shorter than the distal ones; the shorter ones among the former are only about half as long as 

 this joint, the longest among the latter being almost as long as the total length of the first and 

 second endopodite joints. The proximal ones have short hairs or are almost bare, the distal 

 ones have moderately long, stiff secondary bristles. The numerous medial cleaning bristles 

 are moderately long, subcqual, finely pectinated or almost bare, arranged in about eleven or 

 twelve transversal rows. Posteru-distally on this joint there are eight bristles, two of which 

 are situated somewhat distally of the other six; they differ somewhat in length, the longest 

 are somewhat longer than the first endopodite joint; they all have short hairs. (Are the two 

 distal ones of these bristles homologous with the two distal ones in the genus Asteropel) The 

 end joint has five bristles. Three of these are subequal and comparatively powerful and long, 

 about as long as the total length of the first and second endopodite joints, almost bare, with 

 only sparse short hairs. One, situated between the two anterior of three former ones, is 

 only slightly shorter than these, but considerably weaker; it has short hairs. The remaining 

 one, situated behind the others, is of the same type as the last-mentioned one, but somewhat 

 shorter. Pilosity: Basale: On the medial side there are rather abimdant groups of moderately 

 long, stiff hairs. 



Maxilla (fig. 10): — P r o t o p o d i t e: Basale: Dorso-distally, a short distance 

 from the boundary of the endopodite, this joint has a group of three long, powerful, bare bristles 

 differing somewhat in length; the longest is almost twice as long as the endopodite. Proximally, 

 close to these bristles, there is a very short and weak bristle and a short distance proximally 

 of this another similar one. Distally of the three long bristles and on the inside of the joint, 

 along the boundary of the endopodite, there is a series of eight more or less short, weak bristles. 

 Ventero-distally there is a group of three relatively weak bristles on this joint, one of which 

 is about as long as the height of this joint, the two others about half as long (= exopodite?). 

 Endopodite: First joint: Along the anterior side there is a series of four short bristles; 

 the distal one is longest, the others shorter the more proximally they are placed. These bristles, 

 like the short bristles of the basale, are bare or furnished with exceedingly fine, short hairs 

 and end distally in a short, fine hair. Postero-distaUy this joint has a single bristle, which is 

 about as long as the endopodite. The end joint has six rather long bristles differing somewhat 

 in length; the longest is about the same length as the postero-distal bristle of the first endopodite 

 joint. These bristles, like the postero-distal bristle of the first endopodite joint, have short 

 hairs. Pilosity: The basale and the first endopodite joint are furnished on the inside with 

 abundant groups of moderately long, stiff hairs. 



Fifth limb: — Comb (fig. 11): The dorsal edge forms, somewhat in front of the middle, 

 a process that points somewhat forward and is rounded distally. On this process and 

 along the proximal half of the dorsal edge of the comb there is a series of short, 

 finely annulated bristles ending distally in a short, fine hair; seven of these bristles were observed 

 on the right fifth limb, nine on the left. Of the bristles along the ventral edge of the comb those 

 that are situated near the anterior point of the comb are on an average somewhat shorter than 

 the rest. The^remains of the distal ('xojiodite joints are not distinctly defined as a verruca. 

 They have two rather long, subequal bristles, the points of which do not reach the distal
