KULALIA PUSILLA. 431 
Fauvel (1911) considers that this species may be identical with Hteone spetsbergensis, 
Malmgren, but, as indicated in the foregoing remarks, there are reasons for keeping them 
separate. 
Southern! considers that Hteone spetsberyensis and E. pusilla are identical, and that 
De Quatrefages” species, HL. foliosa, is the same form, and he adopts the latter title. What- 
ever the ultimate view may be, the bristles of Southern’s H. foliosa (Plate XXXYV, fig. 19) 
are identical with those of EH. spetsbergensis, Malmgren, whose title has as much reason to 
be retained as that of De Quatrefages, more especially as his figures and description are 
readily followed: 
KULALIA PUSILLA, Mrsted, 1843. Plate CX XXIV, fig. 8—bristle. 
Specific Characters.—Head conical, rounded in front ; eyes situated posteriorly ; median 
tentacle small; first pair of tentacular cirri on the buccal segment ; the second and third 
pairs occur on the second segment, and the superior is the longer, whilst below is a rudiment 
of a foot with a bristle-tuft The third segment has the fourth pair of tentacular cirri as 
long as the preceding, a bristle-tuft and a ventral cirrus. Body 8 lines long, greyish-green 
or brownish, with brown or green cirri, with a green dorsal stripe in the middle line, whilst 
ventrally two brownish points occur at the exterior of each segment; segments thirty to 
eighty ; small ovoid dorsal cirri on the fourth segment ; all the dorsal cirri easily detached, 
and they do not overlap. The anal cirri resemble the dorsal. Proboscis covered with minute 
papille, and with a circle of twenty-four comparatively large blunt papilla. Bristles with 
three minute spines on the end of the shaft, and the terminal piece is serrated.

Habitat—tIn Laminarian roots between tide-marks, and dredged also in 1 fathom in 
Blacksod Bay, Ballynakill Harbour in 2—4 fathoms, Loch Swilly (Southern). 
North Sea (irsted) ; Sweden (Loven); Dinard, France (De St. Joseph). 
This minute species has probably been overlooked in the collections of British observers 
until Southern’s careful investigations showed that it is not uncommon on the West Coast 
of Ireland, whilst De St. Joseph dredged it frequently at Dinard. The dorsal cirrus is 
elongate-ovoid, and the two anal cirri are similar. The setigerous process bears a fascicle 
of slightly curved, short bristles with enlarged ends of the shafts and tapered terminal pieces 
with serrations (Plate CX XXIV, fig. 8). A female bore ova of considerable size in July.
