The length of this copepod given by Brady is 5'5 mm.,by fJiesbrecht 4 '9-5 '3 mm. 

 The majority of the ' Discovery ' and 'Gauss' flpecimcnn measure under 5 ram. The 

 cephalothorax is rather over three times as long as the nhdomcn, furcal segments twice 

 as long as broad. Head evenly rounded, without any trace of crest Head separate 

 from first thoracic segment. Last thoracic segment laterally produced a little, and 

 ending in short points. Anterior antenna) not reaching beyond the fun -a (thus shorter 

 than described by Giesbrecht, in these specimens). Relative proportions of 24th to 25th 

 segments as 18 : 21. 



Second feet Re 3 divided into proximal portion 24 : distal 25. 

 Third 20; 23. 



Fourth ,,36: 20. 



Hi3 with seven bristles, end saw two-thirds the length of /?'3. Fifth feet, Ji 1 

 with inner margin convex below, concave distally, with thirteen or fourteen teeth, and 

 distally with three teeth, larger than the others. /?/3 with five bristles, two outer, 

 two apical, one inner. This animal is much more robust than the next special 

 (simillimwi). 



The <J is about the same size as the 9 mid the chief differences consist in the 

 structure of the fifth feet and shape of the head and thorax. The latter is very like C. 

 jinmarchictui, the head oval, rounded, nnd produced, the first thoracic segment with deep 

 indentation l>etween it and the second, and its posterior margin protruded. The 

 anterior antennas with the basal joints much coalesced. Posterior footjaw with a long, 

 stout, densely-feathered dorsal bristle. Fifth left foot much prolonged, /.' 1 and 2 . 

 elongated, Re 3 very short and pyriform shape, with short distal bristle. Ri only half 

 the length of Re, with respectively 1:1:6 short weak bristles. Right foot Ri nearly 

 as long as Re, with 1:1:6 bristles, lie not much more than half as long as St at 

 opposite side. First basal with inner margin armed with seventeen to twenty large 

 teeth ; in its upper part slightly concave, in its lower part slightly convex, the teeth 

 all of pretty much the same size.
