158 Prof. M‘Intosh’s Notes from the 
(the first) to thirty branches. It differs, however, in that 
the branchize begin on the 3rd foot, whereas in E. violacea 
they are absent on the first five. ‘They lean to the type seen 
in Eunice aphroditois and E. Rousseaut. 
This species also comes near Hunice violaceo-maculata, 
Ehlers, from Tortugas, but the head does not appear to be 
simply bilobate, the branchial filaments are longer and more 
numerous, and the number of teeth on the various plates is 
greater. The bristles, again, are quite different. 
Lumbriconereis fragilis, O. ¥. Miller. 
Great numbers, some of large size, were dredged in 1873 
off Port Hood, Cape Breton; also in Gaspé Bay, 1873; some of 
these were also of large size. In one, the largest, the maxil- 
lary plates only had three teeth, the posterior apparently 
having been abraded, and the edges of the anterior were 
white. The anterior feet had the posterior lobe considerably 
modified, so that in lateral view it had a deep vertical edge 
instead of the more pointed condition in the ordinary forms. 
The black spines are also more numerous. ‘There is, indeed, 
much variation in this respect and in the length of the 
bristles, but it seems unnecessary to do more than to draw 
attention to these differences. 
Lumbriconereis near assimilis, M‘I., but with pale spines. 
A small species was dredged in 200 fathoms south of 
Anticosti in 1871 which had rather prominent feet, with a 
small posterior lobe, the tip of which in the sole example 
projects backward rather abruptly. The spines throughout 
are pale, and the bristles (Pl. XIII. fig. 42) do not offer cause 
for remark. ‘The winged hooks occur on the first segment 
and are continued to the posterior end of the example, which 
is fragmentary. At the 20th foot the tips of the winged 
hooks are long and tapering (Pl. XIII. fig. 43), the crown of 
the hook having minute spines which do not much differ 
from the lowest or chief fang. Posteriorly the winged region 
is shorter and the chief fang of the hook better differentiated 
from the smaller upper spines of the crown. — 
This species comes near the L. robusta of Ehlers *, though 
the spines in the latter are black. 
The dental apparatus of this form had been crushed, and 
all that can be said is that the maxillze had the normal 
outline, the curve being rather flat, and their posterior
