o-bristle. The first and second joints are partly furnished with fine spines. These joints have 

 yellowish-brown corpuscles. 



Second antenna: — The p r o t o p o d i t e is rather slightly weaker than in 

 the male. The cxopodite is relatively somewhat shorter than in the male, but is otherwise 

 the same. Endopodite: This is rather distinctly three-jointed. The f- and g-bristles 

 are of about the same type and relative size as in the male or only rather slightly shorter. The 

 h-, i- and j-bristles are in most cases relatively somewhat shorter than in the male; in most cases 

 they have no distinct shafts and are furnished proximally with short, fine spines. The f-bristle 

 too is furnished with short hairs more often than in the case of the male. Between the h- and 

 i-bristles there is sometimes an exceedingly small papilla, but in most cases it is qiute absent. 

 The second endopodite joint is bare. 



R o d - s h a p e d org a n: — The stem extends in most cases about as far as half 

 the length of the capitulum beyond the point of the first antenna. The capitulum is of the type 

 described by G. W. MULLER (see the accompanying fig. 10) and is about one and a half times 

 or twice as long as the second joint of the first antenna. 



Remarks: — The larvae investigated by me belonged to Stages I — III. They me^isured 

 3,05—3,3 mm., 2,05—2,2 mm. and 1,3—1,35 mm. 



Habitat: — Antarctic Ocean: 



S. A. E., PI. station 34 b, lat. 46«45' S., long. 58« 2' W.; depth, 700— 500 m.; 28. XII. 

 1901: 1 juvenis of Stage III. S. A. E., PI. station 64 b, lat. 48" 27' S., long. 42° 36' \V.; depth, 

 2500 — m.; 23. VI. 1902: 24 mature males, 43 mature females and 54 juvenes; R. M. S. 

 308—311. S. A. E., PI. station 70 b, lat. 49" 56' S., long. 49" 56' W.; depth, 2700— 1» m.: 

 27. VI. 1902; temperature at 2700 m. and at the surface, -f 1,67" ('. and 3,40" C . resp.: 3 mature 

 males, 1 mature female and 14 juvenes; R. M. S. 312. 



Distribution: — South Atlantic Ocean and Antarctic Ocean between the equator and lat. 

 54" S. Indian Ocean. 



The three stations of tlie ,,A n t a r c t i c" expedition are consequently situated within 

 the area of distribution stated by 0. W. .Mi l.i.i;i;. 



Alata group G. W. Muller. 



With regard to this group I hold (|uite tin- ^amc view as has been put forward by 

 G. W. Mil-LliK, 1906a, p. 121. It may be taken as (|nitc ccit.iin that ('. Iklgime belongs to it.
