 ones, which are short. Last segment with the median carina 

 ending in a spine, and with four other cannulas on each side 

 of it (including that of the lateral margin) ; marginal spines 

 six. Antennules and antennas very small and slender. Rap- 

 torial limbs with the penultimate joint slender, elongated, 

 and slightly widening at its distal end ; dactyli three-

 apex, which is acute. Fourth to seventh thoracic segments 

 with the lateral processes slightly rounded. Fifth postabdo- 

 minal segment with a small spinule at its postero-lateral 

 angles ; sixth without carinas, but armed with six small 

 spines on its posterior margin, including those of the postero-
