sinus above. Eyes small, rounded. Antenna 1 elongate, 2"^ Joint longer 

 than 1^*, nearly thrice as long as 3^; flagellum nearly as long as peduncle, 

 in d attainiug 23 joints; accessory flagellum with 5 joints, the last minute. 

 Antenna 2 in d and § not distinguishable from those in ü. petalocera 

 (p. 681); flagellum in d attaining 16 joints. Gnathopod 1, 2*^ Joint veiy 

 broad except at the base, 5*^ Joint short, broad, produced to a prominent 

 tooth with irregulär apex, 6^^ very broad. especially in ö, with basal process 

 projecting beyond process of 5^^ Joint, its blunt apex cariying a stout spine; 

 the long oblique palm minutely crenulate throughout, with a very slight 

 cavity at each end; finger reachiug basal process of 6^^^ Joint, teeth of inner 

 margin not very conspicuous, setae of outer numerous and strong. Gnatho- 

 pod 2, 5*^ Joint decidedly longer than 6**^, both very setose, 6*'* narrowly 

 oval or almost tapering, palm almost obsolete; finger very small. Peraeo- 

 pods 1 — 5 slender; 2"^ Joint very little expanded, rather more so in peraeo- 

 pods 1 and 2 than in 3 — 5, setose in the latter. Uropods 1 and 2 not 

 elongate, spines few but stout, especially the apical ones; rami nearly equal 

 to one another, more than half as long as peduncle. üropod 3, inner 

 process of peduncle not very broad, with an oblique line distinctly defining 

 it as representing the inner raraus, tipped with 2 or 3 setae; outer ramus 

 longer than inner and produced beyond it, fringed with 7 setae. Telson 

 rounded. Colour red or brown, mottled with white: antennae 1 and 2 annulated 

 and gnathopod 1 marked with bright red (Smith). L. reaching 15 mm.

9 unknown. — ö. Head, rostram rather long; front corners truncate, 

 rather prominent. Side-plate 1 acute in front. Pleon segment 3, postero- 

 lateral corners with a rather small acute but not produced point, without 

 conspicuous sinus between it and the bulging bind margin. Eyes perhaps 

 wanting. Antenna 1, 2^ Joint thrice as long as 3'^; accessory flagellum (in 

 figure) 4- or 5-jointed. Antenna 2, antepenultimate and penultimate joints 

 of peduncle scarcely so stout as in ü. leucopis, somewhat compressed. Gnatho- 

 pods 1 and 2 seemingly as in ü. leucopis. üropod 1, peduncle about 

 ^3 longer than the rami, which have stout spines. Üropod 3, inner process 

 of peduncle. though not separated from the base by an articulating membrane, 

 indicating a small inner ramus, tipped with 2 spinules; outer ramus broader 

 and much longer than inner and reaching beyond it, with a spinule and 

 some setae. Telson shortly oval. L. nearly 9 mm.
