BARBADOS-ANTIGUA REPORTS fe 
Haplosyllis gula new species 
Collected at Station 101 and when they reached me attached 
to the surface of fragments of Leodice longicirrata Webster ; to 
a small Glycerid, and to another Syllid, though most of the 
specimens were on the Leodice. They were usually attached 
to the body wall rather than to cirri and evidently held in place 
by a strong sucking action of the pharynx for when pulled 
loose the point of attachment on the body wall showed as a 
very distinct papilla. Eisig (1906 page 180) and Potts (1911, 
page 410) have described the ferocity with which syllids at- 
tack other annelids and it is possible that the attachment took 
place in the close confinement of the collecting dishes rather 
than in the open ocean. I have elsewhere (1909, pages 359, 360) 
shown that Haplosyllis cephalata Verrill may establish a rela- 
tively permanent attachment to other annelids, for the cirrus 
held in the jaw of the syllid has evidently been digested. In 
the specimens here described there was no evidence of anything 
more than temporary attachment. 
Under low magnification the most noticeable feature of the animal is 
the reddish-brown pharynx with its darker anterior margin which in all 
of the specimens was so far protruded that its anterior end was level 
with the anterior margin of the prostomium. (Figure 22) 
One entire specimen has 32 somites with a pair of unjointed anal cirri 
(figure 23). The body is widest at the anterior end and gradually nar- 
rows posteriorly. The total length is about 2 mm. with a prostomial 
width of less than 0.25 mm. The palps are separate to their bases (figure 
19), are together broader than the prostomium and are longer than it. 
The prostomium is short, its length being about one-third its width and 
its anterior margin is rounded. On either side are two reddish-brown 
eyes, the anterior of each pair larger than the posterior and considerably 
farther from the mid-dorsal line. Only the median and one lateral ten- 
tacle are present in the specimen figured and as this seemed to be the best 
preserved one of the lot, these are drawn. The median tentacle is a little 
larger and longer than the lateral and both are moniliform. The dorsal 
tentacular cirrus is about the size of the median antenna while the ventral 
one is very short, (not shown in the drawing). The first dorsal cirrus 
is larger and longer than the dorsal tentacular, and larger than most if 
not all of the other dorsal cirri, though there is not the decided decrease 
in length posteriorly which Verrill (1900, pages 613 and 614), described 
for Haplosyllis cephalata. The preservation is however too poor to allow 
of accurate description of most of the dorsal cirri. The parapodia are in 
length about equal to one-quarter of the body width and taper gently to 
the rounded ends. The ventral cirrus is lanceolate in outline and its
