In the larger specimen the capitulum measures 15 mm with 
a width of 12 mm; the peduncle is 10 mm long. The smaller spec¬ 
imen has a capitulum length of 8 mm, and a width of 6 mm, 
whereas its peduncle is 5 mm; the latter is not quite intact. 
A dissection of the smal¬ 
ler specimen gave the fol- 
lowing results. 
The, fi 1 amentary ap- 
pendage is short and 
stout, situated at the base 
of cirrus I. There is only 
a narrow interspace be- 
tween cirrus I and II. 
The cirri show the typ- 
ical Heteralepas. In cirrus 
I the inner ramus has 11, 
the outer 17 segments,

the basal segments evid¬ 
ently representing 2, respectively 3 coalesced but not very long 
segments. The inner ramus is a little shorter than the outer one, 
but is of the same width; the segments are bullate in both rami. 
— In cirrus V the rami are very unequal: the stout outer ramus 
has 42 segments of which the basal long one evidently consists of 
8 coalesced segments; the very siender inner ramus has only 11 
segments and is only in the outer segments armed with few hairs. 
In the same way cirrus VI has an outer ramus of 38 segments, 
the long basal segment evidently again consisting of 8 coalesced 
segments; the more threadlike inner ramus consists of only 10 
segments. 
The caudal appendages are very short, only as long as 
the basal segment of the protopodite in cirrus VI; they have 7 
and 5 segments. 
Penis is short and stout, only half as long as cirrus VI, an- 
nulated throughout; it has few and scattered hairs, and a tuft of 
hairs at the distal end. 
The labrum is not bullate; it is armed with a single row of 
rounded denticles along the oral margin. 
The mandible (Fig. 38b) has four teeth, the lower constitut-
