the end; there are usually about five small acute spinules at the 

 apex (varying from i to 9). 



The rostrum is nearly as long as the carapace ; breadth to 

 length is about as i : 3.5. The upper edge curves upward some- 

 what, distally. There is a small median dorsal spine on the cara- 

 pace back of the base of the rostrum and orbits, and a spine behind 

 the eye. The anterior margin of the carapace has four to eight 

 small denticles below the orbit, on each side. The stalk of the 

 antennules is stout, crooked, excavate at base, bent outward 

 distally (pi. 42, fig. 2). The second article has a strong spine on 

 the outer margin near the distal end ; the third article is short, 

 not much longer than broad, distal border obscurely denticulate ; 

 outer flagellum is thickened; the basal acicle is long, lanceolate, 

 and acute. 



The stalk of the antenna is stout ; third article is a little longer 

 than the second (plate 42, figs. 20,, 2a"). The antennal scale is 

 long, wide at base, tapering to an acute tip, it is about three and 

 a half times longer than the third antennal segment, and nearly 

 twice longer than the antennular stalk ; the tip has no differentiated 

 spine nor notch. 



The third maxilliped (pi. 44, figs. 2n'" ; 3"') is elongated and 

 leg-like. Its distal article is long, proportion to that of the pre- 

 ceding article about 2:1; the inner edge is convex, tapered distally 

 to a subacute tip, with a row of about eight or nine acute marginal 

 spines on the distal third of the edge, one of which is apical ; rows 

 on the outer edge. On the surface there are about eight obliquely 

 transverse rows of setae. The penultimate article is short, longer 

 than broad ; its distal end has a transverse row of spines and 

 longer hairs on both sides. 



The legs of the first pair are incurved, rather short, and rela- 

 tively stout, unequal ; the merus and carpus are excavated beneath ; 

 in the larger chela the carpus is large, cup-shaped, broader than 

 long; merus short, stout, with a dentiform lobe on the outer distal 

 angle ; the carpus and propodus articulate at the lower angle, so 

 that the propodus can fold inward obliquely. 



The larger chela is proximally thick, broad ovate, and tapers 

 rapidly distally. The dactyl is wide, rather longer than the fixed 

 finger, with a broad lateral lobe, and with about five denticles at 

 the tip; it bears many hairs distally and along the margin; the 

 fixed finger is bent slightly inward and strongly arched; tip is
