distal bristles tliere is only one bristle dorsally, situated just in front of the middle of the joint;
this bristle is about as long as this joint. The two distal bristles are somewhat different in length,
somewhat longer or shorter than this joint. All three are of about the sanie type, with one
or a few wreaths of long, stift secondary bristles at the middle and short, fine hairs distally.
The two bristles of the exopodite are somewhat shorter than the distal bristles on the
second protopodite joint, but of about the same type as these. Endopodite: Of the four
ventral bristles on the first joint the shortest one is about half as long as the second endopodite
joint, the three others are about as long as this joint; they are all furnished at the middle with
one or a few wreaths of long, stiff secondary bristles and with short hairs distally. Second
endopodite joint: The anterior proximal group of bristles comprises three bristles, of which the
medial ones are somewhat shorter than the lateral one, the latter being about half as long as
this joint; ail of them are usually furnished with short, fine hairs. End joint: The longest middle
claw is about as long as the second endopodite joint. The anterior claw is only about
a third of this length. The weak anterior bristle in this species is somewhat longer than
the anterior claw. Pilosi ty: The second pro topodite joint and the second endopodite joint
have groups of short, fine, stiff hairs on the outside; similar hairs are also found distally
-anteriorly on the first endopodite joint.
Maxilla: — This is very like this limb in Ph. (Pli.) globosa. Protopodite:
The bristle on the anterior side of the palp on the boundary between the protopodite and the
endopodite is long, being about as long as the endopodite, and has no long secondary bristles.
Endopodite: This has four or five bristles on the first joint distally-posteriorly. The
end joint has three or four c-bristles; the powerful bristles among the b- and d-bristles have
a very weak equipment, almost smootk.
E i f t h limb: — This is very like the corresponding appendage in Ph. ( Ph.) globosa.
In one specimen three bristles were observed on the outer lobe of the third exopodite joint on
this limb of one side.
S i X t h limb: —- Very like that of Ph. (Ph.) globosa. The second exopodite joint
has, on the average, somewhat more numerous bristles.
Sevent h limb (fig. 7) : — This has about the same relative length as in Ph. ( Ph.)
globosa. Cleaning bristles: These are rather numerous, 23—26 being observed; in most cases,
as in Ph. ( Pli.) Lilljeborgi, three dorsal ones and two ventral ones are situated close together
distally, sometimes three dorsal ones and three ventral ones were observed ; the rest are scattered
irregularly proximally of the former ones, being in most cases somewhat more numerous on the
dorsal side of the limb. They are of moderate and somewhat varying length, and are furnished
with from two to five bells, cut off transversally distally; the tongue of the distal bell is also
cut off transversally. Proximally of the bells the cleaning bristles are furnished with from one
to five wreaths of short, stiff hairs, placed obliquely. The end comb (fig. 8) consists of about
twelve to sixteen teeth of moderate strength and length, decreasing somewhat in length the more
proximally they are situated. These teeth are furnished proximally on each side with a rather
strong secondary tooth and are rounded distally; there are no wing-shaped processes at the
sides (such as are found, for instance, in Ph. (Ph.) globosa and Lilljeborgi), or if they do exist,
