Bull. U.S. Geol. Sur. Terr., 
vol. iii, p. 605. This species, together with Goniobasis nebrascensis, 
and a Viviparus closely related to, if not identical with, V. trochiformis 
M. & H., were also recognized among the fossils of a collection brought 
tThese two species are illustrated in this article; the former on plate 20, and the latter 
on plate 28.
