jointed, and is furnished with groups of seven -|- four -f- f° ur setae from the apex downwards. 



The maxillipedes are similar in structure to those of Euchirella rostrata. 



The exopodite of the first pair of feet is distinctly three-jointed, and each joint is furnished 

 with an outer-edge seta. The endopodite is composed of one joint. 



The exopodite of the second pair of feet is three-jointed, and the endopodite is distinctly 



two-jointed. 



I'he third and fourth pairs of feet have a three jointed exopodite and endopodite. The 



first joint of the basiopodite of the fourth pair of feet is furnished with a transverse row of fine 



bristles on its inner margin (Plate XIII, fig. 12). 



The fifth pair of feet is absent. 



The whole of the integument, with the exception of that of the mandible-palps, maxillae, 

 and first maxillipedes, is covered with fine granulations. 



O ecu r re nee. — One female was found in plankton collected with the Hensen vertical 

 net at Station 185, 1536 metres to surface.

Female — length 7,5 mm. 



The cephalothorax is oblong ovate and rather robust. The head is distinctly separated 

 from the first thoracic segment. It is without a crest but has a conspicuous one-pointed rostrum. 

 The fourth and fifth thoracic segments are completely separated. The last thoracic segment is 

 produced into small spines, which, when viewed laterally, are seen to be pointed slightly upward 

 (Plate XIII, fig. 15). 



The abdomen is composed of four joints. The combined length of the abdomen and 

 furca is contained three and a half times in the total length of the cephalothorax, from the 

 frontal margin to the base of the genital segment. The genital segment is slightly asymmetrical, 

 being rather more swollen on the right side than on the left. It is longer than broad and 

 exceeds the combined length of the next three segments. The second segment is about half the 

 lenoth of the eenital segment. The third and fourth segments are of about equal length and 

 are about half the length of the second. The furcal joints are about as long as broad, and are 

 as long as the anal segment. The posterior margins of the first, second, and third segments 

 are fringed with fine spines. The whole of the dorso-lateral surface of the abdominal segments 

 and furca, is covered with short hairs. 



The antennules are twenty-four-jointed and extend to the end of the furca. 



The endopodite of the antennae is equal to three-fifths of the length of the exopodite. 

 The apical joint bears eight -J- seven setae. 



The mandibles, maxillae, and maxillipedes are similar to those of Euchirella granulaia. 



The exopodite of the first pair of feet is indistinctly three-jointed. 



The exopodite of the second pair of feet is three-jointed. The endopodite is very 

 indistinctly two-jointed. 



The third and fourth pairs of feet have a three-jointed exopodite and endopodite. The 

 first joint of the basiopodite of the fourth pair of feet is furnished with seven or eight moderately
