SCOLECOLEPIS CIRRATA Malmgren. (p. 501.) 
Annulata polycheta, p. 91, Pl. 9, figs. 54 A-54 D. Nerine cirrata Sars, Nyt. Mag., 
vol. vi, p. 207 (teste Malmgren). 
This is a larger and stouter species than either of the preceding. 
The front of the head is broadly rounded, with prominent, rounded, 
lateral angles; the foliaceous lateral appendages are larger and much 
wider. 
Off Block Island, in 29 fathoms, and in the deepest parts of Vine- 
yard Sound, near the mouth; off Saint George’s Bank, in 110 and 150 
fathoms. Northern coasts of Europe; Spitzbergen; Greenland. In 20- 
250 fathoms. (Malmgren). 
SPIO SETOSA Verrill, sp. nov. Plate XIV, fig. 77. (p. 344.) 
Nerine coniocephala? A. Agassiz, Annals Lyceum of Nat. Hist. of New York, vol. 
vill, p. 333, Pl. x, figs. 39-45, 1866, (non Johnston.) 
Body long, moderately slender, flattened dorsally, convex below, 
obtuse anteriorly, slightly tapered toward the posterior end. Head with 
a prominent median lobe, which is sub-truncate and a little turned up 
at the front end, with the corners a little prominent and rounded; lateral 
lobes shorter than the median; on the posterior part of the vertex 
there is a small median, conical prominence. Eyes four, on the vertex, 
the posterior pair nearest together; antenne long. Branchize moder- 
ately long, slender, ligulate, largest on the anterior segments. On the 
first three or four segments the upper ramus of the feet has a slender 
dorsal cirrus, which disappears farther back. The sete of-the upper 
ramus are long, acute, and form a broad fascicle, in which the upper 
ones are much longer and more slender, divergent; the lower stouter 
and more or less bent; they are longest on the first four or five 
segments, the upper ones considerably exceeding the branchie. The 
lower ramus is small and but slightly elevated; on the anterior 
segments it bears a small fascicle of short, acute, bent sete, much 
shorter than those of the upper ramus, and closely crowded together 
in two or more rows, with a small ventral tuft of longer and more 
slender sete; farther back the acute bent sete begin to be replaced 
by uncinate sets, which, at about the tenth segment, form a complete 
transverse row, parallel with a row of slightly longer, pointed sete, 
while the small ventral tuft of longer acute sete still remains, and all 
the sete in the broad fascicle of the upper ramus are acute and much 
longer. In the middle region of the body, the uncini of the lower 
ramus form a close row, containing fifteen to twenty; they are strongly 
recurved near the end and margined. 
Length up to 80"; diameter about 2.5™™. 
New Haven; Wood’s Hole; and Naushon Island; in sand, at low- 
water. 
This species appears to be the sameas the one studied by Mr. Agassiz, 
though it differs slightly from his figures, one of which I have copied.
