 process of 5"' Joint densely setose, produced beyond bind margin of oval 

 6*'^ Joint, wliicli has palm very oblique, longev tban 

 bind margin, not very sharply defined. Gnatbopod 2 



(Fig. 66), process of 5^^' 



Joint very long and slender, 



extending a little beyond 



bind margin of 6*'^ Joint, 



wbicb is more tban 4 times 



as long as broad, palm 



sbort, ratber oblique, well 



defined. Peraeopods 1 — 4 



ratber sbort and stout, 



densely setose, finger ex- 

 treraely small; in peraeopods 1 and 2 6*'> Joint longer tban 5*''. Peraeo- 

 pod 5, 2^ Joint oval, bind margin irregularly curved, 5t'\ 6*^ and 7*^^ joints 

 subequal, eacb longer tban 4*'^ üropod 3, rami narrowly lanceolate, longer 

 tban peduncle, eacb witb about 5 spines. Telson not mucb longer tban broad

Back smootb. Frontal process sbort, deflexed. Side-plate 1 little 

 expanded distally. Eyes oval, occupying almost all tbe frontal process. , 

 Antenna 1 longer tban peduncle of anteuna 2, l*** and 2^^ joints subequal, 

 flagellum sborter tban eitber, o-jointed. Antenna 2, ultimate and penultimate 

 joints of peduncle equal. Gnatbopod 1, process of o*'^ Joint sbort, broad, 6*1' Joint 

 oval, palm very oblique, mucb longer tban tbe obscurely defined bind 

 margin, finger matcbing palm. Gnatbopod' 2, process of 5*'^ Joint ratber 

 long, just reacbing tbe well defined, ratber sbort and oblique palm; tbe 

 6*'i Joint a little widened at tbe palm. Peraeopods 1 and 2, finger described as 

 little, not very weak, for peraeopod 2 figured nearly as long as 6*^ Joint. 

 Peraeopods 3 — 5, finger straigbt, in peraeopod 4 figured as long as ö^'^joint, 

 in peraeopods 3 and 5 longer tban 6*'\ In otber respects agreeing witb
