Hyaline R. Frost's RR. Top of Benycton li. J. at Commel Shoal Creek del Rio lve. Saturday Feb 13, 1926 Took the billy to Shoal Creek North Austin; and then walked for half an hour to the locality in the top of the Benycton. This dell side locality faces the rifle-range. Got none of the same things gotten on Jan. 30. There are two kinds of echinids here. The common one is H. elephant; during some of these are wrapped with spines and serpulae, but half they did not remain buried after death in the mud, but others worked at by the waves. Got one by spines. Collected by myself at Shoal Creek on Feb 15, Got 2 other Enallasterus and many fine E. asietina and Borispocaeas. Also a good slab of E. leu zygoma
