Cumacea: 26. Campylaspididae, 1. Oampylaspis 193 



distinguished from those of C. mbicunda {m. 7) by molar of mandible rather 

 longer and more slender, palp of maxilla 1 with 2 filaments, epipod of maxilli- 

 ped 1 with only 3 branchial sacs. Maxilliped 2 with 3^ joint distinct, terminal 

 joint carrying 3 spines. Maxilliped 3 with dentate margins, 4*1^ joint little 

 broader than 5^1', equal in length to 5^'' and 6^^ joints combined; its apical 

 setae very long. Peraeopod 2, 2^^ joint less than a third of the total length, 

 b^^ with a serrate margin, 7^^ as long as 5**1 and 6^^ combined. Peduncle 

 of uropods more than twice as long as the telsonic segment, indistinctly 

 serrate; exopod a little longer than the endopod, about half as long as the 

 peduncle, its long terminal spine serrate. L., subadult, 31 mm. 



(S. Imperfectly known. Pseiidorostrum more horizontal than in 9, 

 carapace less deep, the spines for the most part reduced to tubercles, but 

 those on pleon segments even longer than in Q . L. 3-7 mm. 



Mediterranean, near Capri; depth 950 — 1100 m.

Pseudorostral lobes meeting for a short space subacutely in front of 

 the narrowly oval eyelobe; antero-lateral corner obtuse, slightly produced 

 below a shallow sinus. Carapace much dilated, but not nearly half the 

 length of the body, dorsal line evenly vaulted behind, sides sculptured with 

 3 paii's of distinct oblique folds or subcrescentic carinae, the hindmost at the 

 middle bifurcating, so that a 4*^ fold nearly reaches the hind margin and 

 then turns forward to rejoin the S"^ in the submedian line. Pedigerous 

 segments 1, 2, slightly produced dorsally, each with median procurved or 

 erect point; 5*^ pedigerous and fii-st 4 pleon segments carry each a pair of 

 adjacent dorsal tubercles. Telsonic segment pentagonal, length and breadth 

 equal. Eye distinct, showing 4 lenses (in fig.). Maxilla 1, palp with 2 filaments. 

 Maxilliped 1, terminal joint less rudimentary than usual in the genus. Maxilli- 

 ped 2, terminal joint carrying 3 spines, the smallest intermediate. Maxilliped 3, 

 4*^ joint not greatly expanded, nor nearly as long as the next 2 joints combined. 

 Peraeopod 2, 1^^ joint, scarcely longer (G. 0. Sars in text) or rather shorter 

 (in fig.) than 2 preceding joints combined. Peduncle of uropods unarmed 

 in 9, with the usual setae in 6, not twice as long as the endopod, which 

 is a little longer than the exopod; the latter in the 9 is figured a little more, 

 in d a little less, than half the length of the peduncle. Colour pale reddish. 

 L. o 5 mm, d 6'o mm. 



Norway, Heligoland, British Islands; depths 38 — 274 m.

Integument thin and semitransparent (much less so in supposed d). 

 Pseudorostral lobes well produced in front of the short narrow eyeless eye- 

 lobe, apically acute, convex in dorsal outline, antero-laterally receding to a 

 shallow sinus and obtuse corner. Carapace more than half the length of 

 the body, with 2 pairs of finely serrate lateral oblique keels, the upper pair 

 joined by a straight transverse keel about one-fourth of the length of the
