one and a half as far distant from the 4 th tooth of the basal crest as the 4 th from the 3 rd and 

 the anterior tooth of the upper margin is one and a half as far distant from the penultimate 

 as from the apex of the rostrum. The lower border is armed with 10 teeth, of which those 

 on the middle are more closely set together than the 2 or 3 fïrst and the 2 or 3 last ones; 

 the i st tooth stands just before the 2 nd of the upper margin, the 7 th tooth is paired with the 

 antepenultimate, while the foremost is situated midway between the apex of the rostrum and 

 the anterior tooth of the upper margin. 



The carina of the 3 ld abdominal somite does not commence at the anterior margin, but 

 a Uttle — about 1 mm. — behind it and is at first rather low, though gradually rising to a 

 more compressed carina; the spine of the 3 ld tergum measures one-third the length of the 4" 1 

 somite. The two following somites are dorsally obtuse, the spine of the 4 th tergum is much 

 smaller than that of the 3 rd and measures only one-fifth of it, the spine of the 5 th tergum, 

 finally, is very small, only half as long as that of the 4 lh ; the fine notch on the 4 th tergum is 

 situated at the posterior fifth. The 6 th somite that is unarmed posteriorly, is 10 mm. long, a 

 little more than one and a half as long as the 5" 1 , that measures 6 mm. The dorsal portions 

 of the postero-lateral margins of the 4 th and 5 th somite are spinulose, but the spinules are a 

 little smaller than in Kemp's figure 1 on Plate VI of his work of 1910; the 4" 1 somite has 

 on the left side 6, on the right 7 spinules, the 5 th on the left side 4, on the right 5 spinules 

 and on each side the lowermost spinule or the lovvermost but one is a little larger than the 

 rest. The telson, which is slightly grooved dorsally, except the anterior fourth, is 13,25 mm. long, 

 one-third longer than the 6 th somite, and reaches a little, viz. 0,5 mm., beyond the exopodites 

 of the eau dal fan, when stretched backward. The terminal cluster of spines agrees with Kemp's 

 description of 1910 and there are four pairs on the lateral sides of the telson, the anterior or 

 4 th pair just before the middle, the 3 rd pair as far distant from the 4 111 as from the i st , the 2 nd 

 just midway between the i st and the 3" 1 . 



According to Kemp's description of 19 10 the antennular peduncle should be very short 

 and only reach to about one-third the length of the antennal scale, in the female from the 

 Halmaheira Sea, however, it extends al most to the middle, viz. to 10 / 23 of the length of 

 the scale. The antennal scale, 11,5 mm. long, proves to measure fi ve-se venths the length 

 of the carapace (15,75 mm.), measured between the orbital and the posterior margin, not five- 

 sixths as in the atlantic species. 



The legs of the 3 rd pair are the longest of all and al most reach to the end of the 

 antennal scales, being only 1 mm. shorter ; the propodus (5 mm.) is not "at least three times" 

 (Kemp, 1. c. 19 10), but little more than twice as long as the carpus (2,3 mm.) - - in the 

 4 th l pair these numbers are 5 mm. and 2 mm. - and of both legs the propodus slightly tapers 

 distally in a lateral view. In both the 3 rd and the 4* pair the dactylus measures about four- 

 fifths, not "about two-thirds" the length of the propodus. The legs of the 4* pair reach to 

 the distal third of the antennal scales, those of the 5* pair, finally, are the shortest of all, 

 projecting only by half their dactyli beyond the distal extremity of the carpus of the 4 th pair. 

 General distribution: As already indicated by Mr. Kemp, four isolated specimens, 

 one male, two females, one of which with eggs, and still a fourth specimen have been taken
