from Stat. 260 — 6-times as long as broad, terminal spine (Fig. 50/) of the outer margin not 

 reaching beyond the obtuse tij) of the blade and curved toward it. In the specimen from Stat. 71 

 the terminal spine (Fig. 507') projects, however, straight forward beyond the tip of the lamella. 



The external maxillipeds project by the ultimate and almost the whole penultimate joint 

 beyond the antennal scale; the ultimate joint is distinctly shorter than the [penultimate and both 

 together measure a little less than two-thirds of the antepenultimate; the exopodite extends 

 about to the middle of the latter. 



The chelate leg (Fig. 50^) of i st pair agrees with Paulson's lïgure 5/; of Niköides 

 Danae: in the ova-bearing female the merus of this leg that extends by the fingers beyond 

 the antennal scale, is 7-times as long as broad, the carpus, 2 1 / 2 -times as long as thick, measures 

 a little more than one-third of the merus, the palm, finally, almost one and a half as long as 

 the fingers, is slightly shorter than the carpus. According to Nobili's description, however, the 

 merus should be, in Paulson's species, twice as long as the carpus. 



The left simple peraeopod (Fig. 50//) has, unfortunately, not been figured by Paulson and 

 his russian description is unintelligible for me: Nobili's figure 1/, however, of this leg differs 

 much from our species and therefore the latter is described as new. The merus, indeed, appears in 

 the largest specimen from Stat. 260 eight-, but in Nobili's figure only five-times as long as 

 broad in the middle; the carpus, which in this figure appears 2 1 / s -tirnes as long as thick distally 

 and more than half as loncr as the merus, shows in the female from Stat. 260 a much more 

 slender for in, likè the merus, being 4-times as long as thick distally and measures not 

 yet two-fifths the length of the preceding joint; the propodus, finally, in Nobili's figure 

 almost as long as the merus, appears in the specimen from Stat. 260 not yet half as long 

 as the latter. In the younger female from Stat. 274 and in that from Stat. 71 the simple leg 

 is wanting, in the specimen from Stat. 282, which is very young, only 10 mm. long, the 

 propodus appears slightly more than half as long as the merus. In both peraeopods of the 

 i st pair the exopodite reaches almost to the middle of the merus. 



In the ova-bearing female only one leg of the 2 nd pair is preserved. The ischium is 

 6,6 mm. long and bears along the proximal third a dilatation, which is about half as broad 

 as long. Merus 5,3 mm. long, slightly shorter than the ischium, and obscurely subdivided into 

 9 joints, of which the i st or proximal is the longest, measuring one-fourth the length of the 

 joint; the following become gradually shorter, but the last joint is as long as the two preceding 

 together. Carpus 10,5 mm. long, twice as long as the merus and subdivided into 27 annulations, 

 that are short and subequal, except the i st and 2 nd proximal ones that are longer, while the 

 last is as long as the two preceding together. Chela 1,75 mm. long, one-sixth of the carpus, 

 fingers distinctly shorter than the palm which is twice as long as broad. By analogy with the 

 female from Stat. 71 this leg is certainly the shorter one. In the two specimens from Stat. 274 

 the 2 nd legs are lost. In the female, long 18 mm. from Stat. 71, the left shorter leg reaches 

 by the chela and half the carpus beyond the antennal scale, the longer right leg by the chela, 

 the carpus and one-fifth of the merus. Of the shorter leg the merus is 2,1 mm. long and sub- 

 divided into 7 joints, of which the proximal or i st is the longest, twice as long as the 2 nd , 

 while the following are subequal ; the carpus is 4 mm. long, nearly twice as long as the merus,
