not without hesitation that Kröyer 1 ) applied the same name to a 

 species seut to hiui frora the Icelaud coast. We are indebted to 

 him for a good description of the form in which he believed to 

 recognize the species of Fabricius : Hansen 2 ) as well as Gr. Ö. Sars 3 ) 

 rightly , I think , have given the above nanie to the species cor- 

 responding with the description of Kröyer. (G. O. Sars was also 

 able to compare his specimen with the figures published by Kröyer 

 in Gaimard's »Voyage en Scandinavië"), 



This seetns to be a not very common species. Hansen says he 

 has seen the original specimen (only one ?) of Kröyer and he thinks 

 that it was certainly not a full-grown individual. Hansen moreover 

 was able to investigate one single full-grown female specimen only 

 (from the Faroes). G. O. Sars had also one specimen only at his 

 disposition ; it was taken in Saltströmmen, at the mouth of the 

 Salteufjord, at a depth of 80—90 fathoms, among Hydroids. 



No other case of the occurrence of this species has come to 

 my knowledge. Looking through a collection of Pycnogonids 

 belonging to the Helder Zoological Station , I was not a little 

 astonished to recognize the species described by Kröyer, Hansen 

 and G. O. Sars and figured in a masterly way by the last 

 named author , in two specimens of a Nymphon dredged in the North 

 Sea in the summer of 1884 not far from Margate, off the coast 

 of England. I remember perfectly well, that I tried to determine 

 these specimens when I was engaged (in the autumn of 1884) in 

 preparing a short report on the doings of our (then still transpor- 

 table) Zoological Station during the summer of 1884. 1 mentioned the 

 two specimens in the list of the Stations where we had been dredging 

 or trawling during that summer. It was a very remarkable haul, the 

 following description of which is given in the printed report 4 ).
