Cumacea: 3. Bodotriidae, 1. Cyclaspoides, 2. Eocunia 19 



Pseudorostrum acute, with antero-lateral corner rounded, denticulate. 

 Carapace a little compressed laterally in front, to the rear embracing the 

 first three pedigerous segments, with one dorsal suture or none. Intestine 

 anteriorly coiled, as in Platycuma holti. Body 

 without spinose armature. Telsonic segment subequal 

 in length to the preceding, well produced between 

 the uropods. Eye wanting. Antenna 1 very short, 

 its single flagellum consisting of 2 very small joints. 

 Spine-row of mandible of 15 components. Palp of 

 maxilla 1 ending in a single filament. Exopod of 

 maxilliped 1 very elongate. Maxilliped 3 with 2"'^ and 

 4*^ joints produced along lateral margin of 3*^ and Fig. is. 



5*^ respectively. Peraeopod 1 with joints 5— 7 sub- c. sarsi Bonnier ((j juv.). 

 equal. Peraeopod 2 6-jointed, small. Pleopods 1 — 5 



d with rami as long as the peduncle. Uropods with peduncle slightly shorter 

 than exopod, equal to endopod, which has 5 spines on medial margin and 

 2 apical. L. 5 mm.

Carapace broad in Q, usually narrow in d', with projecting lateral 

 cornua in both sexes. First pedigerous segment ajid at least sometimes the 

 second firmly united with the carapace. Antenna 1, accessory flagellum 

 very small or obsolete. Antenna 2 of 9 with or without a minute 2"^ joint. 

 Peraeopod 1 with 2"*^ joint distally produced acutely forward or inward. 

 Peraeopod 2 6-jointed. Uropods with peduncle much shorter than the sub- 

 equal rami, endopod 1 -jointed.
