the four (definitive) distal joints, the d-bristle is somewhat thicker and slightly longer than the 

 e-bristle; proximally they, like the other distal bristles, are rather strongly annulated, distally 

 they are finely and closely annulated, almost hyaUne. The g-bristle is not quite so long as the 

 anterior sides of the second and third joints; it is fm'nished with twenty sensorial filaments. 

 The sensorial filaments on the b-, c-, f- and g-bristles are annulated proximally and almost 

 hyaline distally; they are bare and end distally in a short, fine sensorial hair; on the b-, c- and 

 g-bristles they are situated on the anterior side of the bristle, on the f-bristle on the posterior 

 side, i. e. in the same way as in Asterope. Pilosity: The first joint is almost bare; the second 

 joint has very abundant short, fine hairs on the medial side; otherwise it is bare. 



Second antenna: — The exopodite (fig. 8) is somewhat shorter than the 

 protopodite. The proportion between the joints is about as follows: 



I : II : III : IV : V : VI : VII : VIII : IX = 39 : 7 : 3 : 2 : 2 : 2 : 2 : 2 : 2. 



In other words the first joint is considerably longer than the total length of all the following 

 joints; the second joint is about as long as the two or three following joints. The second to the 

 eighth joints have subequal and powerfvd natatory bristles, which are about as long as the 

 exopodite or somewhat longer and are furnished along their whole length with comparatively 

 long and broad natatory hairs situated very close together but have no spines at all. Distally 

 these bristles are hyaline and end in a short, fine sensorial hair. The ninth joint has four such 

 natatory bristles, of which the three situated ventrally are about as long as the natatory bristles 

 on the preceding joints, the dorsal one is considerably shorter, being about as long as the total 

 length of the eight distal joints. In addition this joint has medially a relatively short bristle which 

 is only as long as the total length of the four or five distal joints; it too is provided along its 

 whole length with long, powerful natatory hairs situated close together. The second to the 

 ninth joints have basal spines; these are comparatively narrow, the one on the eighth joint being 

 the longest, somewhat longer than the end joint; the rest decrease somewhat in length and strength 

 the more proximally they are attached, the one on the second joint being very small and weak; 

 the basal spine of the end joint is somewhat shorter and weaker than that of the eighth joint. 

 The second to the eighth joints have medio-dorsally a mass of long, soft hairs distally; these 

 are about as long as or somewhat longer than the joint^that follows the one to which they are 

 attached (only indicated in the figure). Latero-distally these joints have, in addition, a series 

 of short, fine hairs. The first joint has also some groups of hairs distally. Endopodite: 

 The three joints are all elongated and powerful, the distal one being rather slightly shorter than 

 the second joint (fig. 9). VentraUy on the first joint there are a moderate number of moderatel)' 

 long or rather short bristles, which are finely annulated, rounded distally and end in a short, fine 

 sensorial hair; on the second antenna of the right side there were five such bristles proximally 

 and a series of four along the middle of the joint, on the left antenna the corresponding numbers 

 were six and five (the number was, however, somewhat uncertain, one or more being possibly 

 broken ofi). The second joint has a rather deep furrow ventrally, against which the end joint 

 is folded back. At about two-thii'ds of the way along this joint there is ventrally a group of 

 eleven or twelve moderately long bristles varying somewhat in length (the longest in the
