Nota: For Farran: the distinguishing characters are beyond the size (1.05-1.1 mm), the wide spreadind 3rd thoracic segments, the blunt tips to the 4th thoracic segments, the fine setae in front of the genital openings, the anal segment as long as it is broad at the base and nearly as long as the caudal rami, and the single seta on the endopodite of P4.

Espèce Corycaeus (Onychocorycaeus) ovalis - Planche 11 de figures morphologiquesIssued from : G.S. Brady in Ann. Durban Mus., 1914, Vol. I. [Pl. I, figs. 6-9]. As Corycaeus latissimus ?
Female (from Durban Bay, Natal): 1, habitus (dorsal); 2, same (lateral); 3, A2; 4, Md; 5, outer branch of P2; 6, terminal spine, outer branch of P2; 7, terminal spine, inner btanch of P2: 8, inner branch of P3; 9, terminal segment of inner branch of P3; 10, P5.

Nota female:
- Anterior division of the bpdy ovate, greatest width in front of the middle and equal yo more than half its length, broadly rounded in front, narrow and constricted behind, the 3rd segment produced laterally into very conspicuous wings, which are broad at the base and projected backwards, ending in long acuminate points.
- Urosome 2-segmented, 1st segment nearly twice as long as the following one and excessively tumid.
- Caudal rami equal in length to the last abdominal segment; 3 terminal setae, short.
- eyes remote.
- Apical spines of exopodites of P1 and P2 long and slender, outer edge very feebly pectinated; terminal spine of endopodite small, lancet-shaped and pectinated.
- Endopod of P3 destitute of spines, the last segment ovate, its apex obliquely rounded off; its inner margin bearing 2 setae.
- Endopodite of P4 consisting of a small papilla with 2 long setae.
- P5 reduced to a single short seta on each side of the last thoracic segment.

Remarks: The two species which most nearly approach this in general character are C. latus Dana, and C. obtusatus (= spp.) Giesbrecht, but neither of these appears to be at all so robust or tumid as the present species. Specimens referred, with some hesitation, to the latter of these two species were founded abundantly in Durban Bay, but are easily distinguished by their smaller size and by their beautifully opalescent blue tint, which appears to be dependant upon masses of dark blue pigment scattered about the tissues of the animal.
