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 tolerabh- well or decidedh- can be said to belong either to the A'. 

 spii/osiiii/ of Sars, or to his X. Iiirtipcs, 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 vSars 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 sttidied 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 Ijy the 

 liberality of Professor Sars is possessed of several such critical specimens, that have been determined 

 by him, and that nevertheless \\\\ inicertaint\' and doubt of the goodness of the species have not 

 been removed. 



Occurrence. The Ingolf-.stations are: 4, 9, 15, 25, 27, 32, 35, 51, 53, 54, 78, 87, 93, 98, 127, 144. 

 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 mosth- from ca. 300 to ca. 800 

 fath., in 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. 

 100 fath. ( , F\-lla , Holm); 65° 27' Lat. N. 54° 45' Long. AV., 670 fath. (Wandel); 64' 57' Lat N. 55= 14' Long. W., 

 426 fath. (idem); the Denmark Strait, 64' 42' Lat N. 27 43' Long. W., 426 fath. (idem); 65° 39' Lat N. 

 28^ 25' Long. W., 553 fath. ( Fylla , Ryder); the Greenland Sea in Scoresby Sound (Deichmann); the 

 Gaaseland' Bay in the Denmark Island, 5 fath. (Bay); Angmagsahk, 11 fath. (idem); 69- 25' Lat L. 20 i' 

 Long. W., 167 fath. (idem); 71 21' Lat N. 8" 25' Long. W. 160 fath. (Deichmann); 72° 25' Lat N. 19° 33' 

 Long. W. 140 fath. (idem); 72 26' Lat. N. 19 35' Long. W., 105 fath. (idem); 72° 53' Lat N. 20' 36' Long. W., 

 96 fath. (idem). Besides we have it from the Faroe-Shetland Channel 61" 23' Lat N. 5 4' Long. W., 

 255 fath. (Wandel), and from the Skager Rack, the Tromlinger: to X. W. -' ., X. 38 miles, 300 fath. 

 (Joh. Petersen).
