ANNELIDA FROM BERMUDA. ras leh 
The lower acicula (Fig. 45) is curved externally, and has two sharp, 
triangular, teeth, of which the lower is very large. 
Body slightly convex above, flattened below; segments numerous, 
short; on the largest specimen, at.the widest part of the body, there 
were four segments, in a length of 1™™. 
Anal cirri lost on all our specimens. Color in alcohol, uniform yellow- 
ish-white. 
Length of longest complete specimen, 60™™. 
Width, 3™™. 
Another specimen, posterior part lost, had a width of 4™™. 
The specific name is given in reference to the denticles on the stem of 
the compound sete. 
EUNICE LONGISETIS 2. sp. 
(Plate X, Figs. 46, 46 a, b-49.) 
Head four-lobed, upper lobes small; antenne smooth, median and 
median lateral reaching back to the fifth segment; lateral about one- 
half as long as the median. 
The dorsal cirri are long and stout (Figs. 46, 46a, b,) on the branchi- 
ated segments, arising just at the base of the branchial stem. 
Ventral cirri stout, reaching beyond the foot. Branchiz begin on the 
sixth setigerous segment, at first as a single filament, delicate, shorter 
than the dorsal cirrus; farther back the number of filaments increases 
to eight, carried on the side of a stout stem, which is nearly double the 
length of the dorsal cirri; on the posterior segments they become re- 
duced to the same condition as on the anterior, but persist to the end. 
The capillary sete are very long, reaching nearly to the end of the 
dorsal cirri (Fig. 47); the compound seté are about one-half as long as 
the capillary, terminal teeth sharp (Fig. 48), nearly at right angles to 
each other. 
In the upper part of the foot are two or three sharp aciculex, project- 
ing slightly; in the lower part, and extending into the ventral cirrus, 
a single, curved, bi-dentate acicula (Fig. 49). 
Body convex above; flattened below; anal segment short; anal cirri 
two, in all respects similar to the dorsal cirri. 
Color (in alcohol), dark reddish-brown. Fourth setigerous segment 
white. Antenne, tentacular cirri, and dorsal cirri evidently banded 
with white and some other color in life, but with only slight traces of 
such marking remaining. Acicule black.
