TWENTY-NINTH ANNUAL MEETING. 93 
- Canis, species indet.: A complete mandible of a small species of dog was ob- 
tained in the elephant deposits in Lane county, by Mr. Martin. I do not, at 
present, have access to the specimen and cannot give the specific name. 
Canis Lupus: A complete skull and other parts of the skeleton are in the 
. University collection, obtained from near Goodland, in apparently the same de- 
posits which yielded the Platygonus remains. 
Mercatonyx tempyi1: An excellent skull of this species, the type specimen, 
was obtained a few years ago from the Equus beds, near McPherson, associated 
with Hquus major,a species found associated in the east with Megalonyzx. 
Cragin has reported the same species from Clark county, associated with other 
species of Equus. JM. leidyi was described by Lindahl. 
Mytopon (?) species indet.: A fibula was doubtfully referred to Mylodon 
by myself in a paper in the Kansas University Quarterly. The bone came from 
30 feet below the surface, at Seneca, Kan. 
GEomys BURSARIUS: A number of skulls of this species were found associat-d 
with remains of the Alces described above, 50 feet below the surface in the 
“*Joess’’ near Kansas City. The skulls cannot be freed from the very hard 
matrix, but such portions as are exposed agree perfectly with the living species. 
Bones of the living Spermophilus tridecemlineatus were found associated 
with the bones of Platygonus at Goodland, but I suspect that they were from 
old burrows. 
Cragin has reported Felides from the Meade gravels, and Cope has described 
a saber-toothed cat (Dinobastis ) from Oklahoma. 
Usually the Pleistocene, or Quaternary deposits in eastern Kansas do not 
exceed 60 or 70 feet in thickness, though 150 is the thickness given for them at 
Kansas City by Mudge. At Lawrence, borings in the river valley gave about 60 
feet as the thickness, or about 40 feet below the present river bed. Of course it 
is possible that borings elsewhere in the river valley migbt give greater depths. 
The material at these depths was coarse gravel, partly of glacial origin. Varia- 
tions in the coarseness of the gravel and sand were found at different depths, but 
no fine, sandy mar! was found save at or near the surface. i 
The Equus beds evidently form the whole of the superficial deposits of west- 
ern Kansas. They are, toward the surface at any rate, composed of light-colored 
calcareous marl, the Plains marl of Hay, with sufficient clay to make fair bricks, 
which burn a light red. Its depth it is impossible to say, but I suspect that it is 
considerable. If Cragin is right in ascribing 200 feet and over as its thickness, 
then in all probability there area hundred feet or more on the upland plains. In 
the river valleys, the material scarcely differs, save often for the greater propor- 
tion of calcareous material derived from the Cretaceous beds below them. 
How these upland deposits were formed is not clear to me. That there could 
have been extensive lakes over these plains during Champlain times is impossi- 
ble, since cotemporary deposits of local origin are found in the valleys, containing 
vertebrate fossils of the Champlain epoch, and lakes on the uplands must have 
been banked up to have existed. That they are river deposits is equally inde- 
fensible. Taking into consideration the uniform fineness of the material, the bar- 
renness of the fossils, and their poor petrifaction, and the absence of coarser 
pebbles, everything seems to show an eolian origin. . 
Hatcher found evidence of unconformability between the Loup Fork and 
Equus beds in western Nebraska, and stated that Marsh had confounded them 
and confounded the fossils which he had described from them, which seems not
