respectively 23,5 mm., 29,5 mm., 2,5 mm. and 2,75 mm. long. The other legs are wanting-. 

 Telson like in the preceding specimen with 8 pairs of dorso-lateral spinules. 



The largest male from Stat. 122 is full-grown, 93 or 94 mm. long, the carapace, rostrum 

 included, beino- 27 mm. long. The rostrum that measures 7 mm., extends almost to the middle 

 of 3 rd antennular article and is Y-dentate; 5 teeth stand on the carapace, the 6 th above the orbital 

 margin and the teeth are closely placed together; the distance between the foremost tooth and 

 the tip of the rostrum measures one-third of the latter and this unarmed tip is slightly upturned. 

 The tooth on the lower margin is situated midway between the foremost tooth of the upper 

 maro-in and the apex of the rostrum. Sixth somite of abdomen 13,5 mm. long, 5,75 mm. broad, 

 telson 15 mm. long; the telson, faintly grooved longitudinally on the anterior half and flattened 

 on the posterior, is armed with 7 somewhat irregularly planted, dorso-lateral spinules, including 

 those near the tip, and is as long as the outer uropod, when the terminal spinules are excluded. 

 In the second, somewhat smaller male the rostrum runs straight forward almost to the distal 

 extremity of the antennular peduncle and the tip is hardly upturned; the upper border bears 9 

 teeth, four of which are on the carapace, the 5 th above the orbital margin; the teeth are not 

 of the same form and close set like in the preceding specimen, but the penultimate and the 

 antepenultimate tooth are farther distant from one another and from the 6 th , i. e. longer, than 

 the other teeth. The tooth on the lower margin is very small, directed straight forward (not 

 downward as in the largest male) and one and a half as far distant from the tip of the rostrum 

 as from the foremost tooth of the upper margin. In this specimen the legs are also wanting. 



The youngest male from Stat. 122 measures 65 mm., the carapace, rostrum included, 

 being 20,2 mm. long. The rostrum, 5,45 mm. long, resembles that of the preceding specimen 

 and reaches just beyond the middle of 3 rd antennular article; the upper margin is armed with 

 10 teeth, the 5 th stands above the orbital margin, but the penultimate and the antepenultimate 

 tooth are not longer than the rest; apex of rostrum and lower tooth as in the preceding male. 

 Sixth abdominal somite 9,2 mm. long, 4,25 mm. broad; telson 10,25 mm - l° n gi on b' as l° n g 

 as the inner uropod and distinctly shorter than the outer, with 9 pairs of dorso-lateral spinules. 

 The carpus, long 10,5 mm., of the i st pair of legs projects almost by one-third of its length 

 beyond the antennal scale; chela 3,25 mm. long, nearly one-third of the carpus. 



The three males from Stat. 173 are nearly of equal size, almost full-grown. The largest 

 specimen is 80 mm. long, the carapace measuring 24,5 mm., rostrum included. The rostrum, 

 5,45 mm. long, reaches to the far end of 2 nd antennular article; the upper border, slightly 

 concave above the orbital margin, while the tip is not upturned, is armed with 12 teeth, 6 of 

 which stand on the carapace ; the three distal teeth are farther distant from one another, i. e. 

 a little longer, than the rest. Tip of anterior tooth one and a half as far distant from the tip 

 of the rostrum as from that of the penultimate. Tooth on lower margin small, directed forward. 

 The telson hardly reaches by its terminal spinules the tip of the outer uropod. The carpus, 

 long 14 mm., of the i st pair of legs extends by one-third of its length beyond the antennal 

 scale. Other legs wanting-.

The rostrum of the 2 nd specimen, long 78 or 79 mm., resembles that of the first and 

 is also 1 '^-dentate, but the foremost tooth is as far distant from the tip of the rostrum as from
