816 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [610}) 
segments are short and rounded, about as long as broad, much narrowed: 
at each end, and swollen in the middle; next two about twice as long as. 
broad; succeeding segments more elongated. Anal segment wanting 
in the specimens examined. 
Length about 50™™; diameter about 1™™. 
Off Gay Head, 6 to 8 fathoms; fifteen miles east of Block Island, im 
29 fathoms, sandy mud. 
The Clymene urceolata Leidy, from Great Egg Haiioe will probably 
be found on the New England coast, but we have not met with it. It 
is peculiar in having an urceolate anal segment, with a smooth margin.. 
AMMOCHARES, species undetermined. (p. 508.) 
A species which constructs slender, flexible tubes, covered with grains. 
of sand, regularly and curiously attached by one end in an imbricated 
manner, was dredged fifteen miles east of Block Island, in 29 fathoms. 
sandy mud, and in 23 fathoms off Martha’s Vineyard. The worm is 
very slender, flesh-color, with a red dorsal vessel, and two small, red, 
ocelli-like spots. 
NOTOMASTUS LURIDUS Verrill, sp. nov. (p. 342.) 
Body long and rather large, composed of numerous segments, nearly 
cylindrical when living, and tapering but little, except close to the 
ends. In preserved specimens the anterior region, including about ten 
segments, is often a little swollen and slightly larger than the rest of 
the body; at other times it is even more slender than the posterior 
region. Head small, acute. Proboscis short and broad, swollen; in 
full expansion nearly twice the diameter of the body, nearly smooth, 
dark blood-red. The segments of the anterior region are longer than. 
broad, in extension nearly twice as long, biannulated, and each of the: 
annuli is again annulated with several transverse, more or less irregu- 
lar sulci or furrows; ten of these segments bear fascicles of slender 
sete both above and below, the fascicles on the first two setigerous 
segments being very small,.and containing few sete. The segments 
following the tenth setigerous one have a small transverse row of 
slender uncinate sete above, and a longer lateral transverse row of 
the same kind of sete on each side; the “feet,” or setigerous lobes, 
are but little prominent, the upper ones being dorsal and much smaller 
than the lateral ones. The surface of the body is transversely wrinkled,. 
and covered with minute, irregular reticulations, giving it a slightly 
granulous appearance. Color, when living, dark purplish brown, with 
a bluish iridescence anteriorly, and a darker median dorsal line pos- 
teriorly; minute, white, raised spots, or slight papille, are scattered. 
over the surface. 
Length, 150™™ or more; diameter, 2™™, 
Savin Rock, near New Haven; in muddy sand, at low-water mark.
