At tlie sami' station. (There is no information as to depth, etc.) 

 / April: 1. IV. 



H. H. Gkan writes as follows about this species, 1902, p. 67: ,,. . . aber die geschlechts- 

 reifeu Maunchen schwiirmen umher ini freien Wasser, wo sie an Norwegens Kiisten besonders 

 iiu Winter und Friihling in groBer Menge ganz an der Oberfiache angetroffen werden konnen." 



These facts show that this species, like the preceding one, is as a rule very rarely found 

 ill plankton (it is to be mentioned that it is also rather rare in the bottom samples, much more 

 uncommon than Ph. (Ph.) globosa) though it certainly exists there in rather great numbers, 

 and that it is found planktonically at all times of the year. 



Ph. (Ph.) interpuncta: 



G. S. Brady writes 1868 b, }:». 464 that this species was ,, taken abimdantly in 

 the to wing-net." 



In the plankton tables of the ..C o n s e i 1 p e r m a n e n t " this species is only 

 mentioned once:* 



1906: 



November: Sc. 32, lat. 58^08' N., long. 2" 00' W'.; depth to the bottom 80 ju. 

 10 m. rr. 



Ph. (Ph.) Macandrei: 



This species was also caught in the plankton only on one occasion by the ,,C o n s e i 1 

 p e r m a n e n t": 



1905: 



August: Sc. 5 A., hit. 60" 05' X., long. 0» 48' W.; depth to the bottom, 111 m.' 

 (.» m. +. 



Besides Philumedes (Ph.) globosa two of the species of this genus that I have had an 

 opportunity of investigating, Ph. (Ph.) rotunda and Ph. ( Sderoconcha) Appellofi, were characterized 

 by always having the long natatory bristles of the second antenna of the females with eggs 

 in the brood chamber broken in the same way as is described above for the first-mentioned 

 species. 



In the case of Ph. (Ph.) Lilljehorgi, among the specimens investigated by me, some 

 females — both from Lofoten and from Skager Rak — with eggs in the brood chamber had 

 long, unbroken natatory bristles on the second antenna; most females of this kind were, however, 

 characterized by having these bristles broken in the same way as in the three preceding species. 



Ph. (Ph.) Eugeniae, on the other hand, always had long, unbroken natatory bristles 

 on the second antenna in the females with eggs in the brood chamber which I have examined. 



One other species of this genus, which is not included in tliis treatise, namely Ph. (Sdero- 

 concha) Folini, was investigated by me with regard to this cliaracter. In the description that 

 (i. O. Sars, 1887, pp. 52 and 53, gives of the second antenna in the female of this species we 

 read the following statement: ,,2det Par Antenner hos Hunnen vistM- vistnok idethele samme
