wide, the merus stouter than in the typical form ; propodus with 6 spinules, that are 

 0,146 mm. long. 



Ova ó,S — 0,82 mm. long. 



The largest of the four specimens, the ova-bearing female, is 14 mm. long. 



The largest specimen from Kur-island is the ova-bearing female, long 10 mm.; the eggs 

 are larger than those of the described specimens from Stat. 129, viz. 1 — 1,1 7 mm. long. These 

 specimens resemble the preceding, but the second legs have a stouter form, probably due to 

 their smaller size : the merus is 5,4-times as long as wide, the first segment of the carpus 

 4,4-times as long as thick, the third slightly longer than the second, the chela twice as long 

 as the 5 th segment and the third segment appears a little larger than the second. The relative 

 dimensions of the third legs are: carpus 1 ; merus 1,98; propodus 1,72; these joints, like also 

 the dactylus, have the same form as in the preceding specimens. 



The eggs of the female, long 12,5 mm., from Stat. 37 are 0,73 mm. long; though the 

 legs are missing, it seems to belong to the same variety as the specimens from Stat. 129. 



The two young individuals from Stat. 34, finally, approach to the typical species which 

 occurs in the Maldive and Laccadive Archipelagoes, by the more slender form of the 

 meri of the third and fourth legs. The relative dimensions of the third legs are, in the younger 

 specimen, which is 8 mm. long: carpus i; merus 2,16; propodus 1,9; the merus is 3,86-times, 

 the propodus 6,3-times as long as wide and there are 6 propodal spinules.

Together with the two specimens of the new variety halmaherensis, an ova-bearing 

 female was collected at the same Station, which is referred to the variety prolatus Cout. with 

 much doubt not only because a proper description of this variety does not exist, as far as I 

 know, but still more because this specimen does not fully accord with the quoted figure 7 of 

 Coutière's paper, on which this form is represented.
