petasma, that tooth which is placed next to the triangular prominence, is the longer, shows 

 the same width along its whole length and is curved laterally outward ; the other shorter tooth 

 is curved forward and acute at the tip. 



The other specimens are all much younger and mostly mutilated.

Stat. 212. September 26. 5 54.5 S., I20°I9'.2E. (West of Saleyer-island). 462 m. Bottom fine 

 grey and green mud. 1 female. 



This female bears a Bopyrid in the right branchial chamber. Unfortunately the rostrum 

 is broken at the anterior end of the eyes; the carapace from the orbital to the posterior margin 

 is 20 mm. long, the abdomen 48 mm., so that, when supposing that the rostrum has reached 

 to the far end of 2 nd antennular article, the entire length has been 76 mm. The 3 rd abdominal 

 tergum is obtusely carinated on its posterior half, the carina fading away anteriorly ; the 

 4 th — -6 th terga are sharply carinated. The telson reaches to the posterior 6 th of the inner uropod 

 and to a little beyond the middle of the outer. 



The lower (shorter) antennular flagellum, 25 mm. long, is one-fourth longer than the 

 carapace, rostrum excluded, and a little more than twice as long as the peduncle ; distance 

 between the tip of the antennular peduncle and that of the antennal scale one and a half as 

 long as 3 rd article. 



The 3 rd legs reach nearly by the chela beyond the antennal scale, those of the 4 th pair, 

 60 mm. long, are 3-times as long as the carapace without the rostrum and project by the 

 dactylus, the propodus and iïve-sixths of the carpus beyond the antennal scale-, the peraeopods 

 of the 5 lh pair, finally, are 74 mm. long and reach beyond the antennal scale by the dactylus, 

 the propodus and seven-ejghths of the carpus.

 Stat. 166. August 22. 2°28'.5S., I3I°3'.3E. Midway between Ceram and New Guinea. 118 m. 



Bottom hard, coarse sand. 4 young specimens. 

 1 female collected in 1910 by Mr. KLEIWEG DE ZWAAN at Gunung Sitoli, Nias. 



The female from Nias is 45 mm. long, almost adult. The rostrum (Fig. 2) is 1 + S-dentate 

 and reaches almost to the corneae of the eyes ; the epigastric tooth has nearly the same size 

 as the i st rostral tooth, the following rapidly decrease in size, so that the four anterior teeth
