This species was first described by Carlgren, in 1891, from specimens 

 obtained on the west coast of Sweden, from depths of from 40-80 

 fathoms. In 1893 he gave a much more detailed account, and mentions 

 the Gullmars-fjord, " other localities on the Swedish west coast," and 

 the Skagerrak as its distribution. 



Only a few of those obtained by the s.s. Huxley were in a perfect 

 condition, the best being those taken in the Agassiz trawl during short 

 hauls ; those from beam hauls of several hours' duration being frequently 

 almost destitute of tentacles, which would be found adhering to the 

 mesh in all parts of the trawl. 



None of the specimens attained the dimensions of those described 

 by Carlgren, and measurements of fully expanded specimens were not 

 easy owing to the generally great and usually unequal inflation of 

 the body wall. The height of the column varying from 50 to 100 mm. 

 Breadth of oral disk usually equal to the height. Length of inner 

 cycle tentacles up to 80 mm, the outer 25-30 mm. 



Pedal disk thin and not well demarcated. None were attached, but 

 were free in the trawl, and only adhered in a slight degree to any 

 vessel in which they were kept, and as they showed no sign of having 

 been torn from any object it is probable that they lie loosely upon the 

 bottom (sandy). 



Column smooth and polished and thin, finely wrinkled when con- 

 tracted. Tentacles 160, in six cycles in the larger specimens, stout, 

 tapering to the tip, strongly sulcated, fairly contractile, constricted at 

 the base, and very readily thrown off. Disk smooth, two large 

 oesophageal grooves, stomach freely protruded and grooved. 



Some few were of the colours described by Carlgren, " flesh colour 

 all over, tentacles often brown-red on the inner side, gonidial-tubercles 

 and primary mesenteries weak carmine." But the majority had the 

 column chestnut or dull orange (the mesenteries showing as faint white 

 lines during distention) 



Tentacles maroon or, rarely, chestnut, the inner faces much darker 

 than the outer, and the inner cycles darker than the outer. Disk a 

 warm flesh tint, or light orange-brown, with numerous irregular radial 

 lines of dark brown or maroon, of varying widths, but widest and 

 darkest about the base of the tentacles. (Esophageal grooves flesh 

 colour. Throat and stomach brownish pink. The colours persist well
