The adult male from Stat. 282 is 16 mm. long, the adult ova-bearing females 17111111. 

 In this male the rostrum hardly reaches beyond the middle of the visible part of i st antennular 

 article, the orbital spines that are barely shorter, are slightly curved inward. The 2 nd antennular 

 article (1,4 mm.), appears, as also in other specimens, a little more than twice as long 

 as the visible part (0,62 mm.) of the i st , which is as long as the 3 ld . Spine on the basicerite 

 reaching to the extremity of i st antennular article; the scaphocerite, the outer margin of which 

 is concave, is a little shorter than the carpocerite, which just reaches beyond the extremity 

 of the antennular peduncle. Carpal segments of the larger (right) leg of the 2 nd pair 1,6 mm., 

 1,2 mm., 0,5 mm., 0,6 mm. and 0,8 mm. long, chela 1,4 mm. long (palm 0,6 mm., fingers 

 0,8 mm.); in the left leg the 5 th carpal segment appears not shorter than the 2 nd . 



Merus of 3 rd legs 3,3 mm. long, 1 mm. wide in the middle, 3,3-times as long as wide; 

 posterior margin with 6 movable spines (in the females with 5, in younger specimens with 4 or 3) 

 and with a much larger, subapical, acute tooth, anterior margin with a long seta at the distal 

 third and with a few setae at the far end. Anterior margin of the carpus setose, terminating in 

 an acute tooth; posterior margin with 2 small, movable spinules in the middle (in the female 

 often with one, or with two inserted abreast, in young specimens also with one) and with 4 

 similar spinules at the distal extremity, the two inner spinules somewhat larger than the outer. 

 Propodus 2,16 mm. long, about two-thirds of the merus, 4-times as long as broad in the middle; 

 posterior margin with 6 pairs of spinules, anterior setose. Accessory claw of dactylus shorter 

 than the principal one. 



In the adult female from Stat. 93 the 2 nd antennular article (1,3 mm.) appears almost 

 twice as long as the visible part (0,7 mm.) of the i st ; carpocerite distinctly longer than the 

 antennular peduncle, which obviously reaches beyond the tip of the scaphocerite. In an adult 

 female from Stat. 282 the scaphocerite reaches to the end of the carpocerite, which is hardly 

 longer than the antennular peduncle. 



In the adult female from Stat. 78, like in other specimens, the 2 nd antennular article 



appears one and a half as long as the visible part of the i st , just as is indicated for this 



species by Stimpson and Ortmann. The scaphocerite appears as long as the antennular peduncle 



and hardly shorter than the carpocerite. The rostrum, reaching to the middle of i st article, is 



longer than the orbital spines.
