iThe conclusions respecting the age of the formations penetrated are 
hriefly as follows: 
“Depth in feet. Geological Horizon. 
4'6 to 458 Pleistocene. 
458 to 1,510 Doubtful. 
I,5d0 to 2,158 Upper Tertiary. 
2,158 to 2,920 ^ Miocene (Upper).”

“Texas, iStation 2440, — ^The occurrence of the Midway stage in Texas is 
confirmed by a few molluscan remains recently brought from Kaufman and 
Travis counties by Mr. T. W. Stanton. Four miles northeast of Kemp, 
in the former county, this horizon is represented by light gray and yellow- 
ish calcareous sandstone icontaining Cuciillcea mucrodonta ( in great abund- 
ance), Cytherea, Venericardia planicosta, Turritella mortoni, Natica ala- 
bamiensis. 
“Near Webberville, Travis county, on the Colorado river below Austin 
(iStation 2439) , Mr. Stanton found a elayey limestone more or less streaked 
with brown and yellowish ahades, but 'usually of a light yellowish -gray hue. 
Chocolate colored siliceous pebbles, generally cuboidal in form, are often 
found in the more elayey beds. The enclosed shells, nearly always crystal- 
line, are Cucullcea macrodonta, Leda, Venericardia, Venericardia planicosta, 
Crassatella (large) LUhodomus, Volutilithes? Coral, 'Shark’s teeth. 
“iStation 583 (18 miles southeast of Eagle Pass, Texas, first night’s 
oani'p, October 2i5, 1887. — ^C. A. White). The fossils collected here by Dr. 
White are Gucullcea macrodonta, Pectunculus, Venericardia, Cardium. 
“The shelly matter of these species is completely crystallized. 
“The matrix was evidently a calcareous light sand or sandstone. 
“'This place is far to the north of Laredo, where Claiborne fossils are 
found. Much doubt is felt regarding the Tertiary affinities of some of the 
fossils, although they were turned over to the writer from the Mesozoic 
idivision of the U. 'S. Geological 'Survey as non-Cretaceous forms.”
