c-bristle. The first and second joints are partly furnished with fine spines. These joints have
yellowish-brown corpuscles.
Second antenna: — The protopodite is rather slightly weaker than in
the male. The e x o p o dite is relatively somewhat shorter than in the male, but is otherwise
the same. Endopodite: This is rather distinctly three-jointed. The f- and g-bristles
are of about the same type and relative size as in the male or onlv rather slightly shorter. The
h-, i- and j-bristles are in most cases relatively somewhat shorter than in the male; in most cases
they have no distinct skafts and are furnished proximally with short, fine spines. The f-bristle
too is furnished with short hairs more often than in the case of the male. Between the h- and
i-bristles there is sometimes an exceedingly small papilla, but in most cases it is quite absent.
The second endopodite joint is bare.
Rod-shaped organ: — The stem extends in most cases about as far as half
the length of the capitulum beyond the point of the first antenna. The capitulum is of the type
described by G. W. MÜLLER (see the accompanying fig. 10) and is about one and a half times
or twice as long as the second joint of the first antenna.
Remarks: — The larvae investigated by me belonged to Stages I—III. They measured
3,05—3,3 mm., 2,05—2,2 mm. and 1,3—1,35 mm.
Habitat: — Antar ctic Ocean:

Distribution: — South Atlantic Ocean and Antarctic Ocean between the equator and lat.

The three stations of the ,,A n t a r c t i c“ expedition are conséquent!}- situated within
the area of distribution stated by G. \Y. Müller.
Alata group G. W. Müller.
With regard to this group I hold quite the same view as lias been put forward by
G. \Y. MÜLLER, 1906 a, p. 121. It may be taken as quite certain that (’. l{(/<jicae belongs to il.
