rugose on either side of the median carina, but these rugosities e.xist also in the typical 

 specimens, where they are concealed by the tomentum. 



Eyes (in spirit) of a drab colour. 



Antennular peduncle reaching by one-third the terminal joint beyond the antennal scale. 

 Antennal scale (Fig. 5S«) üke in the adult female from Stat. 74, though still more regularly 

 rounded at the tip, 8 mm. long and 5 mm. broad. 



When the three posterior legs are compared with those of the male and adult female 

 from Stat. 74 or with those of the adult female from Stat. 38, the carpus appears shorter 

 in proportion to the merus, and especially with regard to the propodus. So e. g. the merus, 

 carpus and propodus of the 5 th leg (Fig. 55^) are, in the female from Stat. 85, respectively 

 10,3 mm., 4,3 mm. and 7 mm. long, in the male from Stat. 74, however, 10,5 mm., 5 mm. and 

 6,25 mm., in the adult female from the same Station 13,5 mm., 6,5 mm. and 7,75 mm. 1 ); 

 probably this difference should, however, be attributed to the younger age of the female from 

 Stat. 85, because the same difference exists in the young female from Stat. 38 and in the very 

 young specimen from Stat. 45 : in the young female from Stat. 38 these numbers are namely 

 6,5 mm., 2,3 mm. and 4 mm., in the specimen from Stat. 45 3,8 mm., 1,1 mm. and 2,72 mm.

Stat. 45. April 6. 7°24'S., n8°i5'.2E. North off Sumbawa. 794 m. Bottom fine grey mud, 

 with some radiolariae and diatomes. 1 full-grown egg-laden and 2 young females. 



Stat. 161. Aug. 17. i° io.'s S., 130° 9' E. East of Kofiau-island. 798 m. Bottom muddy sand. 

 2 adult males. 



Stat. 314. Febr. 17, 1900. 7 36' S., U7°30'.8E. North of Sumbawa. 694 m. Bottom fine, sandy 

 mud. 18 male and 32 female specimens, among which one full-grown ova-bearing 

 female, while the rest are nearly all of medium siae and young. 



In the larger male from Stat. 161 carapace and rostrum, taken together, are 40 mm. 

 long, the abdomen 54 mm., entire length 94 mm., while the largest specimen, obtained by the 

 "Challenger", measured 82 mm. and that, which was described by Col. Alcock, 75 mm.; the 

 rostrum, 18,5 mm. long, is more than three-fourths the length of the rest of the carapace. In 

 the ova-bearing female from Stat. 314 the carapace, rostrum included, is also 40 mm. long, 

 the abdomen 55 mm., entire length 95 mm.; rostrum also 18,5 mm. long. Unfortunately in the 

 ova-bearing female from Stat. 45 the rostrum has an abnormal form and is evidently regenerated, 

 the carapace without the rostrum is 25,5 mm. long, the abdomen 61 mm.; taking for the rostrum 

 the same relative length with regard to the carapace as in the preceding specimens, it has 

 originally been 22 mm. long, so that the entire length of this female may be fixed on 108 mm.
