j4 STALK-EYED CRUSTACEA. 



below tVoiii the proximal half tlown between the eye-stalks ; this plate is 

 toothed anteriorly but does not reach forward nearly to the tip of the ros- 

 trum. The antero-lateral margin of the carapace is five-toothed; the second, 

 third, and fourth of these teeth give rise to long thread-like cilia. There is 

 another tooth at the angle between the postero-lateral and posterior margins; 

 posterior niar<rin straight. The upper surface of the eye-stalk is covered with 

 small tubercles, and a blunt spine projects over the cornea. The movable 

 scale of the antenna is spiniform and bears two blunt spinules on the outer 

 side and two smaller ones on the inner. The chelipeds are unequal (the 

 rio-ht being the larger); coxa granulated, setose on the lower inside mjjrgin ; 

 lower margin of the ischium and merus armed with three or four blunt teeth, 

 superior margin of merus toothed, internal distal border setose, external 

 distal border forming a bilobed crest ; outer face of carpus flat, naked, 

 squamous, margins cristate, the internal crest expanded and cut into setiferous 

 lobes ; propodite tuberculated without, smooth within, toothed and setose on 

 superior margin ; immobile finger, as well as the dactylus, excavated within, 

 setose ; the larger claw has blunt teeth on the fingers, while the fingers of 

 the smaller claw have nearly straight cutting edges. The ambulatory 

 appendages have cristiform anterior margins from the merus to the propodite 

 inclusive ; the crest of the carpus is entire or slightly crenate, but that of 

 the merus is bilobed, of the propodite trilobed ; the posterior margins of 

 these appendages are dentate and more or less setose ; two setiferous teeth 

 near the proximal end of the upper face of the merus of the hind legs ; the 

 dactyli are provided with curved, acute, black tips, and with pencils of hair 

 especially on anterior margins. The abdomen is indurated, with three rows 

 of tuberculated plates ; toward the posterior end there is a vestige of two 

 marginal rows of small, imperfectly calcified plates. 



Length of carapace, 16.5 mm., breadth 16.5 mm.
