dimensions those of the Blanco species, rather than those of the Loup 
iFork; but the species could not be identified. 
“On the succeeding day, we drove, thanks to Mr. K. T. Cole, of Mobeetie, 
to the town of iMobeetie, in Wheeler county, eighteen miles S. E. of Miami. 
The route takes the traveler across a part of the Staked Plains, and a 
considerable distance before Mobeetie is reached, ravines belonging to the 
drainage system of the tributaries of the 'Bed Biver are passed. We exam- 
ined a number of these for a considerable distance without obtaining fos- 
sils. As we passed fhe deserted Fort Elliott, near to Mobeetie, I examined 
some sandy beds like thpse of the Upper Blanco beds, and obtained addi- 
tional tooth fragments of Equus cumminsii and a second species of Equus, 
(probably E. eurystylus, and fragments of teeth and other bones of unde- 
terminable camels. We thus determined the extension of the Blanco bed 
las far east as Mobeetie. 
“The result of my observations on this, the northeastern border of the 
(Staked Plains, is to the effect that this plateau to the north of the Bed 
Biver, like that part to the south of it, belongs to the Blanco deposit, 
giving the latter a north and south extent of two hundred and fifty miles. 
It had been hitherto positively determined at the typical locality only, 
that distance south of Miami, on the upper waters of the Brazos. From 
this point to the Bed IBiver the formation appears to be continuous, and 
the portion north of the Bed Biver now described not only has a close 
physical resemblance to the portion south of it, but contains, as now 
appears, fossils of the same age. (See Beport of the Geological Survey of 
Texas for 189^, for reports by Cummins and Cope on the Blanco Terrane.)”
