145 August 13-1918. Table Head section revised. Laga nautili, Rafinercus picator, Dawsonreus prionus. Onesocus sp., small estomies of mania byptra. Only a few poorly preserved gastropods were seen, as Maduritis communis but the M. of the Chazy are very rare in strata. Rafinercus attains large size, up 2'9" long with the epyp m- complete and a dia. width of 1 1/4 inches; body chamber 9" long and 5 1/2 inches in diameter at the largest end. The last septa are 7's inch apart. In the afternoon drilling down in the section fossils are scarce beneath the sponge bed for 130 feet. At this level Lepuditra are common along with mud bryozoan and trilobites, Pleioneus icarus, Commin Rafinsquonia aurora. Obscure gast. are also seen. At 150 down Lepuditra, pug of trilobites, Hormitoma sorcula and Rafinercus sp. Fossils are scarce then to 190' down. Here occur Tornicofelis acuminata (its highest occurrence) and laga nautili, fragments of tril. Hormitoma simulatrix, Rafinercus A. Dawsonreus prionus. At 200' down common in T. acuminata. Associated with it is a small operculum the right size and shape to first. This is the only gast. seen here and the operculum doubtless belongs to it. At 260 feet down there is another gray slate with Lepu- ditra, T.acuminata, Rafinercus and frag. of tril.
