out like a finger. Hooks of segments 1 to 3 are not robust, and lack bristles, are more 

 or less changed, and usually stand singly in each foot ; neck of fully developed hook is 

 constricted internally, and the gular bristles join under the main fang. Anterior bristles 

 with narrow or vanishing wings and a distinct series of spikes. Posterior bristles 

 have narrow wings and smooth points. Tubes free, straight or rather thin.

Specific characters. — Anterior cephalic process rather short ; cephalic rim low, with 

 faintly indicated lateral notches ; posterior notch also faint. Ocelli numerous, in front of 

 mouth. Feet of the seventh setigerous segment somewhat in front of the posterior third. 

 Mneteen setigerous and three posterior achaatous segments. Three pairs of long, anal 

 cirri, besides the ventral ; the short cirri — to the number of 1 to 4 — occur in each 

 interval. Glandular bands in first seven setigerous segments, and on the fourth the 

 band occupies half the section behind the feet ; posterior part of the seventh setigerous 

 segment is completely though sparsely covered with glands dorsally ; the second has 

 scattered glands, chiefly in front of feet; the third is similarly and generally covered. 

 The eighth has a distinct glandular band between the middle and the feet. From the 

 middle of the seventh setigerous segment the glandular bands follow the ventral nerve- 

 cord, and are strongly marked from the ninth to the fourteenth segments. More or less 

 faint, longitudinal, glandular bands occur to the front and rear of the uppermost hooks, 

 in the direction of the neighbouring bristles, from the eighth to the twelfth or thirteenth 

 bristled segments inclusive. Hooks of the first three segments have a rather long inner 

 section and three or four teeth ; those fully developed behind have six teeth as a 

 maximum. The bristles are specially numerous on the eighth and ninth setigerous 

 segments, and in many of the middle and posterior segments the commencement of the 

 tip is more or less distinctly enlarged. Nephridia in setigerous segments 7 to 9. 

 Cunningham and Ramage state that the colour is pinkish, pale towards the anterior end, 

 with broad bands of deep red surrounding the body at intervals. Tubes rather thin and 

 brittle, of membrane and fine grains of sand— chiefly light in colour.

Habitat. — ? Firth of Forth, in great numbers, 200 or 300 yards to the west of the 

 Birnie Rocks (Cunningham and Ramage) ; Blacksod Bay, Galway Bay, and other Irish, 

 localities (Arwidsson). In the Forth a change seems to have taken place in the locality 

 (Birnie) since 1887, as no specimen could now be obtained. Liverpool Bay (Hornell) ?
