426 PRAGERIA REMOTA. 
PR&GERIA REMOTA, Southern, 1914. Plate CXXXVIII, fig. 1—animal enlarged; Plate 
XXXIV, figs. 3, 34 and 3b—bristles. 
Specific Characters.—Head fused with the anterior segments; brain with elongate 
lobes united in front and stretching into the fourth bristled segment. Behind the middle 
are two pairs of black eyes resting on the brain, the pair on each side being connate, the 
lenses pointing in opposite directions ; two additional pigment-specks behind the middle of 
the bram. In front of the brain is a flattened four-sided lobe, probably representing the head, 
and surrounded on its anterior sides by the enlarged bases of the buccal feet, which are fused 
with the front of the head—except for a dorsal and a ventral groove. Each contains a large 
spine, swollen in the middle and dilated at the tip, where it 1s bevelled and may have a few 
spikes, and its imner end is near the base of the first bristled foot. The massive base ends 
dorsally in a tapering cirrus, and beneath it is a small flask-shaped cirrus. To the ventral 
surface of the buccal feet are attached a pair of long, slender cirri about three times as long 
as the dorsal buccal cirri, the bases of which are enclosed by conspicuous membranous sheath 
(homologues of the buccal cirri of the Polynoidee, Ehlers, whereas Southern considers them 
homologous with the palps of the Polynoide). Mouth a transverse slit on the ventral surface, 
guarded behind by a crenulate lower lip. Body long and narrow (7--15 mm.), tapering a 
little toward the head, and more distinctly posteriorly ; segments fifty-five or more. Colour- 
less or flesh-coloured ; those in the middle of the body almost as long as broad, with elongate 
feet. Anal segment button-shaped, with two long slender anal cirri. Proboscis eversible, 
with fourteen conical amber-coloured papille, the two lateral carrying in addition a small 
papilla on the outer margin. Hach jaw is crescent-shaped, with irregular projections. It is 
followed by a muscular stomach occupying three to four segments. First setigerous foot 
with a slender and elongate ventral cirrus as mm Pesione; dorsal cirrus of the second foot 
normal, that of Pesione being long and slender. ‘The feet (e.g., the fifth) have an elongate 
bifid setigerous lobe ; dorsal and ventral cirri spherical, attached by narrow bases and with 
terminal papille carrying palpocils; two spines with curved tips, the upper representing 
the reduced dorsal division, besides four compound bristles and one simple. The compound 
have slightly curved shatts, bifid at the tip, the terminal piece pointed with a row of fine 
teeth. The dorsal bristle is thick, expanded and bevelled at the tip, which has a row of 
spines. About the tenth or twelfth foot a second simple bristle occurs beneath the dorsal, 
and it has a smooth tip. Genital papille absent. Immature ova found in May.

Habitat—Dredged in Dingle Bay, in 10 to 20 fathoms, on a bottom of sand and shells 
or gravel; those from Clew Bay were captured in a fine-meshed tow-net attached to the 
dredge in 24 to 27 fathoms (Southern). 
Nothing can be added to the excellent description and figures of Southern. The stout 
simple dorsal bristle has a characteristic spur or heel, besides the spmous edge. Moreover, 
this spur is apparently homologous with the articular process at the end of the shaft of the
