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 3.48 X 2.52 mm, with an 

 aperture of 1.14 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 maxillae. 



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 0.33 X 0.20 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. I have added this to the diagnosis.
