The body of the animal carries on each side a well developed 
digitiform filamentary appendage at the base of cirrus I. 
The latter is situated beside the mouth opening, and separated from 
the next cirri by a distinet interspace. 
The cirri are of the common Paralepas -type with five claw- 
like spines at the posterior side of the segments in cirrus II to 
VI. The numbers of segments

The caudal appendages are as long as the protopodite of 
cirrus VI and have 8 segments; only few hairs are present on the 
appendage. 
The penis is stout, tapering, and annulated all over, with few, 
rather short hairs elsewhere, and a tuft of hairs at the distal end. 
It is as long as cirrus VI. 
Of the mouth parts the labrum is furnished at its inner side 
with a single row of rounded denticles. It is 
not bullate. 
The man di ble (Fig. 36) has four teeth, 
the fourth at the lower angle. The second tooth 
is placed only very little above the middle of 
the cutting edge. The second and the third 
tooth have lateral denticles and denticles at their 
lower edge; at the lower side of the fourth 
tooth two denticles are present, representing 
the pectination of the lower angle. The outer 
and lower part of the mandible is densely Fig. 36. Heteraiepas scu-
