is in the adult female 2Y.-times, in the male almost 2Y.,Ttiraes as long as the terminal joint, a 

 microscopical dactylus seems to be present. According to the original description the peraeopods 

 of the I'-' pair should surpass the external maxillipeds by their last two joints, this is not the 

 case and already negatived by the figure 8 a itself. 



The peraeopods of the 2""^ pair are equal and reach by the chela and one-third to 

 two-fifths of the carpus beyond the antennal scale, while the meri extend as far forward as the 

 antennular peduncle; wrist composed of 25 — 30 joints, terminal joint twice as long as broad, 

 as long as the three preceding combined. Chela nearly twice as long as the last joint of the 

 carpus, fingers two-fifths longer than palm. 



The three posterior legs, that much resemble those of Parap. spinipes (Bate), are very 

 long and slightly increase in length posteriorly; the peraeopods of the 3'^'' pair measure in the 

 male, long 82 mm., (N" 6 of the Table) two-thirds, in the ova-bearing female, long 87 mm., 

 (N° 9 of the Table) three-fourths of the entire length, rostrum included, those of the 4'*^ pair 

 in the male three-fourths, in the ova-bearing female seven-eighths, those of the s'"^ pair, finally, 

 in the male four-fifths, in the ova-bearing female ten-elevenths of that length. The legs of the 

 3^'' pair reach, both in the male and in the female, by the dactylus, propodus and nearly the 

 entire carpus beyond the antennal scale, those of the 4''' pair by the dactylus, the propodus 

 and in the male by three-fourths, in the female eight-ninths of the carpus, the legs of the 5'^ 

 pair, finally, by the dactylus, the propodus and in the male by two-thirds, in the female four- 

 fifths of the carpus. The carpi slightly increase in length from the 3^"^ to the 5'^ pair, the 

 propodi, however, much more, so that those of the 5''^ pair are one and a half or a little more 

 than one and a half as long as the propodi of the 3"^'' pair; the meri, that show nearly the same 

 length in the three legs, are armed with slender distant spines. The dactyli are rather (Fig. 34^', 34^) 

 short in proportion to the length of the propodi, measuring .'/g to Yj., of the latter; 

 they are, however, very slender, terminate in a nearly straight terminal claw (stylopodite), at 

 the base of which a short spine and a few setae are implanted. So e.g. are the dactyli of 

 the 5"^ pair (Fig. 34^) of an adult, ova-bearing female 2,4 mm. long, 11- or 12-times as long 

 as wide at base, the terminal claw (stylopodite), 0,4 mm. long, measures one-sixth the 

 whole length of the joint, while the accessory claw measures only one-third of the terminal. 



The male attains a length of 85 mm. from apex of rostrum to tip of telson, the largest 

 ova-bearing female is 102 mm. long.
