NICIDION Kinberg. 
Nicidion brevis Ehlers. 
Nicidion brevis Ehlers, Annelids of the Blake, p. 98, pi. 28, figs. 9-14; pi. 29, figs. 1 and 2. 
Collected from station 6085, Mayaguez, Puerto Real, Cabal lo Blanco reefs, and Ensenada Honda, 
Culebra. 
LYSIDICE Sav. 
Lysidice sulcata, n. sp. 1 
Head deeply bilobed (fig. 47). (L. notata Ehlers, Annelids of Blake, p. 100, to which it seems 
to be closely related, shows no trace of this lobing. ) 
Tentacles three, middle one the longest. Eyes dark 
brown, just^outside of outer antennae. Roughly 
crescent-shaped, posterior end of crescent the larger. 
Peristomium about four times wider than long. Sec- 
ond segment about half as long as buccal and slightly 
wider. Successive segments widening gradually to 
the sixth, which is as wide as greatest width of body. 
Parapodia first appear on third segment. Anterior 
parapodium uniramous, with dorsal capillary and 
ventral jointed sefae. The terminal joint short and 
toothed (fig. 47a). A single aciculum. Posterior 
parapodia with two aciculpe and comb-shaped sefee 
(fig. 48). In other respects like anterior ones. 
The specimen was incomplete, having lost the 
posterior end; 102 segments present. At the head 
the animal was 2 mm. in diameter; length 23 mm. 
This differs from L. notata in the cleft condition of the cephalic lobe and in the presence of comb- 
shaped setse on posterior parapodia. Anterior end deep reddish brown (in formalin). Cephalic lobe 
and tentacles very light brown. 
Collected from reefs at Ponce and stations 6065 and 6079. 
Family GLYCERIDE. 
GLYCERA Sav. 
Glycera abranchiata, n. sp. 
Head of usual form, narrow, not noticeably segmented, about one-third as long as extended 
proboscis. Four delicate tentacles. Proboscis smooth at base, but for 
greater part of its course covered with minute papillse; at end, with a row 
of much larger papillse. Four strong, black teeth. Segments biannulate, 
increasing gradually in width up to about the twenty-fifth, which is five 
times broader than long. From here the body gradually decreases in 
width, that of posterior segments equaling their length. Two anal cirri. 
The parapodium of the twenty-fifth segment is equal in length to about 
one-fifth of the diameter of the body. Those of the posterior end of the 
body equal in length to whole width of body. The anterior end of 
body cream color, posterior end much thinner and transparent. Para- 
podium of first segment very small, others increasing in length up to 
the twenty -seventh. Each (fig. 49) with two rounded posterior, and two 
much longer, pointed, anterior, lips. The ventral cirrus is broad with an 
acute apex; dorsal cirrus small, rounded, situated on t he body wall. A dorsal and a ventral aciculum. 
1 Since the manuscript for this paper was sent to the printer, I have received from Professor Verri 11 his paper on 
Additions to the Turbellaria, Nemertinea, and Annelida of the Bermudas, Trans. Conn. Acad. Sci., vol.x, pt. 2, Nov., 1900. 
This paper is not accompanied by figures, but from the descriptions I am inclined to believe that this species may possibly 
be identical with Verrill’s Lysidice bilobata.
