(From a specimen from station fi'i l>.) 



Firs t a n t c u n a: — This is of the type reproduced by G. W. MCl.I.Kl!. The e-bristle 

 is, as far as 1 could discover, bare on the anterior side. The second joint is partly furnished 

 with short spines, the end joints are furnished witli moderately long hairs. The first and second 

 joiiits have numerous small yellowish-brown corpuscles. 



Second antenna: — Of the same type as in (\ lophura. The first joint of the 

 e X o p o d i t e is almost or quite bare. The small end joint on the o n d o p o d i t e is, at 

 least in some cases, rather distinct. A rather 

 short c- or d-bristle is sometimes developed 

 on the second endopodito joint. Between the 

 h-and i-bristles there is a small papilla. The 

 armature of the b-bristle is more powerful 

 than that of the a-bristle. The second endo- 

 podite joint is bare. 



Mandible: — As in C. lophura, 

 but only the long lateral bristle is developed f)n the posterior side of the first endopodite 

 joint, the three medial ones are quite absent. The epipodial appendage is some- 

 times represented by a verruca without any bristle. 



The maxilla, the fifth and seventh limbs, the f u r c a and the upper 

 1 i p are of the same types as in C. lophura. The s i .\ t h 1 i in b is of the t}^e reproduced 

 in my fig. 30 of C. symmetrica. 



The rod -shaped organ varies somewhat; it is sometimes of the same t}'pe 

 as in C. lophura; see the accompanying fig. 1. 



Habitat: — Antarctic () v e a n : 



8. A. E., PI. station 64 b. lat. 48" 27' S.. long. 42" 30' W. ; depth 2-,(l0— (im.; 23. VT. 

 1902: 6 mature females; R. M. S. 294. 



Distribution: — Atlantic Ocean between lat. 31" N. and lat. 43" S. Indian Ocean. 

 My specimens were consequently caught somewhat south of the distributional area stated 

 bv G. W. MliLFER.
