PYCNOGONIDA. 



From the western coast of Greenland it is found from the following localities: Near Upernivik, 18 

 fath. , stones with a few algae (Fylla, Holm); the port of Sukkertoppen , 10 fath. , stones with 

 algse (idem); between the mouth of Kvanefjord and Frederikshaab, 16 fath., (idem); between the rocks 

 and islands outside of Frederikshaab, 10 25 fath. (idem); the straits at Igaussak (south of Frederiks- 

 haab) , 10 fath. (idem) ; from the Davis Strait : 67 4' Lat N. 54 28' Long. W. , 32 fath. , stones without 

 algae (idem); 66 32' Lat. N. 35 34' Long. W., 100 fath. (idem); (mixtuni) 66 1 6' Lat. N. 26 8' Long.W. 

 330 fath., bottom temperature -- i (Wandel); 65 35' Lat. N. 54 50' Long.W., 80 fath. (Fylla, Holm); 

 from the eastern coast of Greenland , in the Greenland Sea : 72 26' Lat N. 19 35' Long. W. 105 fath. 

 (Deichmann); 72 53' Lat. N. 20 36' Long.W., 96 fath. (idem); at Iceland, off Stykkesholm (H. Jonsson); 

 in the Norwegian Sea, 63 15' Lat. N. 9 35' Long.W. 2 70 fath. (Wandel); (mixtum, the original specimen 

 of Kroyer) Trondhjem-Fjord, south of Laxen, 15 fath.; in the channel between the Faroe Islands and 

 the Shetland Islands 61 23' Lat. N. 5 04' Long. W. 225 fath. (Wandel). 



Distribution. Here it is first to be pointed out that I have united N.grossipcs and mix turn, 

 so that the general reference to Sars, Pycnogonidea , 1891, here applies to both the species of Sars. 

 After our conception of the species, N. grossipes should be known as one of the most widely spread 

 Nymfihon-species, from the Kara Sea, the Barents Sea, the seas round Greenland, and the eastern coast 

 of North America towards the north, to the North Sea, nay, even into the Sound, towards the south. 

 Accordingly the Ingolf-expedition has not increased the distributional area of the species.

Hoek says of this species that its oculiferons tubercle is uion valde exaltata apice truncata, 

 I.e. p. 18, which on the following page is rendered by: it is not very elevated and rounded at the 

 apex; but as well Hansen who has examined some 40 specimens, as Sars who has examined a 

 great many, and the present author have only seen specimens with very pointed oculiferous tubercles, 

 so that, no doubt, the single specimen of Hoek has, as is also observed by Hansen, been defective 

 with regard to the oculiferous tubercle; Hoek also says of it that the state of preservation of this 

 specimen was not quite satisfactory , 1. c. p. 19. 



Occurrence. The Ingolf-stations are the following: 105, 116, 138, according to which it has 

 been taken in the Norwegian Sea, from the Faroe Islands in the south in an almost straight line to 

 Jan Mayen in the north; the depths were 371 762 fath. 



Distribution. The species had hitherto only been found as far north as the Kara Sea, the 

 Barents Sea, and midway between the Finmark and Beeren Kiland, at a depth of 20 60 fath., in a 

 single instance of 160 fath., Sars, I.e. p. 75. By the Ingolf it has been taken considerably farther to 

 the south, until 63 22' Lat N., and at somewhat greater depths, until 762 fath.
