 of the legs (fig. 7 h) is in several respects different from that of ''/". tciiuispums (fig. 8 a). 



Parasites? "Sacsliaped" structures, like those of preceding specie.s in a similar position were 

 found in a single female from Thor St. 152 and in 29 females from Thor .St. 1S3. 



Occurrence. The Ingolf Expedition has not taken this species, but the vS S. Thor gathered it 

 at a few stations in Denmark Strait and south of Iceland viz:

Distribution etc. As the circuinscriiition of this species is not (juite sure, I feel obliged before 

 discussing its distribution, to write a few words aljout the synonvniw 



The described species differs from vSars' G. brcvispiiins by the S(.)mewhat smaller size, bv the 

 divided rostnnn and \i\ the much longer lateral spines; as Sars does not seem to ha\e realised the 

 importance of the characters found in the laminous process of maxillipeds and in the curious setae of the 

 second basipodite of pes IV, the fact that he does not mention these characters is scarcely of impor- 

 tance. Wolf endc n's description of the female as well as of the male is very incomplete; the females 

 are bigger than my specimens, and the lateral corners seem to be like those of m\- specimens. 

 Farran has (190S p. 32) examined specimens from the west coast of Ireland, which, as far as his few 

 remarks go, show exactly the same differences from Sars' description as my specimens do; really I 

 do not doubt that they belong to the same species. Farran has, however, referred his specimens to 

 Sars' G. affiiiis, and vSars has himself confirmed this identification, though his original specimens of 

 G. affinis only measured 3'6 mm. vSars' description is too incomplete to be of much value. Though 

 Sars regards G. brcvispiiins as well as afjinis from the Monaco Expedition as different species, it is 

 most probable that the animals which are recorded from the Fceroe channel and the north-east 

 Atlantic under the name of G. ///ii/or, aftiiiis and brcvispiiins ought to be referred to the same species, 

 varying in size from 3-6 to 4-65 mm. If this species is not identical with G. brcvispiiins its name ought 

 to be 6". iiiajur Wolf. This species or variety is distributed as far north as Denmark Strait and 

 the Fteroe-Iceland channel, and is found as far sontli at least as 50° L. N.; G. brcvispiiins \no\)'jv 

 which, as seen abo\-e, differs from the southern form by the larger size and shorter lateral sjiines, has been 

 taken in the western part of the polar basin cro.ssed by Nans en (at 84'' L. N. rather plentifully), once 

 in the sea between Finmarken and Jan Mayen, but rather curiously not in any of tlie numerous 

 samples brought home by the Due d'Orlean.s. 



From G. iiitc'nncJins Wolf, it differs by the less i)ointed lamina of the basipodite of the 

 maxillij^eds.
