Tentacular cirri are long, slender, tapering; the longest reaches back 
to the eighth or ninth segment. 
Dorsal cirri are broad, foliaceous, somewhat imbricated; ventral 
cirri are elongate, prolonged in a slender tip (fig. 8, c,d). The 
setal lobe is long and distally incised and does not extend laterally 
so far as the ventral cirri. Setae have shafts that terminate in a 
finely spinose end, without a major tooth; the appendage tapers and 
is slender and rather short. 
This has been compared with the type specimens (2) of Phyllo- 
doce arenae Webster. ‘They agree closely in all details except one. 
Prostomial proportions are identical, the setal lobe is prolonged 
laterally, ventral cirri are long, pointed, extending distally beyond 
the setal lobe (fig. 8, ¢). Dorsal cirri have the same shape and tex- 
ture, but in Webster’s specimens there is a longitudinal ridge (not 
now so pronounced as was originally shown) near the upper margin 
of the dorsal cirrus, and the glandular striations are less conspicuous. 
In both, the proboscis was originally described with longitudinal 
series of conical papillae, hence belong to Anaitides. 
A. catenula (believed to include P. arenae) is characterized as fol- 
lows: (1) The prostomium is incised at its posterior margin, pro- 
vided with a nuchal papilla, (2) ventral cirri are long, taper to 
slender points, extend laterally beyond the setal lobe, (3) dorsal cirri 
are foliaceous, longer than broad, distally subtruncate, and (4) the 
proboscis has 12 rows of papillae on the basal portion.

In the unique type the eyes are now completely faded; the pro- 
boscis is not everted. There is no indication of a nuchal papilla; 
the posterior border of the prostomium is straight, hence not as 
Augener (1934, p. 127) has described for Anaitides benedeni (Han- 
sen). The peristomial cirri are thick, clavate, subequal in length, 
two or three times as long as the prostomium. Dorsal cirri are 
broadly rounded, much wider than long, with a dark spot near the 
outer ectal margin (fig. 9, c,d). Setae number about 18 in a fascicle 
in posterior fourth of the body. They have a =lender, sickle-like 
appendage; the shaft is distally somewhat thickened but appears 
quite smooth. Ventral cirri resemble the dorsal cirri but are smaller 
(fig.9..d): 
This was incorrectly referred to Anaitides benedeni (Hansen) 
(Augener, 1934, p. 128). The latter was said to have a “herzformige
