Eunice, sp. 
Fragments of Eunice, too much injured for identification, were collected from Arroyo; stations 
LUMBRICONEREIS (Blainville) Ehlers. 
Lumbriconereis parva-pedata, n. sp. 
Head acute, about as broad as long. Dorsal surface marked by median longitudinal ridge. No 
eyes. (Fig. 38.) First two segments short and nearly fused, the line between them more apparent on 
the side than elsewhere; the two together only a little longer than the third. Junctions between 
anterior segments as far as ninth not marked by any prominent constrictions. From the ninth 
onward these intersegmental constrictions become very deep and the segments are much shorter, not 
more than half as long as broad. Width of body increases up to segment 10; then decreases slowly to 
segment 25; from here the diameter is nearly uniform, tapering gradually toward posterior end. 
Segments behind twenty-fifth a little longer than those in front.

Fig. 41. — Head of Lumbricon- 
ereis floridana , x 18. 
Parapodium of first segment very small, forming a mere knob on side of segment. Second para- 
podium a little longer, containing two or three stout, hooked setse (see fig. 39), and two (only one 
shown in fig. 39) long, capillary setse with broad, striated apex. Parapodia of anterior segments too 
short to be visible from a dorsal view. They gradually elongate toward posterior end, coming into 
view from above on the eighteenth segment. Parapodium of nineteenth segment (see fig. 40) has 
rounded anterior and more pointed posterior lips. Four dorsal broad capillary setse and two ventral 
stout hooked setse. The setse of most of posterior segments had been lost, so that no data can be 
given concerning any variations that may occur among them. 
Length, 200 mm. Width at anterior end, 2 mm. 
Color in alcohol, light yellow, with yellowish brown bands crossing many of the segments. 
These bands are very irregularly distributed and may be portions of the color of the living animal 
which had not been entirely extracted by the alcohol. 
Collected from Ensenada Honda, Culebra. 
Lumbriconereis floridana Ehlers. 
Lumbriconereis floridana Ehlers, Annelids of the Blake, p. 103, pi. 30, figs. 10 to 15. 
Collected from Boqueron Bay and station 6065. From the latter locality was collected the 
anterior portion of another specimen, differing from Ehlers’s diagnosis in the more pointed head lobe. 
(See fig. 41.) Since it agrees in other respects, I have included lit in this same species. 
Lumbriconereis maculata, n. sp. 
Head rounded, a trifle longer than broad, as long as following three segments. Surface uniformly 
convex, with al >rupt depression at posterior margin. No eyes. ( Fig. 42. ) First segment twice as long 
as second. First nine segments about five times as broad as long. Beginning with the tenth there is
