fringe, and of the upper rib or dorsal crest. One fragmentary specimen from 
Carland bears the remnants of two lobes and a dorsal crest. Probably, when 
complete, the valve may have been very much like that of Beyrichiopsis jfimbriata, 
fig. 10, pl. xi, Geol. Mag., 1886. The fringe and ridges may be damaged, 
undeveloped, or obsolete. There are some fringeless forms, probably belonging 
to this group, in the Cultra Shales; and a fringed specimen, without ridges (from 
Cultra) is figured in the Geol. Mag., 1885, pl. xit., fig. 5. 
Beyrichiopsis fimbriata belongs to the Lower Carboniferous series of Northumber- 
land, Roxburghshire, Linlithgowshire, and Fifeshire.

Judging from their size, it is not unlikely that the larger specimens from 
Carland belong to Beyrichiopsis fortis, although they have not preserved the 
longitudinal riblets. 
B. fortis is found in the Calciferous Sandstone of Roxburghshire.

Sub-oblong, with rounded, almost equal ends; straight hinge-line, and gently 
convex or slightly sinuous ventral border; surface marked with a medio-dorsal 
sulcus, of variable proportions, narrow or broad, between two tubercles or lobules, 
also of variable dimensions. A more or less distinct, narrow ridge, straight or 
slightly curved, passes along the ventral region below the two bosses, scarcely 
connecting them. In figs. 11 and 14 this becomes a broad ventral band; see p. 199.
