Obs. A small depressed variety of this species has been found at two localities by Mr. Henderson. When the specimens are collected, the slightest touch usually destroys the whole of the shelly matter.
Loc. and Horizon. In a hardened shale, associated with Lamellibranchs, quarry on the north side of the Colinton road, under Craig-lockhart Hill, near Edinburgh; in shale with other marine fossils at Woodhall, as before.
Genus Lingula, Bruguière.
Lingula squamiformis, J. Phillips. Pl. I. fig. 7 (and fig. 8?).
Lingula squamiformis, J. Phill. Geol. Yorkshire, 1836, ii. p. 221, t. 9. f. 14; Davidson, Mon. Brit. Carb. Brach., Pal. Soc. p. 205, t. 49. f. 1–10.
Obs. This species was first recorded from the Cement-stone group by Mr. T. Davidson[1], and afterwards by the late Mr. Salter[2]. They give Wardie, on the shore of the Firth of Forth, between Leith and Granton, as the locality. In addition to one of the following localities, Mr. James Bennie has obtained L. squamiformis at two other localities in the neighbourhood of Mid Calder.
Loc. and Horizon. In hardened shale at quarry under Craiglockhart Hill (?), associated with Lingula mytiloides; in black shale in the Water of Leith at Dean Bridge, Edinburgh, Wardie-Shale division of the Cement-stone group.

Obs. Previous to seeing the specimens in Mr. Henderson's Cabinet, I had examined a few obtained by Mr. Bennie, on behalf of the Geological Survey, at Craigleith Quarry, and had submitted
