preceding joints armed on their inner edges witii plumose setae, tlie merus liaving, 

 in addition, ordinary setae, tlie carpus armed witli a few simple setae, tlie propo- 

 dus similarly armed to the carpus. Second thoracic legs relatively shorter tlian 

 in the type species, with the merus slightly loiiger than the carpus, propodus very 

 smail, nail distinct and longer than the propodus; latter armed with about five 

 plumose setae at its tip in addition to a few simple setae, not nearly so densely 

 armed as in the type species; remaining joints feebly armed witii simple setae 

 only. Endopods of the remaining thoracic limbs missing in the type specimens. 

 Exopods of the thoracic limbs well developed, those of the first and second limbs 

 longer than the endopods, outer distal corner of the basal Joint slightly acuminate, 

 flagelliform part of ten joints. Pleopods of the female as usual for the gemis, 

 those of the male well developed, natatory, inner brauch of the first pair a short 

 ronuded lobe armed at the tip with three setae and with three setae near its base, 

 lateral lobe rather narrow with two setae at its tip; second, third, aud fifth pleo- 

 pods of the male consisting of two equal nuiltiarticulate branches, the inner brauch 

 with the usual lateral lobe; fourtli pair of pleopods of exactiy the same strncture 

 as the otiiers but with the outer brauch termiuating in a very long strong seta, 

 quite simple and longer than the whole pleopod itself. Telson as long as the 

 last Segment of the pleon, lateral margins straight, whole telson gradually narrowiug 

 to its apex, latter broadly rounded, entire, armed with three (? sometimes four) 

 pairs of equal spiues, which are about one-fifth of the leugth of the telson, and 

 are adorueii on each side with a closely set row of minute spinules or setae; 

 median setae abseut; lateral margins armed with about thirteeu short spines 

 occupying the distal two-thirds of the margin. Inner uropods about one and a 

 quarter times as long as the telson, ciliate all rouuii, witii a singie spine at the 

 inner posterior corner of the otocyst. Outer uropods about oue and a third times 

 as long as the inner and broader than the latter. Leugth, 10 mm."" (Holt u. Tattersall,
