with long, stifE secondary bristles at the middle, distally they have short hairs or are bare; 

 this endite has one medial bristle, of about the same type and size as that of the preceding endite. 

 The second exopodite joint is slightly shorter than that of the preceding species. It has a rather 

 large number of bristles, all situated very near the ventral edge of the joint. The two (sometimes 

 the three) posterior of these bristles are rather long, with long, soft hairs right to the point. 

 There is no pronounced gap between these bristles and the others. Ten to seventeen of the 

 remaining bristles are of moderate and somewhat varying lengths, with long hairs at the 

 middle and short hairs distally; their long hairs are not arranged in distinct wreaths, those 

 on the posterior of these bristles are rather soft, those on the anterior ones are more stiff, 

 even somewhat stifier than in the preceding species. From six to twelve bristles have short 

 hairs, are, as a rule, not inconsiderably shorter than the other bristles on this joint and are 

 somewhat, though only slightly, displaced from the ventral edge of the joint up the lateral 

 side. The pilosity is similar to that of the preceding species. 



Seventh limb: — This is very similar to that of the preceding species. The 

 following differences are to be noted: Distally there are from eleven to thirteen ventral cleaning 

 bristles and nine or ten (usually nine) dorsal ones placed very close together. Scattered irre- 

 gularly proximaUy of these there are eleven or twelve ventral and from ten to fourteen dorsal 

 cleaning bristles. The cleaning bristles are equipped with from three to seven bells. The end 

 comb consists of from ten to thirteen distal teeth and five or six proximal teeth on both sides 

 of these. The distal wart on the dorsal chitinous plate of the distal cavity is of about the 

 same type as in the preceding species, its central tooth, however, seems always to have a 

 single point. In other respects this limb is similar to that of the preceding species. 



F u r c a : — This is very like that of the preceding species, with the same number 

 of claws, aU well defined from the lamellae. The fourth claw is usually somewhat short and 

 weak comparatively, sometimes its weakness is even rather striking. The curvature of the
