narrower towards 
: r margin isa little 
hollowed out. Surface partly covered with hairs. These hairs are dis densely towards 
distal extremity, where they form a kind of a tuft. Downwards, i tion of the inner 
lobe, a very conspicuous row of hairs is seen, most of which stand izontal direction. 
Inner lobe of oval shape, not much elongated; in one of the sp shape is hardly 
longer than broad. Hairs disposed on inner lobe not so numerous ite so long and 
stout as in most other species of the genus. 
Cirri. First pair has unequal rami of 6 and 12 segments in 13 in another 
specimen. Segments cylindrical, hardly protuberant, those of the s us are slightly 
broader than those of the longer ramus. 
Second pair has short rami of 5 and 7 segments respectively; segments not protuberant, 
but having the anterior face rounded; shape of segments as a whole almost circular. Tufts of 
hairs along rounded anterior faces not very dense. 
Third pair has somewhat longer rami of 6 to 7, and 8 segments, each segment being 
about one and a half times as long as broad. The anterior face of the segments swollen and 
bearing along that swelling or protuberance (Pl. XXI, fig. 12) a row of teeth, which from the 
base to the upper end increase in size. These rows of teeth are present along segments 2 to 5 
in the one, and segments 2 to 6 in the other ramus; near the upper margin of the segments 
each row ends in a curious minute comb formed by a horizontal row of very small teeth. Last 
segment of pedicel shows very minute teeth along anterior margin, near the extremity. 
Fourth pair has rami of 14 and 16 rather elongate segments; last segment of 
pedicel quite unarmed; the anterior face of the middle segments of the shorter ramus bears 
only two pairs of spine-like hairs, the lower segments have only one pair and a pair of much 
shorter hairs; the anterior face of the latter segments (Pl. XXI, fig. 13), near the distal extremity, 
is furnished, moreover, with 2 to 3 somewhat recurved teeth. The middle segments of the longer 
ramus always have three pairs of such spine-like hairs. None of the segments of the longer 
ramus are furnished with teeth. 
Fifth pair has 20 rather long segments in each ramus and, in the middle of the 
ramus, each segment furnished with 4 pairs of hairs on anterior face. 
Sixth pair has 21 and 23 long segments in the two rami, and 4 pairs of hairs on 
anterior face of the middle segments (Pl. XXI, fig. 14). The first segment of the pedicel of 
this cirrus has the posterior margin distinctly serrated.
