). 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 stem is very short (2.1 % CL) and the capitulum is long (22.4 % CL) and bare of any armature. As in the male, the total length of the frontal organ greatly exceeds that of the first antenna.

C). The length of the limb is 13.9 % CL. The curved, finely spinose, terminal seta on the dorsal side of the second segment is 4.0 % CL. The e-seta, which is flanged distally, is 58.3 % CL and the remaining a–d setae are 27.5 % CL.

D). Neither of the two specimens dissected had undamaged second antennae. The length is probably similar to the first exopodite segments (28.5 % CL). As in the male, this segment is slightly angled at a quarter length where muscles flexing the terminal segments are inserted. The combined length of the terminal segments is 9.5 % CL. The longest swimming seta is about 64 % CL, and the shortest terminal seta on the exopodite is 4.2 % CL. The first segment of the endopodite is roughly oval with its longest axis being 7.2 % CL (

D). The a- and b- setae are bare and curved, and 4.5 and 3.8 % CL respectively. The second endopodite segment is quite short (3.0 % CL). The long setae on the endopodite are bare; f-seta 49.8 % CL, g-seta 71.2 % CL, and the h–j setae are subequal, 30.0 % CL.

C). In one of the females dissected the caudal furca was intact. There are eight pairs of spines all of which carry fine secondary spines. The decrease in the lengths of the spines along the furca is small except of the final pair. The length of the longest caudal furca spine is 14.9 % CL.
