Sub-Genus Doloria n. sub-gen.
Description: — Shell: — Its form is somewhat different in male and female, though
this difference is rather slight. — It is oval without or with onlv a weakly developed posterior
corner. The rostral incisur is narrow and comparatively deep; near the inner edge of the incism
there are two medial bristles situated close to each other. With rather strong calcification.
The species of this sub-genus hitherto known are moderatelv large.
First antenna: — This is long, siender and has eight joints; for the proportion
between the joints see the diagnosis of the sub-familv. The sensorv bristle of the fifth joint
has thirteen sensory filaments. Three of the filaments on bristles b and c are modified in the
male for seizing the female. Of these three filaments, all proceeding from the medial side of
the bristles, the proximal one issues just at the base of the bristles; this is short and powerful,
swollen at the base and strongly chitinized distally, almost spine-like; medially at about half its
length it has a single suctorial organ. The two other filaments are relativelv long and have
distallv-mediallv on one side a series of small suctorial organs all of about the same type and size.
The end bristles are not much longer in the males than in the females.
Second antenna: — The protopodite has one medial-distal bristle.
Exopodite: The bristle of the second joint is rather powerfully developed. The natatorv
bristles on the third to the ninth joints are quite without spines. The third to the ninth joints
have basal spines. Endopodite: In the male this branch is developed into a powerful
triple-jointed clasping organ, the end joint of which has, besides the proximo-ventral bristle,
two very short distal ones as well. In the female it is comparatively rather well developed,
elongated, and triple-jointed; its end joint is, however, sometimes rather weaklv marked. The
bristle of the end joint is long.
Mandible: — Protopodite: The endite on the coxale is simple distally or
has onlv indications of bifurcation; its spines are partly rather powerful. especially those situated
distallv-mediallv and have onlv rather a slight tendency towards arrangement in groups. Apart
from the bristle of the endite there are no bristles on the coxale. Basale: Of the ventral bristles
one d-bristle is very long, has numerous long secondary bristles and is furnished with short
hairs distally, the rest vary from being moderatelv long to very short and have generally short,
fine liairs or are quite bare. This joint has three or four bristles dorsally. Endopodite:
The first joint has four bristles ventrally. The end joint has six or seven bristles, one of the
posterior ones may be missing; — this is noteworthy, as in all the other forms of this sub-familv
dealt with in this work, as well as in the species of the sub-familv Philomedinae, seven bristles
are always developed on this joint —: the two middle of these bristles are rather powerful,
claw-shaped, and about as long and as strong as each other.
Maxilla: — Protopodite: The coxale has dorso-distallv a single bristle with
long and fine hairs. Proximally on the outside of the third endite there is a single bristle. On
the boundary between the basale and the first endopodite joint there are three bristles, one close
to the exopodite, one at about the middle of the inside of the endopodite and one on its anterior
