incisui- are somewhat different from those of the female (see the figures). No surface pores
are visible. In other respects like that of the female.

First antenna: — This is slightly longer relativelv than that of the female.
Bristles of the seventh joint: The b-bristle is about as long as the anterior side of the second
and the third joints; it has five filaments, of which the three proximal ones have suctorial organs.
The proximal one of the three latter have distally of the sucker only an indication of a verruciform
swelling. The two others, which are long and powerful, the distal one of them extending some
distance beyond the point of the bristle, are furnished with from ten to thirteen small suctorial
organs distally, proximally of which there is a small verruca. Distally of the three filaments
just mentioned there are on this bristle two short, bare filaments. The c-bristle is somewhat
longer than the preceding one, attaining about the same length as the anterior sides of the second
to the fourth joints. It has ten filaments, of which the three proximal ones have suctorial
organs; these three filaments are of quite the same types as the corresponding filaments on the
b-bristle; on the two distal ones of them ten or eleven suctorial organs were observed. The
seven distal filaments of this bristle are bare or almost so. Bristles of the end joint: The f- and
g-bristles are subequal, not quite as long as the shell (length of the shell : length of these bristles
about 11 :9); the former has eleven, the latter twelve, filaments, eacli furnished with from
none to four weak secondary spines. In other respects this limb agrees entirely with that of
the female.

Second antenna: — This is slightly stronger than that of the female. E n
dopod i t e (fig. 12): On the first joint this has, besides the group of four proximal bristles, a single
distal bristle as well, of about the same length as the longest bristle in the proximal group.
With regard to this character compare the description of the female given above. In other
respects this antenna is quite like that of the female.

Mandible: — This is very like that of the female. The second endopodite
joint has on the anterior side nine or ten more or less long bristles with short hairs and thirteen
or fourteen cleaning bristles with varying arrangement. The two postero-distal bristles on
this joint are almost equally strong, agreeing completely with those of the female; fig. 5.

The maxilla and the f i f t h limb are like those of the female.

S i X t h limb: — This is very like that of the female, but the bristles are, however,
furnished with softer hairs almost throughout. The numbers of bristles observed were as foliows:
Protopodite: First endite: two or three distal bristles and two medial bristles. The
second endite: two distal bristles and three medial ones. The third endite: four distal bristles
and one medial bristle. The epipodial appendage is represented by three or four
short bristles. Exopodite: The endite on the first joint has six distal bristles and one
medial bristle; the second joint has 17 or 18 bristles; fig. 11.

Seventh limb: — This is very like that of the female. The number of bristles
observed was as follows: seven ventral and from five to seven dorsal ones concentrated distallv;
eight or nine ventral and nine or ten dorsal ones scattered proximally of these.

Penis (fig. 15): ( )f the type character istic for this sub-family; for details the reader

is referred to the accompanying figure.
