Description

Tectura (Pilidium) COPPINGERI, sp. n. (Plate IV. figs. 12, 12a.)

 

Shell cap-shaped, thin, sculptured with numerous fine, thread-like, granulous liræ radiating from the apex to the margin, and with fine concentric lines of growth. The colour is dirty white, varied with two or three bands of a pale slate-colour which encircle the shell at irregular intervals, and are interrupted by the radiating liræ, which are white. This feature is more apparent within the shell, where the surface is very smooth and shining. Margin nearly simple, very faintly crenulated by the extremities of the ridges, roundly ovate in form. Apex rather acute, not greatly curved down, and very near the anterior end. Length 5 ⅓ millims., diam. 4⅓, height 2½.

 

Hab. Station 7.

 

This is the southern representative of the northern Tectura (Pilidium) fulva of Müller. It is rather more circular than the latter; and the colour of the single specimen at hand is different.”
