I), scorpioides is common at West Greenland. Ortmann recorded it from Harden Hay, 20 25 fatli., 

 and Robertson Bay, 5 15 fath.. both places at ab. Lat. 773o' N., and besides from ('.ram-ilk- Hay. ab. I,at. 

 77 N.. 20 30 fath.; Ohlin mentioned it from Murchison Sound, ab. Lat. 77^30' N., 50 fath.; Caiman from 

 Upernivik, Lat. 72^47' N., 13 fath. In 1888 the present author enumerated it from ten localities at or off 

 West Greenland between Lat. 7iio'N., and Lat. 6335'N., depths from 8 10 to 200 fath.; in i8yoProf. Bergendal 

 secured it at two new localities, viz. Jakobshavn, Lat. fxfi$' N., 10 fath., and Kgedesmindc. Lat. oS^' N.; 

 later K. Stephensen recorded it from Nordre Stromfjord. ab. Iat. O74o' N., depths from 4 II and down to 

 27 fath.. and from Bredefjord. ab. Lat. 6o45' N., together with the more southern Skovfjord, deptlis from 

 5 8 and down to 120 153 fath. 



On the northern side of Iceland this species has been taken by "Beskytteren" in Skjalfi'mdi, 21 fath., 

 and by the "Thor" off Husavik, 42 53 fath.; on the east side of Iceland, by Dr. A. C. Johanscn in Hakke 

 Fjord. 20 28 and 52 43 fath., and in Loons Vik, 40 fath. ; by Mag. R. Horring in Faskruds Fjord, 50 20 fath. 



The Ilnd Amdrup Expedition secured it at Jan Mayen, 50 60 and 55 fath., at this island it has 

 been taken by Prof. Nathorst in 7 n and 12 fath. (Ohlin) and in four places at East Greenland between 

 Lat. 693o'N., and Lat. 74i7'N., viz. Cape Dalton, 9 n fath.; Turner Sound, 3 fath.; Hum- Inlet, 10 

 fath. and 7 o fath., finally Cape Borlase Warren, 10 fath. It is on the whole common at northern East Green- 

 land; in 1913 K. Stephensen puts together the statements published by Ohlin, H. J. Hansen and himself; 

 he enumerates ten places between Lat. 7O27' N. and Lat. 76^45' N., and in most of these localities the deptlis 

 were between i and 10 fath., the greatest depth 18 32 fath. 



Distribution. Found at several places in North Norway, going southwards to Salten Fjord, 

 ab. Lat. 67 l ! t N. (G. O. Sars). 1 Furthermore taken at some places on the east side of Spitzbergen, in 7 8
