generally 1'nm id in < 'opepoda). Cephalic segment of moderate size and projecting 



ill front to a very small rostral prominence. The- -1 succeeding segments gradually 

 increase in si/e, and are without distinet epimcral plates. I'rosome conside- 

 rably exceeding in length the anterior division, and composed of ^ well-defined 

 gments, the genital se^meni heini: distinctly subdivided in the middle: last se-- 

 inent ahoiit the sj/e of' the preceding one, and having the anal opercle only 

 -lightly indicated. Caudal rami comparatively short and rather broad in their 

 proximal part, hut abruptly contracted distally. the outer edge forming in the 

 middle a nearly rectangular bend, inner edge straight: middle apical seta very 

 long, attaining nearly half the length of the body, and extended straight backwards. 

 Kve inconspicuous. Anterior antenna 1 rather small, scarcely more than half as 

 long as the cephalic segment, and clothed with comparatively short setse, the 4 

 joinK of the proximal part rather thick and of nearly e<|iial length, terminal part 

 narrowing abruptly, with the last joint longer than the other 2 combined. 

 Posterior antennae short and robust, with the distal joint scarcely as long as the 

 proximal one. and armed with 7 claw-like spines, 2 on the outer edge and 5 on 

 the blunted end; outer ramus very small, and tipped with a single spiniform seta. 

 Mandibular palp likewise very small, and provided with only 2 apical setae. 1st 

 pair of legs with the inner ramus somewhat shorter than the outer, distal joint 

 about the length of the proximal one, 'and armed at the tip with a strong claw- 

 like spine and 2 very unequal seta'; terminal joint of outer ramus shorter than 

 either of the 2 preceding joints, and armed at the end with 2 spines and 2 curved 

 setae. The 3 succeeding pairs of essentially the same appearance, inner ramus about 

 the length of the first 2 joints of the outer combined, and provided at the end 

 with a spine and 2 exceedingly long setae, carrying moreover inside near the end 

 a -hurt seta, and in the 3rd pair another similar seta inside the proximal joint : 

 terminal joint of outer rainus in 2nd pair with ). in the 2 succeeding pairs with 

 I', comparatively small seta- inside. Last pair of legs extremely small, with .'! 

 une.|ual setae at the end. and another \ery slender seta attached to a knob-like 

 projection outside.
