In the specimen from Stat. 193 which is here described, the thicker basal part of the outer 

 flagellum consists of 1 1 articles, the two or three distal articles are slightly longer than thick. 

 Carpocerite slender, 6-times as long as thick, a little longer than the antennular peduncle ; the 

 terminal spine, 4-times as long as broad at its base, of the scaphocerite extends to the apex 

 of median antennular article and measures one-fifth the total length of the scaphocerite, while 

 the scale reaches until to the distal third part of median article. 



The measurements of the telson are indicated in Table A. Spinules of the upper surface 

 small, those of the posterior pair measuring one-fourteenth the length of the telson and 

 implanted, like those of the anterior, close to the lateral margins; the latter are emarginate on 

 their proximal half. Outer angles of the posterior margin rather indistinct; the longer internal 

 spinules are a little longer than the width of the posterior margin and measure one-fourth, in 

 the younger specimen from Stat. 1 1 4 even one-third the length of the telson.

The specimen from Stat. 193 has lost both chelipeds, that from Stat. 114 supports still 

 the small one. Merus of the latter 1,4 mm. long and 3-times as long as wide, presenting its 

 greatest width a little before the middle and narrowing more proximally than distally ; upper 

 margin with short setae that become longer toward the rounded distal extremity. Length of 

 the carpus two-fifths that of the merus, the carpus one-third longer than thick or high at the 

 distal end, the thickness or height being in proportion to the length as 3 : 4 ; the upper margin 

 of the carpus is beset with rather long setae and ends, at the outer side, in a small, acute 

 tooth, while a similar tooth, slightly larger, occurs at the distal end of the lower margin. The 

 distal surface of the carpus is concave, embracing the palm, and the distal border of the inner 

 surface is emarginate. Chela 1,93 mm. long, one-third longer than the merus and a little more 

 than 3-times as long as the carpus ; measured in the plane of the fingers, that are but slightly 

 shorter than the palm, the chela appears 3, 3-times as long as high. The distal margin of the 

 outer (lower) surface of the palm carries a small, obtuse tooth near the base of the cutting-edge 

 of the immobile finger. The fingers, the pointed tips of which are crossing one another, sluit 

 close together and the immobile finger appears a little higher at its base than the other. The 

 immobile finger bears a small, tridentate lobe near the articulation, foliowed by a slight 

 emargination of the cutting-edge, while one observes a very small, acute tooth at the distal 

 end of this concavity; the following part of the cutting-edge appears entire, but there are 

 probably still 2 or 3 small teeth near the tip. The dactylus bears a small, acute tooth opposite 

 to the described emargination on the other finger and between this tooth and the tip 7 or 8 

 smaller teeth occur. The chela is fringed with rather long setae, near the upper margin of the 

 palm and dactylus, at the inner side.
