resemble those of the figure in the "Proceedings"; the rostrum, 6-times as long as wide in the 

 middle, extends to the distal fourth of the visible part of basal antennular article and the 

 orbital spines are but one-eighth shorter than the rostrum. The carpocerite is perhaps a little 

 less slender than in the other specimen, the two are not equal, the right carpocerite being 4- 

 times, the other 4,4-times as long as wide in the middle; for the rest the antennal region 

 accords with that of the specimen from Stat. 282. The telson fully resembles that of the other 

 specimen. The first pair of legs are missing. Merus of second legs 4,8-times as long as wide; 

 first segment (1,095 rnm.) of the carpus not slender, 3,75-times as long as thick distally, hardly 

 shorter than the sum (1,168 mm.) of the four following, the proportion being 1,07; chela 1,022 mm. 

 long, slightly shorter than the first segment; the fingers in proportion to the palm as 4:3. 



The following legs show a s o m e w h a t stouter form than those of the specimen 

 from Stat. 282 and the propodus of the third pair bears only 6 spinules, instead of 8, but of 

 the same length; those of the fourth pair 7. The dactyli of the third legs are 2,4-times as long 

 as wide at the base and measure about one-fifth the length of the propodus ; the ventral hook is 

 just one and a half as long as wide at base, the dorsal hook is almost twice as long as the 

 other and a little less broad at its base, but for the rest the form of the dactyli is the same 



Ova rather numerous, 0,73 mm. long. 



The slight differences between both specimens are probably of a local or individual character.
