The peduncle is short, and broad, covered by a smooth 
cuticle which exhibits no trace of scales or hairs of any kind. 
The peduncle even may be shorter than in the specimens figured. 
The first cirrus is placed at a little distance from the second; 
its rami are unequal, the shorter with 10, the longer ramus with 
12 segments. The cirri II—VI are long, and strongly curved, with 
equal rami; in the cirrus V each ramus has about 20 segments. 
Caudal appendages are present; they are small, consist of one 
segment with one great hair at the base, and two or three hairs 
at the distal broad end. 
The well developed penis attains a length of of cirrus 
VI; it is not annulated, but has some small hairs scattered all 
over. 
Of the mouth feet the man dible has three larger teeth, and 
between the first and second teeth two smaller ones; the lower 
angle is rather pointedly rounded and finely pectinate. The inferior 
part of the mandible is richly furnished with hairs; at the upper 
side a small tuft of hairs is seen. 
The maxi 11a has two stronger and one smaller spine at the 
upper angle; there is a distinet notch between the upper spines and 
the group of large spines which occupy the median third of the cut- 
ting edge; the lower third of the edge is armed with short and 
stiff bristles or hairs. The surface of the maxilla is richly adorned 
with fine hairs. 
The outer maxi liae are obovate, with rather pointed ends; 
the interior margin has large, hairlike spines on its outer part. 
Several specimens were found attached to a siliceous sponge 
which forms a hard erust. The largest specimens had a capitulum 
length of 12 mm; the width of the capitulum is 7, the lateral 
axis at the base 4 mm; the peduncle only reaches a length of 
2,5 mm. 
Complemental males are present. They have a distinet ped¬ 
uncle, and capitulum, the latter with a well developed skeleton, 
consisting of carina, terga, scuta, and rostrum; the primary valves 
have the primordial, chitinal plates at the apex. The shape of the 
terga is peculiar, the primordial valve forming a beak-like process 
at the anterior side. Carina and rostrum are triangular with
