End claw very poweri’ul, about as long as the anterior side of the second endopodite
joint, smooth.
Maxilla (fig. 6) : — Protopodite: The distal endite is armed with three bristles.
the middle one of which is usually somewhat shorter tlian the other two. The dorso-proximal
bristle is moderately long. The ventral bristles on the basale vary both with regard to number
and position not only from one individual to another but even on the right and left maxillae
of the same specimen; from four to seven of these bristles were observed; of moderate and
somewhat varying lengths. In addition the basale has three subequal and rather short
dorso-distal bristles. The short ventero-distal bristle of this joint is developed.
Endopodite: The posterior distal bristle of the first joint is somewhat shorter than the bristle
on the end joint.
Sixth li mb — The posterior edge is rather well rounded, the posterior
ventral corner is rather broadly rounded. There are 22—24 postero-ventral bristles and
five or six antero-ventral bristles. On the anterior edge only one bristle, the upper one,
is developed.
Sevent h limb (figs. 11—13): — This is armed with 22—26 cleaning bristles
of moderate and somewhat different lengths, scattered fairly regularly along the distal
part of the limb. The number and position of these bristles vary both from one individual
to another and from the right to the left limb of the same individual. Each cleaning
bristle has from three to five bells. Each end comb consists of 17 —19 teeth. All these
teeth are of the same type, closely and evenly pectinated; they are strengthened distally;
ci. hg. 13.
Furca: — This has eight or nine claws ; of the three specimens investigated two had
nine, the third, the type-specimen, had only eight, one of its secondary claws was absent, but
I could not decide if the specimen in question was defective, which is, however, not improbable.
Of these claws the six or seven anterior ones are to be denotecl as main claws. The hrst and second
main claws have no ventral basal teeth. One or two of the posterior secondary claws are
annulated.
The lateral e y e s are well developed. The m e d i a n e y e is smooth.
The male is unknown.
Specimen no. 3. Right
