Genus VERMILIA Lamarck. 
Vermilia sp. 
A single shell, containing only a few fragments of the animal, too much injured for identification. 
Collected at station 3916, 299-330 fathoms, on bottom of gray sand and mud. 
Family HERMELUD^. 
Genus HERMELLA. 
Hermella varians Treadwell. 
Hermella varians Treadwell, Polychaetous Annelids of Porto Rico, Bull. U. S. Fish Commission, vol. xx, 1900, p. 210, 
fig. 81. 
These had a few less palese on either side than did the specimens from Porto Rico, and the inner 
row of palese was more often three than four on a side. The two large tentacles were easily broken, so 
that few individuals showed both intact. When one was gone, the other looked like a single median 
tentacle. Behind the tentacle on either side is a row of 3 or 4 tentacle-like processes, extending partly 
around the body. 
Collected at station 3909, 308-322 fathoms, on a bottom of fine white sand and mud. 
Genus SABELLARIA Lamarck. 
Sabellaria setosa, new species. 
Head truncated only in a very slightly oblique fashion, with shallow fissure dorsally and deeper 
one ventrally. On either side a single row of about 15 very slender palese, continued around a curve 
near ventral surface so as to form nearly a complete 
circle. First 2 or 3 dorsal ones short, others much 
longer, of uniform length throughout. Palese slen- 
der, tapering uniformly to apex, with what appear 
under low power to be very minute denticulations 
along both sides. Under high power (fig. 78) this 
appearance is seen to be due to a series of rings, the 
outer edge of each forming a protrusion all around 
the palea. These rings relatively more prominent 
toward apex. Interior of palese with numerous fine 
parallel longitudinal lines. 
Dorsally at end of row of palese is on either 
side a row of about 6 short hooks. Each (fig. 79) 
has a thick central axis, curved at apex, and with a 
broad, thin wjng on curved surface. Axial portion 
marked with large numbers of fine longitudinal lines. 
On outer side of head near bases of palese is 
on either side a row of slender, finger-shaped cirri. 
These may differ in size, apparently a result of un- 
equal contraction. Dorsally each row bends around 
so that a few cirri are found between the two rows 
of dorsal hooks. 
Mouth with two large palps, crenulated at the edges. Behind these on either side a broad, rounded 
lobe. Behind this two transverse rows of cirri, 2 or 3 in a row, the anterior larger than the posterior, 
most dorsally placed cirrus of posterior row lying close to base of first gill. A narrow, rounded, and 
rather prominent lower lip lies just posterior to the mouth. 
Gills eight pairs, long, narrow, gently tapering toward apex, the anterior ones largest and over- 
lapping in dorsal middle line, posterior ones smaller. Along both edges of each gill are series of little 
fleshy protrusions of its wall.
