The species is somewhat variable, but I find no sufficient reason to divide the forms belonging 
hither into two species, as has been done by Sars, even if I have to acknowledge that most of the 
found and examined specimens tolerably well or decidedly can be said to belong either to the /. 
spinosum of Sars, or to his W. Aørtipes, as these species are diagnosticated and described in his last, 
large, and excellent work. Perhaps I may also here be permitted to state my opinion that Sars may 
be said generally to be too much inclined to form new and many species and genera inside the Ar- 
thropoda, whether it be Crustacea or Pycnogonida, which for the rest have been studied and drawn 
by him in so excellent a manner. That such a different view of the species and the genus cannot 
be referred to a less successful representation in words or in figures, and that the dispute cannot be 
- decided by «original specimens», will already be shown by the circumstance, that our museum by the 
liberality of Professor Sars is possessed of several such critical specimens, that have been determined 
by him, and that nevertheless my uncertainty and doubt of the goodness of the species have not 
been removed.

This great number of stations shows it to be a widely spread species, mostly, however, to the south, 
in the southern part of the Norwegian Sea, and the northern part of the Atlantic, and into the Den- 
mark Strait to 66? 18' Lat. N.; also, however, in the Greenland Sea, a little north of Iceland, and in 
the Davis Strait to 65”? 57' Lat. N. 55” 30' Long. W. The depths were mostly from ca. 300 to ca. 800 
fath., im a few instances between ca. 70 and ca. 140 fath., and rarely the water was so low as 35 
and 44 fath. 
From the collections of the Zoological Museum the following stations may furthermore be 
added: the Davis Strait, 66”? 49' Lat. N. 66” 28' Long. W., 285 fath. (Wandel); 66? 32' Lat. N. 55” 34' Long. W.
