Protomedeia prudens J. L. Barnard

Protomedeia (?) prudens J. L. Barnard, 1966a, p. 83, fig. 36.

MATERIAL.—Stations 73 (4), 75 (1), 1001 (1).

Protomedeia prudens and P. penates J. L. Barnard (1966b) are very similar, the former occurring in deep waters off western America and the latter in shallow water of Tomales Bay, California. Protomedeia penates has a thickened article 4 of pereopods 1–2, an obliquely rounded posteroventral corner of pleonal epimeron 2, larger coxae and stouter and shorter fifth articles of gnathopods 1–2 than does P. prudens. The material at hand especially fits the description of P. prudens in its slightly protruding epimeron 2 and the narrow article 4 of pereopods 1–2. Parts previously unknown for P. prudens are illustrated here: especially pereopods 3–5 and the female gnathopods.

DISTRIBUTION.—Oregon to southern California, 121–400 m.
