P D is small and slender, 6 mm. long, with 25-30 segments, most of which are about 

 as long as broad; the second-fifth bear strong dorsal projections. P, is 7-8 mm. long, 

 slender, the second-fourth segments with dorsal projections which are not so large 

 as those on the basal segments of P D . P 2 resembles P] but is 15 mm. long, with 40-42 

 segments, which are about as long as broad, the first-fourth with slight dorsal projec- 

 tions. P 3 is similar to P 2 , 12 mm. long. P 4 is similar to P 3 , 11 mm. long. P 6 is similar 

 to P 4 , 11 mm. long. The following pinnules gradually decrease in length to 7 mm., 

 then slowly increase to 10 mm. distally. The carination of the proximal segments of 

 the lower pinnules becomes progressively less and less, disappearing entirely after the 

 tenth or twelfth. 



Notes. One of the specimens from Siboga station 49a has the centrodorsal broad 

 and flat, discoidal, with the dorsal pole 6.5 mm. in diameter, marked with faint 

 radiating lines and pitted in the center. The cirri are XXX, 17-19, 23 or 24 mm. long. 

 The cirri, and in fact the whole animal, are less robust than is the case in the specimens 

 in the type series. The other specimen from Siboga station 49a is slightly smaller, 

 though exactly similar. The dorsal pole of the centrodorsal is 6 mm. in diameter. 

 The cirri are XXVII, 17, 20 mm. long. In these specimens the arm bases, centro- 

 dorsal and cirri are light flesh color, the latter becoming pinkish distally; the arms 

 beyond the second syzygy are bright yellow orange regularly banded with bright red 

 as in C. rubroflava and in C. magnified. 



The specimen from Siboga station 294 has 13 arms. The dorsal pole of the centro- 

 dorsal is 3 mm. in diameter. The cirri are XX, 16, from 20 to 22 mm. long. The 

 three IIBr series are 4(3+4). This example resembles the two preceding, but the 

 centrodorsal is only half as broad, consequently the cirri appear shorter and more of 

 the division series is visible. 



The four specimens recorded in 1911 from Albatross station 5356 had 20, 26 (2), 

 and 27 arms. 



The specimen from Albatross station 5414 is small, with 11 arms about 90 mm. 

 long.
