The capitulum has a length of 6 mm, and its width is also 
6 mm; the length of the orifice is 2,5 mm. The peduncle only 
measures 3 mm. 
The filamentary appendages are rather large, digitiform, 
with a somewhat narrower, almost broadly spinelike distal part oc- 
cupying the distal fifth of the free filament. It is situated at the 
base of cirrus I beside the mouth; there is a distinet space of the 
breadth of one cirrus between cirrus I and II. 
The cirri are of the usual Paralepas- type, the claw-like spines 
at the posterior side of cirrus II—VI reaching the length of the 
following segments. The numbers of segments are: 
I II III IV V VI 
Inner ramus 9 14 15 14 15 KV) 
Outer „ 7 13 17 18 18 16 
*) distal part damaged. 
To this must be added that the basal segments of the rami, 
although not especially long, consist of coalesced segments; judg- 
ing by the armature of the named segment, it consists of the fol¬ 
lowing numbers: { n m IV v VI 
Inner ramus 2 4 3 3 2 2 
Outer „ 3 3 4 4 3 4 
If we add these numbers to those given above, the numbers 
of segments in this species agree rather well with Heteralepas per- 
carinata Pilsbry. 
The caudal appendages have 11 segments, and are one and a 
half time as long as the protopodite of cirrus VI. They are siender 
and almost without hairs. 
Penis is short, only half as long as cirrus VI. It is annul- 
ated, stout, and tapers rapidly towards the distal end; the latter is 
furnished with a tuft of hairs; elsewhere only few and scattered 
hairs are present. 
The labrum was damaged in the specimen. 
The mandible has four teeth, the fourth forming the lower 
angle; the second tooth is situated a little above the middle of 
the cutting edge. The second and the third tooth have denticles 
along their lower edge; also the inferior margin of the fourth tooth 
has indistinet denticles, and this tooth moreover carries some small
