adjoining figure are broken); these bristles are of the same type as those on the first joint. Th 

 end joint is rather broad proximally and grows uniformly and gently narrower distally. Along 

 the distal half on the inner side (the dorsal side) it is ,,more or less distinctly cross-furrowed". Its 

 proximal basal bristle is about half as long as the joint or somewhat longer. This bristle is of about 

 uniform thickness, distally rounded; its proximal part is finely annulated, its distal part hyaline. 

 Mandible (figs. 5 — 7): — The proportion between the joints is about as follows:

P ]■ o t o p o d i t e : Basale : Along the dorsal side of the backward pointing process there 

 are about 20 — 30 bristles (the exact number could not be ascertained with certainty because 

 the bristles on the proximal part of the process were defective). Most of these bristles are sub- 

 equal and of moderate length and strength; one of those situated distally is about twice as 

 long as the others and is considerably stronger than these; they are all bare or only rather weakly 

 pectinated. Along the ventral side of this joint there are a rather large number of bristles: At 

 about two thirds of the way along the joint there is a group of three rather long bristles, the 

 longest of which is about as long as the height of this joint. Behind this group there is a series 

 of about seven to ten subequal bristles, which are somewhat weaker than the three former ones 

 and only about as long as half the height of the joint. Of these latter the anterior ones, like 

 the three former ones, have long, stifi secondary bristles at the middle and have short hairs 

 or are almost bare distally; the posterior ones have short hairs. In addition to these bristles 

 there are ventrally a number of more or less short, bare or almost bare bristles; the number 

 of these is not known on account of the defectiveness of the specimen investigated (a number 

 are drawn in the adjoining figure, some are only indicated by marking the places where they 

 are attached). Dorsally this joint has at the middle a series of ten bristles of different lengths, 

 some of them long, about as long as the dorsal side of this joint or even somewhat longer, the 

 shortest only about a fifth or a sixth of this length. The shorter ones of these bristles have 

 short hairs, the long ones have long, stiff secondary bristles at the middle and have exceedingly 

 fine short hairs or are bare distally. This joint has also two dorso-distal bristles of somewhat 

 different lengths; they are of about the same tjrpe as the long dorsal bristles, but somewhat 

 longer. Exopodite: This is about as long as the first endopodite joint. Its two bristles 

 differ somewhat in length, the longest is only about half the length of the exopodite; they are 

 short, have fine hairs or are almost bare. Endopodite: First joint: Ventrally this has a group 

 of three bristles of about the same length and type as the dorso-distal bristles on the 

 second protopodite joint (corresponding to the three similarly placed bristles in the genus 

 Asterofel). Close to and in front of this group there is a row of nine considerably weaker and 

 shorter bristles; these are of different lengths, the longest being about as long as or somewhat 

 longer than this joint, the shortest only about half as long; all these bristles have short hairs 

 except one or a few of the posterior ones, which have long, stiff secondary bristles at the middle. 

 Second joint: On the anterior edge there are exceedingly numerous powerful bristles of different 

 lengths; it is impossible to establish the exact number of these because it is so large and because 

 they are situated so densely. The proximal of these bristles are on the average rather considerably
