through them. Elytron from middle of body broadly ovate, with entire edge (fig. 9) ; point of attach- 
ment to elytrophore visible from above as a colorless area. This nearly or quite surrounded by a band 
of dark brown pigment, from which a band of pigment extends to the edge of the elytron which lies 
on the mid-dorsal line. This pigmented area varies in width from a narrow band to a broad patch, 
from whose anterior end scattered pigment spots may extend; posterior edge more sharply defined, 
convex. A median longitudinal brown line along the dorsal surface of the body, this more prominent 
posteriorly. Parapodia long, posterior ones longer than transverse diameter of body; at the outer 
dorsal angle each is prolonged into equal anterior and posterior ear-like processes, between which 
setse emerge (fig. 10). A large aciculum extends into main lobe, with a smaller one going toward 
dorsal surface. 
Setae all of one kind, long, simple, terminal portion slightly enlarged and bent. On convex sur- 
face of bent portion are two rows of very delicate thin plates, more or less alternating with one 
another; under low power these look like two rows of spines; under higher powder each “spine” is 
seen to be a very thin plate, broader at its distal than at its proximal attached end. Owing to their 
transparency the precise form of these plates is difficult to determine. Their general form is very like 
setae of Polynoe alba. 
Polynoe lucida, new species. (8) Head, x 9. (9) Elytron, 
dorsal cirrus: acii., aciculse. 
: 12. (10) Parapodium, 
c., ventral cirrus; d. c. 
Collected at station 4062, 83 to 113 fathoms, on a bottom of corals, volcanic sand, and shells. 
Type (no. 5202, U. S. National Museum) an incomplete specimen of 60 somites; length, 37 mm.; 
width of head, 1.5 mm. ; width of body at somite 6 with parapodia, 7.5 mm., without parapodia, 4.5 mm. 
Polynoe spicula, new species. 
Head oval, width at base of ceratophores about equal to that of posterior edge; greatest length 
about equal to greatest width, prolonged anteriorly on either side into bases of ceratophores, the latter 
deep brown with colorless apex; antennse slender, length to extreme tip about equal to that of head 
and ceratophore. At about two-thirds of distance from base to tip there is a slight enlargement, 
beyond this the organ tapers rapidly to a very delicate tip; basal half brown in color, with a brown 
band at base of swelling; remainder white. Ceratophore of medium antenna completely filling space 
between those of lateral ones, extending only to a short distance beyond them and colored like them; 
terminal portion like that of lateral antenna, but a trifle larger; eyes two pairs, the anterior slightly 
the larger, and situated on the lateral surface of head; posterior pair near posterior border, and 
slightly nearer median line than anterior; palps extending about as far as median antenna, gently 
tapering, abruptly narrowing to apical portion, which is slender and nearly uniform in diameter 
throughout; tentacular cirri like antennas in form and color.
