). My preliminary examination showed that in all probability they are specimens of Müller’s species. They agree with all the limited information given in Müller’s original description apart from one detail—they lack any carapace sculpture that gave rise to the specific name. However, in many species of halocyprid the expression of striations on the surface of the carapace can be very variable, so there seems no reason at this stage to describe these specimens as a novel species. The specimens were not particularly well preserved, probably because all the specimens would have died while the nets were being retrieved as they passed through the extensive oxygen minimum zone that at the time lay between

The overall shape is also in good agreement. The rostrum is short (9.7 % CL) and the incisure is very shallow (6.2 % CL). On the lower anterior margin of the incisure is a translucent flange that is a typical feature of the genus, but is somewhat smaller in this species. The opening of the asymmetrical gland on the left carapace valve is level with the posterior end of the carapace hinge, and the one on the right valve is at the posterior ventral corner.

species. The limb is five-segmented and is sharply angled ventrally at the suture between the second and third segments. Its length, not allowing for the angle, is 14.9 % CL. Dorsally at the distal end of the second segment is a short (3.8 % CL) spinose seta that arches anteriorly. Both the first and the second segments have extensive patches of quite coarse bristles. On the first segment there is a patch on the dorsal surface of the segment. On the second segment there is a patch around the base of the dorsal seta and another on the outer flank. The penultimate segment carries two long setae and the terminal segment three. The longest of the terminal setae, the e-seta is 64.9 % CL and is bare. The other four setae are subequal and 35.1 % CL long.

E). The shape of the limb matches the usual halocyprid form. The first endopodite segment has a bare dorsal seta that barely extends beyond the end of the second segment. There are four ventral setae, one of which is long and inserted on the outer face. The second segment has the usual three terminal dorsal setae, one long and two shorter, and two quite long ventral setae. The terminal segment carries the usual seven setae, of which two are long and claw-like. The longest seta was broken on both sides in all five (male and female) specimens dissected, but is at least half the length of the endopodite.

There are two pairs of lateral setae on the basale and a subterminal seta inserted near the articulation with the endopodite. Around the base of the subterminal seta are patches of quite coarse spines. The exopodite is represented by a single, stout, densely plumose seta.</paragraph>

C). The fifth limb has an epipodial formula of 4 + 5 + 4. The basale has ventrally a basal group of four setae and a distal pair, laterally two pairs and a single plumose seta on the outer surface, and a long dorsal seta. The first endopodite segment has a single medial seta dorsally and a pair of medial setae ventrally. The terminal segment carries the usual three setae; the dorsal one being the longest (10.5 % CL).

D). The epipodial formula is 6 + 5 + 5. Two setae are on the coxale; the basale has five setae ventrally, one laterally and a dorsal seta. All these setae, with the exception of the dorsal seta, are plumose. The first endopodite segment carries only a ventral seta at two thirds length. The second segment had a medial seta both ventrally and dorsally. The third segment carries the usual three setae, of which the central one is the longest (13.6 % CL).
