is in the adult female 2 1 / s -times, in the male almost 2 1 /.,-times as long as the terminal joint, a 

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

 of the i st 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 nd 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 rd pair measure in the 

 male, long 82 mm., (N° 6 of the Table) tvvo-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" 1 pair 

 in the male three-fourths, in the ova-bearing female seven-eighths, those of the 5 th pair, finally, 

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

 3 rd 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 th 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 th 

 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 rd to the 5 th pair, the 

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

 than one and a half as long as the propodi of the 3" 1 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 1 L to l /- i „ of the latter; 

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

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

 the 5 th pair (Fig. 346') 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-.
