Cumacea: 3. Bodotriidae, 8. Heterocuma, 9. Cumopsis 49 



Pseudorostral lobes blunt, i-eaching little beyond the eyelobe; antero- 

 lateral corners obtuse, especially in the d, and not reaching level with apices 

 of pseudorostrum. Carapace not elongate, smooth except for median carina 

 which is flanked by shallow depressions in front half and becomes doubled 

 in the hinder half. First pedigerous segment only exposed dorsally, this 

 and the rest devoid of carinae, 3^ and 4^^ segments in the d with strong 

 lateral articulation. Pleon segments with feebly developed medio-dorsal and 

 lateral carinae, telsonic segment with dorsal depression. Eyelobe little longer 

 than broad, with large dark eye. Antenna 1 stout, 1^* joint as long as 2°^ and 

 b'^ combined, 3'^ a little longer than 'A""^. Mandibles with many spines in 

 spine-row. Maxilla 1 with 2 apical filaments to the palp. Maxilliped 3, 2°'! 

 joint with medial margin produced into a short tooth. Peraeopod 1, 2''^ joint 

 a little shorter than rest of limb, with a pair of stout spines on medial edge 

 near the base, and medial margin distally produced into a small tooth. 

 Peraeopod 2, 2^^ joint with setose stiliform exopod extending just beyond it, 

 the next joint absent or coalesced. Peraeopod 3, 2°^ joint with similar exopod 

 not extending beyond its middle. Peduncle of uropods slightly shorter than 

 exopod, subequal to the endopod, which is setose on the lateral margin, the 

 longer P"^ joint, like the rather shorter and much narrower 2»^ carrying about 

 a dozen spines successively larger towards the abruptly larger apical spine. 

 L. d adult 18 mm, 9 immature 17 mm.

Like H. sarsi, but carapace dorsally carrying small tuberculiform 

 granules, largest along the median carina, gradually disappearing towards 

 the lateral margins; first 5 pleon segments with strongly marked dorsal, 

 dorso-lateral and lateral pairs of carinae, and a feeble ventro-lateral pair; 

 the appendages, especially the l-"* peraeopods and the uropods a little more 

 elongated.

Pseudorostral lobes little produced. All five pedigerous segments distinct. 

 Telsonic segment not produced between the uropods. Eye well developed. 

 First antenna of d with dense whorl of filaments round swollen ])ase of 

 the flagellum. Third maxilliped with second joint not apically produced. 

 Second and third peraeopods with very small setiferous exopods. Pleopods 

 with process on lateral margin of the endopod. Uropods elongate, endopod 

 2-jointed, first joint longer than second, first joint of exopod rather long. 

 Hepato-pancreatic glands with two pairs of lobes. 



2 species.
