PANTOPODA FROM PRAJSZ-JOSEP LAND. 627 



Family PALLENiDiE. 



PSKUDOPALLENE SPINIPES (Fah.). 



E. 10. 77° 55' N. lat., 53° E. long. ; 180 fms. July 1897. 

 1 immature female. 



E. 31. Off Cape Mary Harmsworth ; 53-93 fms. 1 August, 

 1897. 1 immature male. 



These specimens are both about 3 mm. in length and 20 mm. 

 in expanse of legs; according to Sars (4) adults are 4^ mm. 

 long and 39 mm. in expause. The female specimen (E. 10) has 

 only five segments in the false leg. In the male (E. 31) the full 

 number of segments (ten) are present, but these limbs are 

 barely as long as the body. In the general form of the body, 

 the legs and their armature, both specimens agree closely with 

 Sars's description and figures. 



The discovery of this pycnogon near Eranz-Josef Land con- 

 siderably extends our knowledge of its geographical and bathy- 

 metric range. According to Sars it is a scarce shallow-water 

 species (20 fms.) on the coast of Norway, and it has been found 

 also on the coasts of Grreenland, Northern Kussia, and in tlie 

 Kara Sea. 



Family Ntmphonid^. 

 Nymphon brevitarse, Krdyer. 



E. 1. Off Flora Cottage, 1 mile; 15 fms. 10 Sept. 1896. 

 1 male. 



E. 8. f mile S.W. of Elmwood ; 20 fms. 20 June, 1897. 

 1 male ; 1 immature specimen. 



These pyeuogons agree closely with Sars's descriptions and 

 figures of this species, which seems to be scarce, though of wide 

 distribution, having been found off the coast of Greenland and 

 in the Strait of Matotschkin Sharr. It appears to be a shallow- 

 water form. I am quite inclined to agree with Sars that it is 

 worthy of specific distinction from N. grossipes, if only on 

 account of the different denticulation on the spines of the false 

 legs. It is probable that the pycnogon from Franz-Josef Land, 

 recorded by Miers (2) as N. gracile, is referable to this form, as 

 the species which Sars identifies as the true N. gracile of Leach 

 is apparently unknown in the Arctic regions.
