BULLETIN OF THE IT NT TEL) STATES FISH COMMISSION. 
First parapo lium with a pair of long cirri and with long delicate setse minutely serrated along 
the edges. Other parapodia with a pointed ventral cirrus. (Fig. Hr. c. ) On segments without elytra 
a broad dorsal cirrus; on those with elytra the elytrophore carries a narrow cirrus on its outer sur- 
face (fig. 11 cir). Lobes of parapodium thick, blunt. Setse on dorsal lobe arranged in a row; those on 
ventral lobe in a partial spiral. End of lobe prolonged into leaf-like processes. Similar processes may 
occur on dorsal surface of parapodium. (Fig. 11 tub.) In this figure of the parapodium no attempt 
has been made to represent the 
curved arrangement of the ventral 
setae. Dorsal setae long, capillary, 
with delicate serrations along their 
edges. Ventral setae of two kinds; 
first compound, with long, smooth, 
terminal joint (fig. 12) ; second, 
few in number, complexly fringed 
along their edges (fig. 13). 
Pharynx, when everted, with 
an upper and lower “valve,” each 
with eleven papillae. Two brown 
teeth above and below. There are 
two anal cirri. In some specimens 
many of the anterior elytrae bear 
orange-colored pigment spots. 
This is apparently closely 
related to S. luxuriosa of Grube 
(Annulata Semperiana, p. 54), but 
differs in fringing of elytra and in 
structure of setae. One specimen of 28 segments was 14 mm. long. None were complete, some bottles 
containing only anterior, others only posterior ends. 
Collected from stations 6057, 6059, 6061, 6062, 6063, 6073; Puerto Rico, Boqueron Bay, and San 
Antonio Bridge, San Juan.

Psammolyce rigida Grube, Verhand. d. Zool.-Botan. Gesellschaft in Wien, 1868, p. 631, pi. 7, fig. 1. Quoted from Grube, 
Annulata Semperiana, p. 55, 1878. 
Collected from station 6062. 
PANTHALIS Kinberg. 
Panthalis oculea, n. sp. 
Head globular, prolonged anteriorly into two eye-stalks, which carry the enormous eyes (fig. 14). 
Three tentacles, the median on anterior margin of head, the paired beneath the eye-stalks and project- 
ing beyond'their ends. Apex abruptly narrowed, giving rise to moderately long filament, longer than 
terminal filament of unpaired. Palps long, tapering, surface covered with minute filiform processes. 
First parapodium with two long cirri, ending like the unpaired antenna, and nearly as long as 
the palps, but more slender, and smooth. Palps and cirri with numerous brown dots. A tuft of setae 
on dorsal surface of first parapodium. A brown marking at base of unpaired antenna and a transverse 
brown band at posterior edge of head. Smaller pair of eyes near base of antenna. 
Elytra on segments 2, 4, 5, 7, etc., through as much of the body as was preserved. Elytra nearly 
round, small, leaving the greater part of the body uncovered, their surface divided by fine lines into 
nearly equal, rectangular “cells.” A brownish pigment in many of these spaces, with a tendency to 
accumulate in greater amount toward dorsal and posterior edges. Two specimens, otherwise indis- 
tinguishable from the others, showed no pigment on the dorsal surface of elytra and the posterior 
edges of the latter were black. 
Pharynx, when extruded, as long as first 20 segments, with a smooth surface; at end with a 
dorsal and ventral “valve,” each fringed with papilhe, of which the dorsal and median ventral are 
much the largest. Two powerful teeth in each jaw, a row of smaller teeth running laterally on either 
side of each.
