Extract

The specimen here figured is an internal cast of a right valve, occurring in the well-known, reddish, fossiliferous, Palæozoic quartzite of the Triassic pebble-bed at Budleigh-Salterton, in Devonshire; and it resembles some forms of Cypridina brevimentum, J. and K. (“ Monogr. Carbonif. Entom.” Pal. Soc. 1874, p. 15, pl. 5, figs. 15–19), in general aspect; and also in some respects Polycope simplex, J. and K. (op. cit. p. 54, pl. 2, fig. 12). It was detected by the late Mr. J. W. Salter (in 1865?) during his enthusiastic study of that interesting conglomerate.

Leperditia ? Cambremis, Hicks. “Red shales of the Longmynd” group. This seems to me to be quite indeterminable at present. See Q.J.G.S. xxvii. p. 396, and xxviii p. 184.
