Habitat. — Off East Sands, St. Andrews, small; Plymouth (Spence Bate and B. 

 Howe) ; Bressay Sound, 7 fathoms, medium ; St. Magnus Bay, 78 — 83 and 100 fathoms ; 

 off the Hebrides (Minch), large (J. G. Jeffreys) ; off the coast of Durham, large (Prof. 

 G. S. Brady) ; coast of Kerry, large (A. G. Moore) ; Berehaven, Ireland (R. I. A., 1885), 

 medium and good examples of tubes; 45 fathoms, S.W. Ireland; 48 fathoms, mouth of 

 Kenmore River, small; log. 21 (A. C. Haddon, 1885); log. 22, S.W. Ireland (R. I. A., 

 1885), 40 fathoms, north of Bantry Bay; stat, 34 (S. F. B.), small; off St. Peter Port, 

 Guernsey, tube large; Lochmaddy, North Uist, small (W. C. M.) ; Dublin Bay, Blacksod 

 and Clew Bays (Southern) ; "Porcupine," 1869, 173 and 422 fathoms, tubes of sponge 

 spicules; 15 — 20 fathoms off Peel, Isle of Man, small, in greyish mud. 



Abroad it extends to the shores of Norway, Sweden and Finmark, as well as to the 

 North Sea (Pathke, Ehlers, etc.) ; Mediterranean and Adriatic (Grube, Panceri, Verany, 

 Marion, Stossich, Claparede, etc.). Claparede says it is comparatively rare at Naples; 

 Newfoundland (Fauvel) ; American shores (Leicly). 



The crown in this species bears from eleven to thirteen paleolse, which in well- 

 preserved examples are so brittle that few can be removed entire. They are flattened golden 

 bristles which are a little narrowed at the base, remain of uniform diameter for some 

 distance and then taper to a fine point, which is either slightly curved or boldly bent round 

 like a hook (Plate CXXIV, fig. 2), thus differing, for instance, from those of Lagis Koreni, 

 which are coiled after the manner of a watch-spring. The dorsal collar at the margin of 

 the flattened scabrous area above the paleolee is cut into rather long fimbriae with a broad 

 base and a tapered tip, the latter, however, not being acute, and the collar runs ventro- 

 laterally almost to the base of the anterior cirrus or tentacle, after the manner of Lagis 

 Koreni. The cirrus is of average length and is tapered from base to apex. From its base 

 a ridge passes obliquely backward and inward on each side to the mouth. The great 

 length of the rim of the dorsal scabrous plate circumscribes the area of the veil, which is
