with 22 segments of which the last is as long as the two preceding ones; chela 0,75 mm. 

 long, palm 0,42 mm., fingers 0,33 mm. Of the Jonger leg the merus is 3,3 mm. long with 

 23 segments, of which the i st is 2 1 /„-times as long as the 2" d ; carpus long 6,2 mm., almost 

 twice as long as the merus and one and a half as long as the carpus of the other leg, with 

 about 50 segments, of which the last is as long as the two preceding together; chela long 

 0,52 mm., palm long 0,28 mm., fingers 0,24 mm. 



The peraeopods of the 3 rd pair reach in the largest specimen by the dactylus, the 

 propodus and four-fifths of the carpus beyond the antennal scale, those of the 4 th by the dactylus, 

 the propodus and the whole carpus, those of the last pair, like the 3 ld , by the dactylus, the 

 propodus and four-fifths of the carpus, while these legs of the 5 th pair project by the dactylus 

 and half the propodus beyond the legs of the 3 rd pair. Like in Nikoides Danae 2 spines exist 

 on the ischium of the 3" 1 and 4 th pair, one near the proximal, one near the distal end; the 

 merus of the 3 ld pair is armed with 4, that of the 4 th with 5 spines ; the last pair of legs are quite 

 unarmed. In the largest specimens the propodus of the 5 th pair is still a little shorter than the 

 carpus, but in the female from Stat. 71 the propodus is one-third longer, like in Nikoides Danae, 

 according to Nobili. The dactyli measure in the largest specimen one-third of the propodi, in 

 the larger female from Stat. 274 they are a little longer, in the female from Stat. 71 a little 

 shorter than one-third of the preceding joint. In the other specimens the three last legs are 

 wanting or incomplete. 



In the ova-bearing female the inner branch of the 2 nd pleopod is 6-times as long as 

 broad, has therefore a rather narrow shape and bears, at the proximal third, a well-developed 

 stylamblys that measures o n e - f i f t h the length of the branch ; the stylamblys is furnished at 

 the tip with about 20 cincinnuli of the usual form and is about 9-times as long as thick; the 

 outer branch has the same shape as the inner and is but a trifle longer. 



Eggs small, numerous, 0,46 — 0,5 mm. long. 



The larger female from Stat. 274, that has been figured, is 25,2 mm. long, from tip 

 of rostrum to tip of telson, the carapace, rostrum included, 8,1 mm. long and 3,5 mm. high, 

 abdomen 17,1 mm. long. 



The ova-bearing female from Stat. 260 was wrapped in a felt-like tube, similarly 

 as Alphcus frontalis H. M.-Edw. ; examined under the microscope, the tube was apparently 

 formed by small particles, Foraminifers, microscopical shells etc.
