Of the two teeth with which, in both specimens, the rostrum (Fig. j, ja) is armed, the posterior 

 appears slightly longer and a little more slender than the anterior and the distance between their 

 apices is nearly t w i c e as large as the distance between the apex of the anterior tooth and 

 that of the rostrum ; the distance between the apex of the rostrum and that of the posterior 

 tooth measures about one-sixth the length of the carapace, rostrum included. Supra-orbital and 

 hepatic spine well-developed, of equal size, larger than the small branchiostegal spine. 



Abdominal terga rounded, their posterior border truncate, excepting the 6 th somite 

 which is laterally strongly compressed, the upper margin, however, not carinated and terminating 

 in a short acute spine; the 6 th somite, 2,36 mm. long, is twice as long as broad and a little 

 more than twice as long as the fifth. Telson 1,76 mm. long, three-fourths the length of the 

 6 th somite, somewhat shorter than the inner uropod, that is almost as much shorter than the 

 outer; there are still only four pairs (Fig. jb) of small marginal spinules. 



The eye-peduncles, namely their terminal joint, measure a little more than one-third the 

 length of the carapace and the diameter of the globular eye measures one-third the length ot 

 the peduncle. 



The acute spine (stylocerite) on the outer margin of basal antennular article, a little 

 behind the middle, is well-developed, like also the spine at the distal extremity, which is 

 directed outward, while the third spine, that rises from the upper surface just in front of the 

 statocyst and behind the stylocerite, is quite conspicuous in a lateral view (Fig. ja) of the animal. 

 Second joint in the female 0,42 mm. long, 0,24 mm. broad, proportion between length and 

 width like 7:4; 3 ld joint a little shorter, 0,3 mm. long and twice as long as wide in the middle. 

 Both the inner and the outer margin of the i st and 2 nd antennular article are fringed with 

 rather long setae, shorter setae occur also on the inner margin of the 3 rd article ; in both 

 specimens the 3 rd article reaches by one-third its length beyond the antennal scale. Outer 

 flagellum thickened at base, the thickened part 0,5 mm. long and with sensory filaments along 

 its whole length. Second antennal article with a spine, which is nearly of the same size as the 

 branchiostegal spine, antennal peduncle reaching as far forward as the stylocerite, a little 

 shorter than the eye-peduncle and of a stout shape, the terminal joint twice as long as broad; 

 flagellum in the female 15,7 mm. long, only one-sixth longer than the body, with the abrupt 

 doublé bend at three-sevenths of its length from the base, like in the male, long 20 mm., 

 described by Dr. Calman in 191 3, but in this male the flagellum was more than twice as long 

 as the body, owing to it being adult. 



In both specimens the third maxillipeds are still only one-fifth longer than the carapace 

 owing to their young age and reach only as far forward as the antennal scale. In neither 

 specimen (Fig. je) I did succeed in observing the subdivision of the two 

 distal segments, which for the rest agree with Calman's figure 9 in his paper of October 

 191 3. In the male the antepenultimate segment is 0,7 mm. long, the penultimate is just as 

 long, while the terminal joint is a little shorter, measuring 0,5 mm. 



The peraeopods of the i st pair (Fig. jd) reach to the anterior border of the carapace, carpus 

 0,5 mm. long, chela 0,62 mm. long, 5-times as long as wide, fingers little shorter than palm. 

 The peraeopods of the 2 nd pair (Fig. je) extend to the far end of the antennal peduncle, their merus
