198 Cumacea: 26. Campylaspididae, 1. Campylaspis 



Pleon segment 5 with conspicuous transverse impression behind the middle. 

 Antenna 1, 2^^ joint shorter than l^\ 3^ than 2'^'^, flagellum of 4 joints, 

 4**^ twice as long as the very short 1 ^\ 3'^ longer than the long 2"*^, accessory 

 a small oblong joint. Maxilliped 3 with 4^^ joint abnormal, triangular, so 

 strongly expanded on medial side that it is as broad as long, most of the 

 very long distal margin concave and free, the 5*'^ joint attached to its lateral 

 apex. Peraeopod 1, 4*^ joint little longer than 5*^. Peraeopod 2, 1^^ joint 

 longer than 5^^. Peduncle of uropods twice as long as the endopod, which 

 is slightly longer than the exopod. L., y with brood, 6 mm. d unknown. 



Lat. 70" 48' S., long. 91" 54' W., a single specimen.

Pseudorostral lobes shortly and obtusely produced in front of the ob- 

 long oval eyelobe, sinus and antero-lateral corner well marked. Carapace tumid, 

 covered with tubercles more or less symmetrically arranged. Pedigerous 

 segments and pleon segments as in C. horrlda (nr. 16). The imperfectly 

 developed eye, antenna and mouth-organs also agree with the species 

 just named, but the 7^^ joint of peraeopod 2 is comparatively narrower. Peduncle 

 of uropods less coarsely serrate, not nearly twice as long as the endopod. 

 Colour whitish with greenish tinge (G. 0. Sars), all speckled with deep brown 

 or black (A. M. Norman). L. 9 5-5 mm, d 6-5 mm. 



Norway, depths 113 — 565 m; W. coast of Ireland, depth 219 — 570 m; Mediter- 

 ranean, near Capri, depth 200 — 1100 m. 



22. C. nodulosa 0. Sars 1887 C. n.. G. 0. Sars in: Rep. Voy. Challenger, 

 V. 19 pars 55 p. 9, 68 t. 11. 



Integument strongly indurated. Pseudorostral lobes produced obtusely 

 in front of the rather large oval but apparently eyeless eyelobe, sinus and 

 antero-lateral comer well marked. Carapace very large, not overhanging 

 the pedigerous segments, scarcely half the length of the body, without furrows 

 or carinae but more or less symmetrically covered with spaced tubercles. 

 Pedigerous segments somewhat raised dorsally. Pleon segments separated 

 by deep constrictions, lightly carinate laterally without dorsal teeth, the 5^^ 

 with transverse furrow behind the middle. Antenna 1, 2^"^ joint shorter 

 than 1'^*, 3*^ than 2"^^ flagellum of 3 joints, the 'S'^ minute, the minute ac- 

 cessory 2-jointed. Upper lip broadly quadrate, emarginate behind, projecting 

 in front between the 2-jointed 2^^ antennae as a rounded protuberance. 

 Mandibles with long narrow molar, left member with accessory cutting plate 

 and 4 spines, right with 6 spines and no accessory plate. Maxilla 1, with 

 palp long, carrying 2 filaments. Maxilliped 1, with 9 branchial leaflets on the 

 epipod. Maxilliped 2, with 3 spines on the terminal joint, the intermediate the 

 smallest. Maxilliped 3, 4*^ joint with lateral margin produced to a tooth, 

 medial serrate, perhaps in this respect difl"ering from C. maculata (nr. 18). 

 Peraeopod 1, 2°<^ joint not longer than the rest combined, 7*^ about two- 

 thirds as long as 5*^ or 6*1*. Peraeopod 2, 4*^ and 5^^ joints each with 

 l)identate apex (wanting in C. horrida (nr. 16) and C. inaculata (nr. 18), 7^*^ 

 joint equal in length to the 5*^1. Peraeopod 5 wanting, probably only as a 

 juvenile character. Peduncle of uropods slightly serrate on both margins;
