THE POLY CHAETOUS ANNELIDS OF PORTO RICO.

fuses with dorsal surface of head. (See its line of attachment at, in fig. 23.) Parapodia and set* like 
those of E. splendida, except that set* of dorsal ramus are possibly not so numerous and lack the 
brilliant color characteristic of the latter. Second and third segments more or less fused above. 
Arrangement of elytra as in E. splendida , the twelfth pair much the largest, borne on segment 21 and 
covering nearly all the rest of body. 
Elytra white, granular, like those of E. splendida ,, but prolonged on lateral border into broad 
leaf-like processes (fig. 24). One anal cirrus. Number of body segments, 37. 
Length, 24 mm.; width, without parapodia, 4 mm. 
Collected from station 60(51.

According to Ehlers, the ventral cirrus in each segment is fused along its whole dorsal edge to 
ventral face of parapodium. In the specimen from Porto Rico, although the cirrus is closely apposed 
to the parapodium, it is actually fused only at its base. Ehlers describes, further, the parapodium as 
uniramous, with an anterior and a posterior lip, the latter being the larger and bifid at end. In these 
it is the anterior lip which is larger and bifid. 
Through the courtesy of Dr. W. M. Woodworth, I have had an opportunity of examining the 
type specimen from the Museum of Comparative Zoology at Cambridge, Mass., and I find that Ehlers 
was certainly wrong in both the above points. The ventral cirrus in the type specimen is attached 
only at its base, and the anterior lip is larger and bifid. 
In all other respects the Porto Rico specimens agree, with 
Ehlers’s diagnosis of the species.

Phyllodoce magma-oculata, n. sp. 
Head rounded, broader than long (fig. 25). Eyes 
very large (e, fig. 25). Dorsal antennae - lanceolate, nearly 
twice as long as head (d. ant, fig. 25). Ventral antennae 
on lower face of head, equal in size to dorsal. Four pairs 
of tentacular cirri, the largest 3.5 times as long as the 
antennae, thick, with acute termination. The other cirri 
smaller, equal. 
The gills had all been removed from the anterior 
segments of the body. Those which remained were cov- 
ered with a slimy deposit, containing numerous foreign 
particles. The gills are especially liable to be broken 
away in attempting to remove this deposit. Gills broadly reniform (fig. 26), with entire margin and 
with point of attachment near the base of the hilus. Color at point of attachment, light brown. Each 
gill contains numerous anastomosing blood vessels and numerous small, round, light and dark brown 
pigment granules. 
Parapodium a single conical lobe, slightly bifid at the end, with a large aciculum. About nine 
compound set* on either side of the aciculum. Basal joint of set* long, most extending nearly or 
quite the length of parapodium beyond tip of latter. At end the basal portion has a club-shaped 
enlargement, marked by very fine longitudinal lines. Terminal portion rather more than half as long 
as basal, at base as broad as basal portion, tapering gradually to a fine point. 
Collected from station 6067. 
Phyllodoce, sp. 
From Boqueron Bay yvas obtained a fragment of a specimen of this genus too much injured for 
identification, head and tail lacking. The fragment was 25 mm. long, 5 mm. wide, and contained 
over 50 segments. Body black, with a dorsal longitudinal band, and edges of gills and cirri fringed 
with white.
