Planche 1 issued from : J.R. Grindley in Ann. S. Afr. Mus., 1963, 46 (15). [p.376, Fig.1].
Female (from W & South coasts of South Africa): a-b, habitus (dorsal and lateral, respectively; c, A1; d, P5; e, distal part of P5 (enlarged); f, genital segment (ventral); g, anal segment and caudal ramus; h, genital segment (lateral); i, comb-like seta (enlarged); j, P4; k, P1.

Nota : Rostrum well developed with 2 strong filaments. A1 31-segmented, reaching the 2nd urosomal segment ; segments 1+2, 3+4, 8+9 and 24+25 apparently fused (Giesbrecht & Schmeil, 1898, and Marsh, 1933 reported 22 segments). A specialized comb-like set is present on the third last segment, it lies parallel to the antennula, its distal en dis curved and slightly expanded and bears about 3 distinct recurved hooks and a number of much smaller ones which grade into a series of minute comb-like teeth (3 micron long and 1 micron apart) along the shaft of the seta, there is a bulbous swelling near the base of this seta. ; there is also an unspecialized plumose seta on this segment.
Cephalosome and pedigerous segment 1 partly separate ; pedigerous segments 4 and 5 fused.
Posterior angles of metasome with a sharp spine on each side on the postero-dorsal margin.
P5 uniramous, 4-segmented and asymmetrical, particularly as regards the hyaline projections of the inner margin of the 2nd basal segment (there seems to be some individual variation in the forms of these projections ; Marsh, 1933, suggests that these might be regarded as rudimentary indications of an endopod ; such rudiments are present also in P. stuhlmanni). The outer distal angles of the 1st and 2nd basal segments are produced into very small spines ; the 1st segment of the ramus bears 1 spine near the distal end of the outer margin ; the 2nd segment bears 1 spine on the outer distal angle an dis produced distally on the medial side into a large curved spiniform process bearing short bristles on the anterior and posterior margins and reaching about the midpoint of the terminal spine ; the terminal spine has a small distinct basal portion bearing a slender plumose seta on its posterior face, while the long terminal blade-like portion is furnished with minute bristles on its anterior and posterior margins ; terminal spine, including the basal portion, slightly longer than the 3rd segment (marsh, 1933, points out that the distinct basal portion of the terminal spine found in some species is not a real segment but a modification of the terminal spine or ‘’hook’’).
Urosome 4-segmented and almost 2/3 as long as prosome.
Genital segment asymmetrical, with irregular swellings laterally and a prominent genital boss ventrally ; a number of setae present mainly on the lateral swellings, and there is a patch of fine hairs in the middle of the dorsal surface. The genital boss bears a row of spinules anteriorly and the genital flaps each have a distal seta. The egg sac is single, containing about 25 eggs.
The first three urosomal segments are furnished with rows of coarse teeth on their postero-dorsal margins.
Caudal rami divergent, more than 3 times as long as wide and with fine hairs on their inner margins ; the 3rd or middle caudal seta (not counting the sensory bristle between the 4th and 5th setae) is broad and flattened in a characteristic blade-like form, it is about 3 times as wide as the other setae.

Endopod apparently 4-segmented, 3rd segment small and indistinct, with setal formula 1, 2 +3, 1, 2 +3, respectively.
Md with gnathal blade heavily chitinized and bearing about 10 fine teeth and a plumose spinule. Basipod of palp with 4 inner marginal setae. Exopod indistinctly 3-segmented, bearing 1 lateral and 5 terminal setae. Endopod 2-segmented, bearing 4 setae on segment 1 (1 separate) and 8 setae distally on segment 2 (1 jointed and crooked), this last segment is narrowly triangula rand bears a row of tiny bristles.
Mx1 with 1st inner lobe bearing about 10 strong spines, 2nd inner lobe bearing ?3 setae and 3rd inner lobe bearing 3 terminal setae ; outer lobe bearing 8 long setae ; exopod with 9 marginal setae ; endopod 3-segmented bearing 4 setae medially on the basal portion andgroups of 4 setae medially on segments 1 and 2 and approximately 7 termi,nal setae on segment 3.
Mx2 with 5 large medial lobes (endites) and 2 smaller terminal lobes each bearing 3 or 4 setae. Distal portion indistinctly segmented.
Mxp 6-segmented, 2 basal segments large and 4 distal segments small and decreasing in size distally ; 1st segment with 3 medial lobes bearing 2, 3 and 2 setae +1 spine, respectively ; there are short fine hairs medially and tiny hooked spinules on the 3rd lobe. 2nd segment expanded medially with 3 setae and a fringe of short fine hairs on the medial margin. 3rd segment bearing 2 + 3 setae. 4th segment with 2 setae. 5th segment with 2 setae. 6th segment with 2 setae medially and 6 on an outer lobe. Among the setae on segments 3, 4 and 5 are four with a peculiar branched structure, these branced setae have a thickened basal portion and divide near their middle, one branch continuing as a thinner seta forming the extension of the proximal part while the other is short, broad and spatulate, fringed with short curved spinules (well noted by Mrazek, 1894).

In the left leg the 1st basal segment is naked and the 2nd basal segment bears a few spinules near the outer margin, some rugosity on the inner margin and a long hyaline endopodite ; this has an expansion basally, is apically acute, and bears a fringe of about 8 fine hairs near the apex.
