af ^ arver ne (Praniza) (Fig. 27) ligner meget Larverne 
‘D ovrige bekjendte Arter, men skiller sig ved en noget

6 . 11101 'kt purpurfarvet Pigment. Legemet er tydeligere 
Dgmenteret end hos Hannen, med smaa og taetstaaende

The 5 free segments belonging to the anterior division 
exhibit, when compared together, about the same relation 
as in the preceding species. The penultimate segment is 
however relatively shorter and broader. Above, it lias the 
usual median longitudinal sulcus, which here, however, occurs 
exceedingly narrow, and, in addition, a, distinctly marked 
transverse sulcus, traversing the former, and on either side 
dividing into 2 branches, that limit the somewhat convex 
lateral region, to the under surface of which are attached 
the corresponding legs. The last segment is perceptibly 
narrower than the preceding, and has the posterior lateral 
corners but very slightly produced, and obtuse. 
The posterior division of the body lias the usual slender, 
linear form, with the epimera but slightly projecting toward 
the sides, as also, saving the terminal segment, divided into 
2 or more teeth. 
The eyes are distinctly developed, but very small, and 
so located that, on viewing the animal from above, they 
appear in great part covered by the minute spikes springing 
from the sides of the head. 
The antennm exhibit nothing distinctive in their struc- 
ture. 
The mandibles have comparatively a somewhat more 
powerful development than in the preceding species, with 
the point a little more incurved and the outer edge smooth, 
without an\- perceptible dentiform projection. 
The oral appendages and the legs do not differ much 
from those parts in the other species. The latter organs, 
however, are characterized, as compared with those in the 
preceding species, by a more powerful structure ami more 
fully developed dentiform projections on the inner margin. 
The pleopoda are, as in the 2 preceding species, wholly 
without bristles on the narrow, linguiform terminal plates. 
The median caudal plate (fig. 2(5) has a very charac- 
teristic form. Immediately posterior to the base, it is ex- 
ceedingly constricted, the outer portion becoming thus very 
narrow and conically pointed. To the point are attached, 
as in the preceding species, 2 diverging bristles, and some- 
what farther anteriorly 2 of a similar kind spring from the 
upper surface. 
The outer caudal appendages are not 'essentially dis- 
tinguished from those in the 2 preceding species. 
Colour a comparatively uniform whity-grey; here and 
there only are observed a few scattered and, as it were, partially 
effaced patches of pigment, having a light-yellowish colour. 
Length 7"”" — therefore considerably greater than met 
with in the preceding species. 
The larva? (Praniza) — (fig. 27) present a close re- 
semblance to those of the other known species, but are 
characterized by a somewhat more thickset form of body. 
The eyes are exceedingly large, occupying the greater part 
of the sides of the head, and provided with a dark purple- 
coloured pigment. The body is more conspicuously coloured 
than in the male, with small and closely disposed red and 
yellow dots, particularly on the abdomen and the foremost 
part of the anterior division of the body.
