corncae ; the flagellum (in the tonialo) is about half tlic length 

 of the body and is fringed with long hairs. 



The chelipeds are equal, their length being about equal to 

 that of the abdomen and their upper surface being hairy 

 throughout ; the ischium and merus, which togctlier make up 

 nearly iialf their total length, meet together from opposite 

 sides in a perfectly straight line across tlic mouth-parts, the 

 line of apposition being closely and sharply toothed. Except 

 for this line of teeth and for a few hardly distinguishable 

 roughnesses on the upper border of the short carpus and of 

 the long cylindrical ])ropodite the surface of the chelipeds is 

 smooth, the propodite being also highly polished. 



The second and third thoracic legs are not much longer 

 than the chelipeds ; the propodite in both is subcylindrical 

 and a little more than twice the length of the dactylopodite, 

 and in both all the joints are smooth, with the margins hairy. 



The fourth and fifth legs are subchelate, the cheliform parts 

 are swollen and hairy, and the propodites have the usual 

 beaded patch. 



The abdominal appendages (in the female) conform to the 

 type ; the appendages of the penultimate segment have the 

 dorsal surface of both exopodite and endopodite covered with 

 a pavement of bead-like granules arranged in close rows, 

 resembling a stridulating organ. 



Colour in the fresh state dull chalky red. 



A female 28 millim. long was dredged at Station 116 in 

 405 fathoms.
