ö i X t h 1 i m b (tig. 13): — The posterior edge is in most cases almost straight; the
posterior ventral corner is, however, well rounded; 23—28 postero-ventral bristles, six antero-ventral
bristles; the anterior edge has two bristles.
The seventh 1 i m b (fig. 14) is practically of quite the same type as in the preceding
species. From seventeen to twenty cleaning bristles, from eight to ten on each side, were
observed. On one specimen only two bells were found on one cleaning bristle. Each end comb
consists of from sixteen to eighteen teeth.
Furca: — This has ten claws, of which the eight anterior ones may be denoted as
main claws. The two anterior main claws have no basal teeth ventrally. The secondary claws
are annidated.
The lateral eyes are well developed. The median eye is smooth.
Male unknown.
Remark: — This species resembles very closely with regard to the shape of its shell

is certainly not a real unit, as is shown, among other things, by the length of the shell, 2,1 mm.,

the relation of the species described by me above to the specimens on which these three
accounts are based, on account of the deficiency of the descriptions given by the above writers.

Description: — F e m a 1 e : -
Shell: — Length, 1.37—-1,41 mm.; length : height about 1,42:1; length : breadth
about 2:1. Seen from the side (fig. 1) it is somewhat pear-shaped, with its greatest
height just behind the middle and the back part strikingly larger than the front. The dorsal
and ventral margins are almost of the same shape, moderately and uniformly curved, somewhat
flattened anteriorly; they pass evenly into the anterior and posterior margins. The posterior
parts of the dorsal and ventral margins form, together with the posterior margin, almost a semi-
This species is called after Professor O. W. Mülleb. oiir foremost investigator of the Ostracod group.
