From St. loi : 66° 23' N. L., i2°05'W. L., 537 fm., temp. -^ 07°, that is, east of northern Iceland 

 in the cold area, a single specimen is to hand, but as it seems to have been dried, I can say with 

 reasonable certaintv that it has not been taken at the locality, with negative bottom-temperature, from 

 which it is given. 



It seems appropriate with this species to mention all its other localities within the seas mentioned.

 Distribution. This species has been taken at a number of places in the Skager Rak at a 



greater or less distance from the Skaw, in 55 to 275 fm. (material collected by Dr. Joh. Petersen), also 

 at Bohuslan (Goes), in the deep fjords along the whole coast of Norway from Christiania Fjord to 

 Varanger Fjord in depths from 30—60 fm. (M. Sars) to 672 fm. (G. O. Sars) and always in positive 

 bottom-temperatures (2-8°— 67° C), also off the west coast of Norway and north of this between 72° 

 and 73° N. L. (1-5°— 6-9°), further, up towards Spitzbergen at 75° 58' N. L., i3°i8'E.L., 186 fm., temp. 27° 

 (Ohlin); lastly in the most we.sterly part of the Murman Sea, but not near to the White Sea (Birula). 

 In the Bay of Gascony the species has been taken in 425 and 63S fm. (Caullery). Off the east coast 

 of North America it goes from Cape Halifax (ca. 44° N. L.) to ca. 38° 37' N. L. from 94 fm. and down- 

 wards to 524 fm. (S. I. Smith). 



Both G. O. Sars and Ohlin consider it to be "in all probabilit>" of arctic origin. Of this I 

 know nothing, but it is certain that it is not an arctic form. Although it is usually met with in 

 200 — 500 fm., but can go in to 30—60 fm. and down to at least 672 fm., it has never been taken in 

 negative bottom-temperatures; only once it is given from 0°, but the localit}' lies in the Fteroe Channel 

 where an error in the temperature may easih- have arisen on account of the bottom, the temperature 

 being taken at a place with 0° but the animal in reality at some distance at a place with positive 

 temperature. The lowest certain observation among the numerous temperatures is 1-5°, but at most 

 places it measured between 3° and 7°. The occurrence of this species up to almost 76° N. L. and }et 

 living everywhere in positive bottom-temperatures is interesting; with this its occurrence in the Ba)' 

 of Gascony also agrees, the latter further showing sufficiently that the species is not arctic.
