Science. 78 UNITED STATES NATIONAL MUSEUM BULLETIN 296 Retractor corporis and retractor orijicii muscles are present, retractor pallii rostralis muscles are absent. A single pair of ventral body processes are found on the thorax. The size of the female figure, calculated from the stated magnification, is X mm, with an aperture of mm. The mouth cirri are biramous on a two-segmented protopod. The rami have five and four, or seven and five segments. Three pairs of biramous, multisegmented terminal cirri bear typical setation. A pair of short, two-segmented caudal appendages bear three terminal setae. The mouthparts are the typical mandible with palp and two pairs of Figure 16.—Kochlorinopsis discoporellae Stubbings, 1967, female, side view: a, showing mantle musculature, ovary, and egg mass; b, with mantle removed, setae omitted from the terminal cirri (after Stubbings, 1967). The male is triangular, with a single, remarkable, two-jointed antenna. The posterior is blunted, and a penis is apparently present. It measures X mm. I have not examined a specimen of this species, but rely on Stub- bings' description, to which the reader is referred for more details. Stubbings did not distinguish in his diagnosis of the genus Koch- lorinopsis a point which he makes in his description: the lack of a retractor pallii rostralis muscle.
