lum., 3.9 : 1 (Alaska station 29); 2.57 mm., 3.7 : 1 {Gill station 62) 

 2.06 nmi. {Gill station 6). Adult male: allotype, 2.49 mm., 3.4 : 1. 



Diagnosis: Adult female; similar to C. longimana (Claus) with 

 respect to cophalothorax, cephalic appendages, and swimming legs 

 1-4 (fig. \,ej,h,k-n). 



Abdominal details differing from longimana: Genital segment with 

 somewhat angular lateral swellings, greatest width anterior to mid- 

 length of swellings (fig. 1,*^/,^^); measured at greatest width, genital 

 segment wider than long (0.82-0.85 : 1); second abdominal segment 

 produced ventrad in a broad lobiform process (fig. 1 ,c) ; process extends 

 ventrad and somewhat anteriad, almost reaching posteroventral 

 margin of genital segment. 



Fifth legs differing from longimana; spines of ramal segment small; 

 ramus with two apical subcqual spines, two appressed spines along 

 lateral margin; medial margin of ramus with longitudinal row of 

 about five small denticles near apex (fig. l,i,j). 



Adult male similar to longimana Avith respect to cephalic a])pendages 

 and swimming legs 1-5. 



Posterior process of right fifth thoracic segment relatively longer 

 and of rather different form than that of longimana. Seen from above 

 (fig. 2,c) process tapers graduall}^ and turns slightly outward at tip; 

 in lateral view (fig. 2,6) it curves upward to tip, which has an expan- 

 sion on its posterior side. 



Genital segment (fig. 2,a,d) similar to that of longim,ana, but 

 process on right side without thickening near the middle as charac- 

 teristic of longimana. 



Fifth legs (fig. 2,e) like those of longimana in all details.
