are only a mile or two away, and is cut across by a lateral stream at this place, and shows to have been several hundred feet wide on the north side of the creek.

The shells from the above locality do not vary from those previously submitted from Tule Canyon, Fork of Groesbeck, etc., and the material in which they are imbedded, i. e., a coarse quartz sand, appears to be identical with that from the other localities. There was, however, in this sand a specimen closely resembling some fragments of marine shells found in the Orange sands of Washington county, but too badly waterworn to refer it to any genus, or even to state positively that it was a shell fragment.

The material is of interest, as it gives us another locality for Vallonia gracilicosta, Reinh., and Patula striatella, Anth., two species that have, so far, been found only as Pleistocene. fossils within the boundaries of the State.

LIST OF PLEISTOCENE AND RECENT SHELLS.

The following is a list of the shells as determined by Mr. J. A. Singley, and his remarks on the same:

I hand you herewith a list of the shells submitted to me for determination. The list is of interest as giving a number of species not heretofore recorded from the State, and although most of the species new to Texas may prove to be subfossils, there is a probability that some of them may be living in the vicinity of where these dead shells were collected. Except where noted the shells were dead and bleached.

List of Shells.
