19H Cumacea: 26. Campylaspididae, 1. Campylaspis 



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

 circular eyelobe, antero-lateral corners obsolete below a faintly indicated sinus. 

 Carapace very large, boldly arched, dorsal surface anteriorly undulated, lateral 

 faces deeply sulcate between 2 projecting carinae which extend obliquely from 

 the most prominent part of the branchial region to the base of the pseudo- 

 rostral projection. Pedigerous segments 1. 2, elevated to procurved lamellae. 

 Eye apparently having 4 lenses. Maxilla 1, palp with 2 filaments. Maxilliped 1, 

 terminal joint extremely small. Maxilliped 2, terminal joint with 4 diver- 

 ging spines. Maxilliped 3, 4*^ joint not nearly as long as 2 following joints 

 combined. Peraeopod 2, 7^^ joint longer than 2 preceding joints combined. 

 The '6 following pairs with medial margin of 5*^ joint serrate. Peduncle of 

 uropods with medial margin serrate, nearly twice as long as endopod, and 

 fully twice the exopod. Colour whitish, middle tinged with red. L. Q 4-5 mm, 

 d 5 mm.

Pseudorostral lobes shortly produced in front of the linguiform eye- 

 lobe, truncate, sinus and antero-lateral corners small but definite. Cara- 

 pace large and tumid, surface uneven with conical protuberances dorsally 

 crowded, laterally in 2 longitudinal rows, the lower forming an almost contin- 

 uous carina, both connected in front by a transverse prominence continued 

 on the side of the pseudorostral projection. Pedigerous segments 1, 2, raised 

 to thin lamellae, 3'^ to 5^'* of these and first 4 pleon segments each with 

 dorsal pair of adjacent tubercles and sides acutely produced. Eye imper- 

 fectly developed. Maxilla 1, palp with 2 filaments. Peraeopod 2, 2"^ joint much 

 more than half as long as the rest of the joints combined, 7^^ joint subequal 

 to the b^^\ Peduncle of uropods coarsely serrate on both margins, about 

 two and a half times as long as the endopod. Colour dark-red. L. 9 about 

 6 mm, d nearly 7 mm.

Closely resembling C. horrida (nr. 16) but pseudorostral lobes strongly 

 curved downwards to the acute apex, meeting in front of the very small 

 eyeless eyelobe for a distance thrice its length; the dorsal surface of the 

 carapace with only few tubercles; the 5^^ pleon segment carrying a pair of 

 dorsal tubercles; peraeopod 2 with the 2"^ jq^^^ q^Ij j^alf as long as the 

 rest of the joints combined, the 5^^ joint little longer than the 4**^, the 

 7*^ as long as 4:^\ ^^^, and 6^'» combined. L., 9 with rudimentary oostegites,
