mens, with long filiform tips, at other times shorter, subacute ; their length 
even in preserved specimens often exceeds the height, or the transverse 
breadth of the body ; the inner ones are larger and stouter ; the outermost are 
much smaller, but long and slender, or almost filiform. 
The color of the column varies from pale salmon to deep salmon and brown- 
ish orange, corresponding, in all cases, very closely with the color of the 
Acanella on which it is found. Tentacles usually darker than the body, often 
orange or orange-brown, sometimes light salmon, but frequently dark purplish | 
ce n, with paler tips. Disk similar to the tentacles, usually salmon radially 
streaked with brown; mouth large, often everted, frequently brown. 
The larger examples have the longer diameter of the body above the base, 20 
to 25 mm. ; transverse diameter, 12 to 15 mm. ; height, 10 to 15 mm. ; length 
of tentacles, 10 to 15 mm.

This species has also been dredged*at numerous stations, in 219 to 506 
fathoms, off Martha’s Vineyard, by the U. S. Fish Commission, often in large 
numbers, on Acanella, which is common there. 
It has also often been brought in by the Gloucester fishermen, since 1878, 
from many localities.on the deep fishing banks, off Nova Scotia, and from the 
Grand Bank. A similar species, possibly identical, occurs on deep-water gor- 
gonians dredged by the Blake among the Antilles. 
Sagartia spongicola VerRItt, sp. nov. 
Plate VI. Fig. 3. 
A small, rather cylindrical, smooth, rosy or flesh-colored species, with a 
moderate number of tentacles, which are not very long. 
Column, in extension, higher than broad, round, usually nearly cylindrical, 
but frequently changing in form. Base small, often rather broader than the 
column, flat, or clasping sponges, hydroids, ete. Tentacles not very numerous, 
arranged in two, three, or more rows, close to the margin, leaving a large part 
of the disk bare ; they are rather small, a little stout, not very acute, variously 
curled, Acontia have not been seen ejected, but there are a few small, pit-like 
openings on the sides, which appear to be pores (cinclide). Some specimens 
show small verruce near the summit.- The internal lamella show as white 
lines through the sides of the body.
