grap'h on :tibe Tertiary mollnsca of the State, with the intention of publish- 
ing it in the 5th Annual Report of that Survey. For want of funds 
the printing of this report has been indefinitely postponed, and accord- 
ingly the following facts and descriptions of new species, taken from the 
monograph in question, have here found an appropriate place for publica- 
tion. 
“The points in 'stratigraphy brought out by the study of the various 
Tertiary faunas of the State have been included with other matter in an 
article published by the State Geologist in the Journal of Geology, 1894, 
p. 549. (See Dumble, E. T.) 
“Suffice it to say here that the Midway stage, so well developed in Georgia 
and Alabama, and known also in Mississippi and Arkansas, exists also in 
Texas, as is proved by the occurrence of such species as Enclimatoceras 
ulrichi, Ostrea pulaskensis, Cucullwa macrodonta, Volutilithes limopsis and 
others. 
“The Lignitic stage, so far as has been observed, is destitute of molluscan 
remains. IThe exposure on IBrazos river, known as ‘(Smiley’s Bluff,’ two 
miles above the mouth of Pond creek, is evidently about synehronous with 
the Matthews 'Landing beds of Alabama. These are now included in the 
Midwiay stage. 
“The Lower Claiborne beds are replete with fossils, many of which are 
common to this horizon in Louisiana, Mississippi, Alabama, and South 
Carolina. Besides these well-known forms there are many new ones, some 
of which are described below. 
“The true Claiborne, the Jackson, and the Vicksburg stages seem to 
have no ^representatives in Texas. This fact cannot be too strongly em- 
phasized since most writers on Texas geology have referred certain fossil 
bearing outcrops to some 'of these upper Eocene stages.” 
Of the Pelecypoda sixteen new species and one variety are described; of 
the Gastropoda, fifty-four new species and eleven varieties, with locality 
notes.
