REPOKT ON THE ANNELIDA.

inferior lamella (the homologue of the ventral cirrus) is convex along its inferior margin, 
and its tip projects considerably beyond the setigerous region. At the thirtieth foot 
(PL XXXII. fig. 8) the ventral lamella is more acute. At the fiftieth foot the superior 
lamella is less pointed, the blunt tip being carried downward, and the outward curve 
along the inferior border being much more decidedly produced. The inferior lamella is 
more acutely pointed, but it does not project so far beyond the setigerous region as in 
front. At the ninety-second foot, again, the superior lamella becomes more regularly 
lanceolate, though broader than in front, and there is also a slight increase in the breadth 
of the inferior lamella, which, however, remains pointed. 
The extruded proboscis shows six rows of papillae on each side basally, the number in 
each line being about twelve. The distal region is roughly marked transversely with six 
rows of warts. The intestinal canal is empty. 
The example is distended with ova posteriorly. This species approaches most nearly 
to the Phyllodoce {Anaitis) madeirensis of Langerhans,^ but the terminal process of the 
bristles is decidedly longer. 
Phyllodoce duplex, n. sp. (PI, XXVII. fig. 8 ; PL XXXII. fig. 9 ; PL XVa. fig, 1). 
Habitat. — Trawled in 150 fathoms off Twofold Bay, near Station 163, April 4, 
1874; lat. 36° 59' S., long, 150° 20' E.; surface temperature, 71°‘0; sea-bed, green 
mud. 
The specimen is much coiled, but its length appears to be upwards of 40 mm., and its 
breadth at the widest part (anteriorly) about 3 mm. 
It approaches the foregoing [Phyllodoce sanctce vincentis) very closely both in 
external appearance and in certain structural features. The dorsum has a brownish hue 
throughout, darker in front, pale posteriorly, the tints being due to bars of pigment 
(narrow in front, wider posteriorly) at the junctions of the segments. 
The head is somewhat broader than in the previous form, and more deeply cordate at 
the posterior border. The eyes are about the same size (proportionally), and likewise 
show a trace of a “ lens.” The other processes are similar. The exserted proboscis has 
basall}^, in front of the snout, a single median line of about five papillae. In the usual 
position, again, on each side, there are six rows, of about eight or nine papillae in each. 
The distal region presents no peculiarity, having six rugae, with the usual warts at the 
tip, and a series of papillae around the aperture. 
A general glance over the feet shows that the chief difference between this anc. the 
former is the somewhat larger size of the superior lamellae. The tenth foot resembles
