Upper pair of longer spines about as long as lower pair. Behind the upper pair, there is a 
distinct notch, which in one specimen is smaller than in the other. The inferior pair cannot 
be said to be placed on a special projection — yet it is situated somewhat above the 
level of the other spines, and a small notch, in some specimens, also separates these two 
spines from the middle ones. Between the upper and inferior pairs 5 to 6, spines are 
disposed along the edge. These are much shorter and thinner than those of the upper and 
inferior pairs. 
Outer maxillae (Pl. XVII, fig. 12) with the outer lobe rather broad, certainly not 
much longer than it is broad, the extremity towards the interior side bluntly pointed. Hairs 
cover densely a large part of the inner surface towards the extremity and along the distal 
margin. A longitudinal group of hairs can be seen to extend over the middle of the said 
surface to the inner lobe. The latter bears several rows of hairs, of which those disposed along 
the inner margin are, as usual, directed towards the basis of the maxilla. 
Cirri. First pair has unequal rami of 9 and 15—17 segments. The 7—8 lower 
segments of the longer ramus form a broader basal part, the 8 to 9 remaining segments are of 
a more elongate shape. The 3" to 7t® middle segments of the shorter ramus have the inner 
face distinctly protuberant, and dense tufts of hairs are disposed on these protuberances. 
Second pair has 9 to 10, and 10 to 12 segments in the two rami, the lowest segment 
of each ramus being indistinctly composed of three segments. The segments are very protuberant 
on their inner faces, and the hairs disposed on these protuberances are long and form very 
dense tufts. 
Third pair has the rami slightly more unequal of 11 (12) and 13—15 segments. The 
segments have the inner or anterior face rounded, but not distinctly protuberant; the tufts of 
hairs disposed on the anterior face less dense than on the 2" cirrus. No teeth are observable 
on the surface of the rounded anterior face. 
Fourth pair: number of segments 26 to 27. Three pairs of spines along inner face 
of middle segments. 
Sixth pair: number of segments 27 to 29 — in several specimens, however, the cirri 
of the last pairs are broken off. The middle segments (Pl. XVII, fig. 13) are slightly longer 
than broad, with the inner face somewhat rounded and bearing four pairs of spines, the third 
of which is considerably shorter than the 1st (the most distal one) and the 24, the fourth (the 
basal one) being quite rudimentary. The hairs disposed on the dorsal face, close to the upper 
margin of each segment, form a group of two or three, one of which is longer and somewhat 
thicker than the others. 
Penis has several hairs scattered over distal part, and a rather dense tuft at the 
extremity; near its basis the dorsal side bears a short blunt tooth. 
This species was taken by the Siboga at two Stations, which are not very distant from 
one another: 
Stat. 49". April 14, 1899. Lat. 8° 23'.5S., Long. 119° 4.6 E. Depth 69 m. Sapeh-strait. Bottom: 
coral and shells. Numerous specimens, attached to pieces of wood that are 
much perforated by Zeredo.
