flagellum about as long as the peduncle and composed of twelve to 

 sixteen segments. Antennae a little longer than the antennulae ; 

 ultimate and penultimate segments of the peduncle sub-equal in 

 length ; flagellum slightly shorter than the peduncle and composed 

 of eleven to fifteen segments. First epimeron (figure 1) as broad as 

 high ; second (figiu-e 2) broader than high ; third (figure 3) and 

 fourth not broader than high and successively deeper than the first 

 and second ; fifth (figure 4) slightly deeper than the fourth and its 

 terminal portion as broad. In the first legs (figure 1), the carpus 

 longer and broader than the propodus, which is somewhat oval and 

 twice as long as broad ; the dactylus slender, slightly curved and 

 fully as long as the propodus. The inferior distal margin of the pro- 

 podus is regularly curved to a short distance from the extremity, 

 where there is a small but deep emargination, beyond which and 

 round upon the short distal margin the edge is serrate with minutely 

 crenulated teeth ; the posterior margin is furnished with numerous 

 slender seta? and with a single stout spine at the emargination near 

 the distal end. The inner edge of the dactylus is armed with a series 

 of acute teeth directed obliquely toward the tip. In the second pair 

 of legs (figure 2) the propodus is very stout, about twice as long as 

 the epimeron and scarcely one-half longer than broad ; the palmary 

 margin oblique and armed near the middle with two stout obtuse 

 teeth ; the dactylus stout and its inner edge sinuous. Third (figure 

 3) and fourth pair of legs alike ; ischium and carpus short, each 

 nearly or quite as broad as long; merus fully as long as the epimeron 

 and half as broad as long ; propodus slender, not more than half as 

 broad as the carpus but twice as long ; dactylus slender, about half 

 as long as the propodus. Basal segment in the fifth legs (figure 4) 

 squamiform, oval, nearly as broad as long and with a mai-ked angular 

 emargination at the inferior posterior angle ; carpus only slightly 

 longer than the breadth of the raerus ; dactylus slightly curved and 

 acute. Second and third segments of the abdomen with the inferior 

 portion of the posterior margin sinuous, and the inferior angle 

 prominent, but scarcely less than right-angled. The outer rami in 

 all the caudal stylets slightly shorter than the inner, and all the rami 

 armed with short spines above and more slender spines at the tips. 

 Telson stout, about as broad as long and scarcely more than half as 

 long as the peduncle of the posterior caudal stylets, the posterior 

 margin with a few setiform hairs each side. 



In the female the hands in the second pair of limbs are propor- 

 tionally much smaller and more abundantly provided with hairs, 

 while the teeth, or lobes of tha palmary margin, are further apart and
