six short stout spines on its inner margin ; fifth joint with three, sixth j'>iut two, and 

 seventh joint four rather long, strong plumose spines on their inner margins as well 

 as numerous setae. 



Second thomcic //////<* (Fig. 11) with the endopods longer and rather more slender 

 than the first, exopods well developed ; fourth or meral joint produced internally into 

 a large setiferous lamelliform lobe nearly as long as the iiftli joint ; the latter, the 

 longest joint of the limb, longer than the combined length of the sixth and seventh 

 joints, its outer margin armed with a single seta, the distal half of the inner margin 

 slightly excavate with a row of eight short, closely-set plumose spines and a single 

 long plumose seta on the emarginate portion, and a few long simple seta', set widely 

 apart, on the proximal portion of the inner margin ; sixth joint longer than the 

 seventh, its outer margin armed with a few long setae, the proximal portion of the 

 inner margin bearing a row of about nine short closely-set plumose spines and a single 

 long plumose seta, the distal portion of the inner margin with a few long simple seta) ; 

 seventh joint small, armed with numerous long and rather stout simple set;e. 



Third in jiff It thoracic limbs (Fig. 12) with the endopods feeble, long and slender; 

 sixth joint slightly longer and more slender than the fifth ; seventh joint very small, 

 forming with two strong spines a very minute chela, densely clothed with short fine 

 set;e ; the rest of the endopod armed with a few short scattered sct.-r. 



Sixth to I'ii/hlh thoracic //infix (Fig. 13) with the endopods slightly longer and 

 stouter than those of the three preceding pairs ; sixth joint shorter than the fifth ; 

 seventh joint small and bearing a long slightly-curved nail, the junction between the 

 nail and seventh joint being indicated by a seta on the inner margin ; rest of the 

 endopod feebly armed with short setae. 



Exopods of the second to eighth thoracic limbs well-developed ; basal joint long 

 and rather narrow, the outer distal corner rounded : rlagelliforin part composed of from 

 ten to thirteen joints. 



Incubatory lamellse, seven pairs, situated on the second to eighth thoracic limbs. 



Pleopods (Figs. 14 to 18) in the female uniramous, the first pair small, succeeding 

 pairs increasing in size to the fifth pair, which are slightly longer than the sixth 

 segment of the pleon ; first four pairs one-jointed; fifth pair two-jointed, I he second 

 joint longer than the first ; all the pleopods bearing long >((;> at the apex. 



T< l*nn (Fig. 19) rather massive, longer and a little wider than the last segment 

 of the pleon, dorsally grooved, oblong in shape, slightly wider at the apex than at the 

 base, its margins lightly arcuate ; apex truncate or very lightly emarginate, bearing 

 a single median spine with six or seven long spines on either side ; lateral margins 

 armed with from twenty-five to thirty fairly long spines arranged more or less 

 in series. 



Iiunr nrojtotl* broken in both specimens. 



Outer uropud* (Fig. 19) nearly twice as long as the sixth segment of the pleon, 

 two-jointed, the terminal joint about one-seventh as long as the basal ; outer margin
