REPORT ON THE ANNELIDA.

tliree on each side, or three on one and two on the other. The teeth are comparatively 
large, and stand prominently ont from the stem. The shaft has numerous minute nodules 
on its surface (PI. IVa. fig. 13, representing a portion a short distance below the inferior 
end of PI. Va. fig. 10), and they are always seen on the side corresponding with the 
concavity at the tip. 
The ventral bristles (PI. Va. fig. 9) are quite uniform throughout, and consist 
of an angular and brittle shaft, and a ti]3 with somewhat long pinnae. No spur was 
observed, and no trace of such ever having been present. There is no enlargement at 
the bases of the pinnae, and the latter at the tip are only a little more slender than those 
further down. 
The ventral surface is smooth to the naked eye, but when examined microscopically 
shows a few somewhat clavate papillae, larger than in var. ivillemoesi and the rest, and the 
cirri and other parts are similar to those in its allies. The dorsal felt is somewhat friable 
and soft, and presents the usual elongated hairs enveloped in gelatinous material loaded 
with sand-grains. The intestinal canal contained fragments of an Amphipod. 
Prof. Grube describes ^ a species [Lcetmonice violascens) from the China Sea having a 
dorsal coat of felt, purplish scales, and dorsal spines with four recurved fangs. The 
description, however, is not sufficiently minute to render identification possible. 
Lmtmonice aphroditoides, n. sp. (PI. YII. figs. 4, 5 ; PL Va. figs. 11-15). 
Trawled at Station 235 (somewhat to the south of Yedo, Japan), June 4, 1875 ; lat. 
34° 7' N., long. 138° 0' E.; depth, 565 fathoms ; bottom temperature 38°‘l, surface 73°‘0 ; 
green mud. 
The length of the single example is 25 mm., and its greatest breadth (exclusive of 
bristles) is about 16 mm. 
The outline of the body is rather broadly ovoid, and the posterior end is peculiarly 
attenuated, and since there is no trace of reproduction having occurred this would seem to 
be normal. The number of segments is thirty -nine. To the naked eye the dorsal cover- 
ing (which entirely conceals the scales) appears to be composed of mucilaginous substance 
and sand. Microscopically, however, this layer is made up of a vast series of fine hairs 
with similar hooked tips to those of Aphrodita, though taking the field as a whole they 
are much more slender. The entire area is covered by a nearly uniform mass of these 
fine fibres, whereas in Aphrodita aculeata, of the same size, there are many fibres of 
much larger diameter amongst the others. The terminal hooks of the fibres in this 
species (PI. Va. fig. 11) do not appear to offer anything diagnostic. The ventral 
surface is covered with numerous minute globular papillae, and the cuticle is so trans- 
parent that the ganglia and nerve-cords are visible in the middle line. The head differs
