312 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [606] 
Off Block Island, 29 fathoms; off Buzzard’s Bay, 25 fathoms, mud. 
Great Egg Harbor (Leidy). 
BRADA SETOSA Verrill, sp. nov. (p. 508.) 
Body short, oblong, sub-cylindrical, flattened below, tapering a little 
toward both ends, which are obtuse; composed of seventeen setigerous 
segments. Skin covered with small, prominent, acute papillae. Upper 
fascicles of setze long, slender, light colored; lower fascicles larger, com- 
posed of stouter, long, dark colored sets, surrounded at base by small 
cirriform appendages. Ventral cirrus small. 
Length of preserved specimen, 10™™; diameter, 2.5™™. 
Off Gay Head, 8 to 10 fathoms, among muscles, &e. 
STERNASPIS FOSSOR Stimpson, Plate XLV, fig. 74. (p. 507.) 
Marine Invertebrata of Grand Manan, p. 29, fig. 19, 1853. 
Off Gay Head, 19 fathoms, soft mud; common in the Bay of Fundy 
in 10 to 90 fathoms, mud; near Saint George’s Bank, 110 fathoms, 
sandy mud; Casco Bay, 20 fathoms. 
CIRRATULUS GRANDIS Verrill, sp. nov. Plate XV, figs. 80,81. (p. 319). 
Body large and stout, anteriorly subeylindrical, somewhat flattened 
and tapering slightly posteriorly, and rather abrupt! y tapered anteriorly. 
Head small, acute, with obscure brownish spots above, but apparently 
without distinct ocelli. Posterior end obtuse, the orifice surrounded by 
a thickened, slightly crenulated border. Posterior to the mouth there 
are about seven rather indistinct annuli (perhaps four biannulated 
segments) destitute of appendages; the two next segments bear two 
fascicles of small seta on each side, and two crowded dorsal clusters of 
long slender branchial cirri; these clusters nearly meet on the dorsal 
line, leaving only a narrow naked space, and contain a large number of 
cirri, usually of various lengths, closely crowded together. Farther 
back the “ feet” consist of small and slightly prominent upper and lower 
rami, connected by aslightly raised, transverse ridge ; each ramus bears 
a small fascicle of short, slender, acute scte, in a transverse row ; and 
a few stouter curved spinules, which project but little from the surface ; 
posteriorly the spinules are more numerous and the slender sete fewer 
and a little longer, but they are scarcely equal to one-tenth of the diam- 
eter of the body. Along nearly the whole length of the body long 
slender branchial cirri arise from above most of the upper rami, but 
many of these are generally broken off in preserved specimens. In 
alcohol the lower surface of the body is generally flat or concave; the 
‘“‘ feet” occupy an elevated lateral ridge, often separated from both the 
ventral and dorsal surface by a deep groove; and the dorsal surface is 
moderately convex. The annulations are short, very numerous, and 
distinct. Color, when living, dull yellow, yellowish green, yellowish 
orange, greenish orange to orange-brown, darkest anteriorly, and often
