Vaitghan.] RECONNAISSANCE FROM ('LINK TO EAGLE PASS. L )( ,) 
There is an oyster, probably 0. cortex, besides which Mr. Stanton 
has identified the following fossils from the collection made at this 
place: 
Limopsis? sp. 
Gyrodes petrosa Morton. 
Strepsidura ripleyana Conrad. 
Pyropsis sp. 
These indicate, according to Stanton, the fauna of the Ripley and 
Navarro beds. 
For about a mile after passing Salado ('reck the surface is composed 
of residual sands, with occasional outcrops of yellowish sandstones. 
For the next half mile there are sands with some gravel embedded in 
them. For the next 5 miles the soil is usually argillaceous, or a mix- 
ture of sand and clay, and there is a considerable amount of gravel 
scattered over the surface. In ascending a small hill 5£ miles 
beyond the Salado crossing many fossils were found in a hard layer 
of greenish sands, which overlies soft yellowish and ^greenish sands 
and clays. Mr. Stanton identified the following species from a col- 
lection made at this locality: 
Trigonia sp., a small imperfect specimen related to T. eufalensis Gabb. 
( lardium sp., a form that is abundant in the Navarro beds at Corsicana, Texas. 
Veleda lintea Con.? This also occurs at Corsicana. 
Turritella trilira Con. variety. 
Baculites ? sp., a crushed fragment. 
Mr. Stanton remarks: "The fossils from this locality and those 
from Hi miles north of Eagle Pass, near Burr's ranch, and 2 miles 
north of Eagle Pass are nearly all either identical with or closely 
related to species that occur in the Ripley fauna of Mississippi and 
Alabama and in the uppermost Cretaceous beds of Navarro and Kauf- 
man counties, Texas. This fauna has a vertical range of several hun- 
dred feet in Alabama." 
Six and a half miles below the Salado crossing the foundation of the 
soil is a yellowish-brown clay. Gravel is scattered over the surface. 
It is chiefly flint, but there is also a considerable admixture of por- 
phyry, showing that the gravel lias been brought down by the Rio 
Grande. 
Although there is not a continuous coating of gravel over the hills 
from this point (17 miles from the Eagle Pass court-house) to 
Eagle Pass, gravel occurs, in more or less disconnected patches, the 
whole distance. The rocks consist of alternations of yellowish flaggy 
sandstones and clays. From about 114 to 11 miles north of Eagle 
Pass Exogyra costata was found in considerable abundance in yel- 
lowish clays. These clays are both overlain and underlain by soft 
yello v sandstone. This clay bed, by aneroid barometer measure- 
ment, is 50 feet thick. The road runs approximately along tin 1 strike
