tlie shorter of the two middle claws, the shortest one only a third or a (juartcr ol' tlie length of 

 the previous one. The powerfid claws of the end joint are bare, the weaker bristles of this 

 joint are often finely pectinated. 



Male: — This differs from that of the female especially by the reduction of the masti- 

 catory parts. It has formerly always been stated in the literature that the coxale is entirely 

 without any endite. (At any rate I have found no statement that this endite exists, unless the 

 following one by G. 0. Sars, 1865. p. 107 can be conceived to refer to this process: ,, Pedum mandi- 

 bularium pars basilaris intus tubercuhj modo minimo pilis 2 brevibus obsito ut rudimento partis 

 incisivae mandibularium instructa." In his work of 1887 G. O. Sars does not mention any difference; 

 with regard to this endite in the males and females of this genus. This statement of G. 0. Sars' 

 is repeated without any alteration by G. S. Brady and A. M. NORMAN in their work of 1896, 

 and it is also found in some other treatises. W. LiLLJEBORG, 1853, G. W. Miller, 1890 and 

 1894 as well as several other writers definitely state that there is no endite on this joint.) On 

 the single male of this genus that I had an opportunity of investigating, the male of Fli. (Ph.) 

 (jlobosa, this process is, however, developed, but it is extremely reduced and probably without 

 anv function (see fig. 13 of the species mentioned). The medial bristles on the proximal half 

 of the second protopodite joint are developed to the same number as in the females, but are 

 very weak. Other bristles too show some, though only a very slight, difference from those 

 (jf the females. 



Maxilla: — This shows strong sexual dimorphism. 



Female: — Protopodite: The basale in rather large and well tlelined from the hrst 

 endopodite joint. The three powerfid endites are always immoveably joined to the protopodite; 

 the third of them is rather pointed distaUy. All the species investigated by me showed a rather 

 close resemblance with regard to the bristles on these processes. (Because of this I have not 

 considered it necessary to reproduce them for more than one species. Ph. (iSc.J AppeUofi; 

 a detailed description of them is given under the hrst species, PJi. (Ph.) (jlobosa.) The first endite 

 in the forms investigated by me has ten to twelve distal bristles, the second has six, the third 

 has nine or ten. Proximally on the outside of the third endite there is a single bristle. Dorso- 

 distally on the coxale there is a single bristle with soft, long hairs. On the boundary between 

 the protopodite and the endopodite there are some bristles: t)ne close to the exopodite, one at 

 about the middle of the inside of the palp and one or more on the anterior edge of the palp. 

 This genus seems to be without any e p i p o d i a 1 a p p e n d a g e. G. W. MULLER writes 

 with regard to this appendage in this genus, 1894, p. 56: ,,bei Philoniedes habe ich an seiner 

 Stelle nur einen flachen, fein behaarten Hautsaum entdecken konnen". In the species investig- 

 ated by me the place at which in the sub-family Ci/pridininae the epipodial appendage issues 

 had also a ,, Hautsaum" with fine, soft hairs situated close together. Exopodite: This is 

 small and short, almost verruciform and naked and situated on the boundary between the 

 |)roto])odite and the endopodite. Endopodite: First joint: Anteriorly near the distal 

 boundary this joint has, in all the forms investigated by me, one l)ristK'. postenorly-distally 

 there are on this joint a somewhat greater number (4 — 5 were observed). These bristles 

 are of moderate lenyth and strength, decreasing; somewhat in length the more anteriorlv^
