The form, however, referred by Miss Ratiiuln (1. c.) to Proc. processa, belongs in my opinion 

 to another species on account of the much larger number of carpal segments and of the eyes 

 being- furnished with a small but distinct ocellus. 



The young male from Stat. 4 is only about 9 mm. long. The merus of the left simple 

 foot (the right chelate leg of the 1"' and 2"'' pair and the legs of the 4''' and 5''' pair are lost) 

 is I mm. long; the carpus, 0,36 mm. long and 0,14 mni. thick distally, has a stouter shape than 

 in the preceding specimen, like also the propodus, which, 0,52 mm. long, is but 3-times as long- 

 as broad. Proportion between merus and carpus of the left leg of the 2"^^ pair like 3:5; carpus 

 (Fig. 52/) with 10 segments, which, e.xcepting the i"' and the last, are about as long as thick: 

 the chela measures one-fourth of the carpus and has a stouter shape than in the preceding 

 specimen, being only twice as long as broad, fingers a little shorter than palm. As results 

 from the J able of Measurements the dorso-lateral spinules of the telson are situated more 

 backward than in the specimen from Stat. 193, with which it agrees for the rest. Kndopodite 

 of 2"<^ pleopod a little shorter than the outer branch, bearing at the posterior third a stylamblys 

 and an ai>pendi.'>c masculiiui; the latter, implanted between the branch and the stylamblys, has 

 4 setae on the tip, while the slightly shorter stylamblys is provided with distinct cincinnuli. 



The egg-bearing female from this Station is hardly 12 mm. long and has lost all the 

 peraeopods, excepting the right chelate leg of the 1*' and the right leg of the 2'"' pair. The 

 chelate leg of the i^' pair shows the same measurements as the specimen from Stat. 261, that 

 belongs to the same species as the male from Stat. 4 and the leg of the 2'"' pair agrees in 

 its measurements with the left leg of the 2°^ pair of this male, but the 9 segments of the 

 carpus are distinctly longer than thick and the chela is a little more than 3-times as long 

 as broad in the middle, presenting a less stout shape than in the male. The telson also 

 differs from that of the male by its more slender form and by the dorso-lateral spinules 

 being implanted like in the female from Stat. 193, with which is seems to agree for the rest, 

 the rostrum .being little shorter than the eyes, while the 2°'^ joint of the antennular peduncle 

 is 3-times as long as thick and one and a half as long as the 3'''. Larger diameter of the 

 eggs 0,4 mm. 



The egg-bearing female from Stat. 96 has nearly the same size as the young niale from 

 Stat. 4. The carpus (Fig. 52^) of the left leg of the 2"' pair has 12 segments that resemble those 

 observed in the young male from Stat. 4, but the chela is 3 -times as long as broad and the 

 fingers are nearly as long as the palm. The right leg of the 2'"' pair is hardly longer than 

 the left, has likewise 12 segments in the carpus and resembles also in other respects its fellow. 



The specimen from Stat. 104 is about 12 mm. long; it is much damaged, having lost 

 all its legs excepting one of the 3"' pair. This specimen belongs without any doubt to the same 

 species as the 'female trom Stat. 4, presenting the sanie form of telson, the .same position of 

 the dorso-lateral spinules, the same form of antennules etc. 



The specimen from Stat. 154 (F'ig. 5 2y', 52/t) is little longer than the egg-bearing female 

 from Stat. 96 and belongs perhaps to a third species. The pleura of the 5''' somite (Fig. 52/) 

 bear namely a sniall tooth posteriorly and the dorso-lateral spinules of the telson (Fig. 52;«) 

 are placed more backward. The carpus (Fig. 52^) of the left leg of the 2'"' pair, almost twice
