material it is highly iridescent and the reddish segmental or- 
gans are very prominent. Because of this firm wall and eylin- 
drical form and because the parapodia with their cirri and the 
tentacles are very small and inconspicuous, the animal when 
alive looks more like a nematode than a polychete. This re- 
semblance is heightened by the character of its movements 
which because of the elasticity of the body are quite similar to 
those of nematodes. 
The proboscis was thrown out in most of my material from 
Tobago. It is stout, about 6 times as long as the prostomium 
and with a soft margin. The pharynx is very long. 
Collected at Station 99, at Ft. Barclay and at English Harbor.

Nereis glandulata Hoagland 
Nereis glandulata Hoagland, (1919), p. 575, pl. xxx, figs. 1 to 6. 
Five specimens and some immature ones that are evidently 
of this species were taken at Pelican Island; ten at Bathsheba, 
one at Pillars of Hercules, and one in ‘‘old coral heads.’’ 
Nereis gracilis Webster 
Nereis gracilis Webster, (1884), p. 313, pl. LX, figs. 29 to 35. 
One incomplete specimen in three pieces was taken at Station 
99 and a young specimen at Pelican Island. 
LEPTONEREIS Kinberg 
Leptonereis egregicirrata new species. Heteronereis phase 
Small heteronereids not over 15 mm. long, which I have assigned to 
this sub-genus because of the absence of paragnaths. The prostomium 
is bent in all cases so that the palps point directly ventrally. The eyes 
are very large, purple in the preserved material and have prominent 
lenses. The tentacular cirri are rather short, the longest not reaching 
farther than setigerous somite 6 and the shortest barely longer than a 
somite. The longest is the postero-dorsal, the shortest is the antero- 
ventral. 
The female (whose entire body is distended with eggs), has in the 
anterior region very feebly developed parapodia and those in the pos- 
terior region are small and closely pressed against the side of the body. 
Across the peristomium and the anterior 12 setigerous somites are traces 
of what must have been in life a prominent transverse band in each 
somite. Beginning on the 4th setigerous somite and continuing poster- 
iorly there is a prominent pigment spot just dorsal to the parapodium on 
either side in each somite. Posterior to the 12th setigerous somite there 
is a tendency for the transverse band to break up, the apex of the band
