long as carapace and abdomen combined. Antennal peduncle a little longer than the basal joint 

 of that of the upper antennae, scaphocerite (Fig. 27^) almost as long as the carapace (in the female 

 9 mm. long), slightly more than 4-times as long as wide, distinctly narrowing anteriorly, outer 

 margin slightly concave proximally, terminal spine distinctly reaching beyond the truncate tip 

 of the lamella. 



The external maxillipeds reach by their terminal joint and one-fourth of the penultimate 

 beyond the antennal scale; exopodite small, not yet reaching to the middle of the antepenul- 

 timate joint. 



The peraeopods of the p' pair reach by four-fifths their terminal joint (or propodus) 

 beyond the external maxillipeds; the penultimate joint or carpus is almost twice as long as the 

 terminal, these joints being respectively 9,1 mm. and 5 mm. long in the adult female: a 

 micro.scopical chela seems to be present. 



The slender legs of the 2"'' pair are equal and reach by the chela and two-fifths of 

 the carpus beyond the antennal scale, while the merus extends to the far end of the antennal 

 peduncle; in the adult female the carpus, which is composed of 19 or 20 segments, is 9,8 mm. 

 long, as long as the carapace, and the chela, the fingers of which have the same length as 

 the palm, is 1,6 mm. long, one-sixth of the carpus. 



In the adult female the legs of the 3"^^' pair reach b\- the dactylus, the propodus, the 

 carpus and one-fifth of the merus beyond the antennal scale, the merus of the 4''' pair reaches 

 almost to the distal extremity of the antennal scale and the legs of the 5''' pair reach ,by the 

 dactylus, the propodus and four-fifths of the carpus beyond the scaphocerite. At the right side 

 the 4'** and the 5'*^ legs are complete, but in those of the 3"^'^ pair the propodus and the dactylus 

 are wanting; on the left side the y^ leg is wanting and the dactylus of the 5'''. The meri 

 diminish regularly in length from the 3''^' to the 5''' and those of the 3'^' pair are distinctly 

 thicker than the meri of the 4''' and 5'''; the meri are spinose, like in the allied species, but the 

 number of spines is small. The same regularity does not exist in the carpi, for the carpus ot 

 the 4''^ leg is distinctly shorter than that of the 3"^'^, but the carpus of the 5''> pair is longer 

 than that of the preceding leg. The propodi, however, probably increase regularly in length, for 

 those of the 5''' pair are longer than the propodi of the 4''' and in the allied /'/es. ocelhis (Bate) 

 the propodus of the ^^^ pair is shorter than that of the 4'''. The dactyli are very short, 

 measuring in the 4''> pair (Fig. 2 ye) about Yj,, in the 5''' (Fig. 27^^) Yi; the length of the propodi; they 

 are of a stout shape, 5-times as long as broad at base both in the 4'*^ and in the 5''^ pair, and their 

 posterior margin is unarmed, without .spinules, except one or two near the tip. In the adult, 

 full-grown female the carpus of the right 4"^ leg is 12,3 mm. long, the propodus 11,3 mm., the 

 dactylus i mm., for the left leg these numbers are in the same succession 10,7 mm., 10,4 mm. 

 and 1 mm.; the carpus of the right 5''' leg is 12,8 mm. long, the propodus 13,6 mm., the 

 dactylus 0,9 mm., in the left leg these numbers are in the same succession 12,75 "'""• '^'''d 

 1 3 mm. (the dactylus is lost). Attention may also be called to the fact that the measurements 

 of carpus and propodus differ rather much in the two legs of the 4''' pair. In the male, which 

 is much smaller, the three posterior legs are lost. 



The male from Stat. 95 has nearl\- the same size as tlial from Stat. 253. The extreme
