areas VI. Each area VI has six or eight similar 
cones, and area V has three slightly larger cones 
than those on area VI. The largest paragnaths 
of the oral ring are those on the maxillary side 
of area VI. On the maxillary ring, area I has a 
single small cone, area II has a narrow crescent 
of four or five small cones; III has an oval patch 
of about 18 cones, including four larger ones 
on the oral side and others of varying sizes; the 
largest are about equal to those on the maxillary 
side of area VII; area IV has a crescent of about 
14 in approximately two rows intermediate in 
size between those of III and II. Jaws are trans¬ 
lucent, dark, horny, brown, and thick; there 
are 12 short, crenulate, slightly oblique teeth 
along the cutting edge. 
The first and second parapodia are uniaci- 
cular and uniramous as typical of the genus. 
From the third, slender dark acicula occur singly 
in each lobe and are continued so throughout. 
Anterior parapodia have nearly equal dorsal, 
middle, and ventral ligules; there is no ligule 
in the notoacicular portion; the neuroacicular 
lobe is shorter than the parapodial ligules; the 
dorsal cirrus is inserted at the base of the dorsal 
ligule and extends distally about as far; the 
ventral cirrus is shorter than the ventral lobe. 
Parapodial ligules change little proceeding 
back except for the dorsal one; already in the 
anterior third of the body it increases in width, 
surpassing the others in size and by the middle 
it extends distally beyond the others. The inser¬ 
tion of the dorsal cirrus is gradually outward 
and comes to be about midway on the dorsal 
ligule (Fig. la). 
Setae are of the usual kind. Notopodia are 
provided with only homogomph spinigers in 
anterior segments; from about segment 40 there 
are one or two homogomph falcigers (Fig. 7 
c) accompanying the spinigers and they finally 
replace the latter. At their greatest develop¬ 
ment the falcigers number five or six in median 
segments, but the number decreases further 
back. Under low magnification these hooks ap¬ 
pear dusky. Neuropodia are provided with 
homogomph spinigers superiorly, and with 
heterogomph falcigers (Fig. 7 b) and hetero- 
gomph spinigers below the aciculum.
