EULALIA NEBULOSA. 53 



backwards, and probably again diminishes towards the tail, but the posterior region 

 is absent. At the tenth foot the dorsal lamella is ovate with a somewhat blunt tip. The 

 setigerous process is bifid, and the ovate or renif orm ventral lamella extends beyond its tip . 

 The dorsal lamella considerably increases in size at the fortieth foot, but the ventral remains 

 nearly the same. The shafts of the bristles (Plate LXXXIV, fig. 5) are somewhat slender, 

 with a slight curve distally, the enlargement and its spines resembling the parts in Eulalia 

 bilineata. The terminal process begins with a broad base, and rapidly diminishes to a 

 hair-like tip. The edge is finely serrated, and the serrations appear to be continued on the 

 shaft a considerable distance downwards. 



This may be a large example of E. bilineata, and is a male laden with sperms. 



2. Eulalia nebulosa, Montagu, MS. (1808). Plate XLIII, fig. 6 ; Plate LVIII, figs. 1 

 and 2— head; Plate LXVII, figs. 8 and 9— feet ; Plate LXXVII, fig. 1— bristle. 



Head broadly conical, the median tentacle arising a little in front of the eyes, which 

 are large and blackish-brown. Tentacles pale, with a dark speck at the base of the 

 median, one at the base of the anterior pair of tentacular cirri, and another on the enlarged 

 part of the latter pair. Body five to ten inches long, somewhat soft in texture, tapered 

 considerably anteriorly and more evidently so posteriorly, where it terminates in an 

 attenuated tail with the anus at the tip. Only one or two examples — out of dozens — 

 presented two small and somewhat clavate anal cirri. The finely tapered tail is charac- 

 teristic. It is of a dull yellowish or pinkish hue, minutely speckled on the dorsum with 

 dark green touches which are symmetrically arranged — a long lozenge occurring in the 

 middle line in front and a bar behind — stretching between the feet of opposite sides. 

 Montagu figures a row of six spots at the segment-junction, and four on the space behind. 

 Ventral surface pale. Proboscis very long, with a rasp-like series of minute papillaa. 

 Dorsal cirrus large and cordate, the margin dull green, and some have a V-shaped mark 

 in the centre of the process and one or two rows of dark specks above it. The pedicle is 

 large. Setigerous lobe bifid ; bristles pale^ with an enlarged and bevelled tip, while the 

 terminal blade is moderately long, and with a finely serrate edge. The ventral cirrus is 

 o vate-acumm ate .
