S. e co n cl antenna: Exopodite: The natatory bristles have no spines and there
are no basal spines. Ëndopodite: The two proximal joints in the female have no bristles.
Mandible: The endite of the first protopodite joint lias a moderate number of
comparatively weakly developed ventral spines and bristles. The second protopodite joint
and the second endopodite joint hâve a moderate number of bristles.
Maxilla: This has few or no bristles dorso-proximally on the basale.
Sixth limb: Seen from the side, this appendage has both an anterior and a posterior
pointed corner.
Seventh limb: This has a moderate number of cleaning bristles, in most cases
only one on the same side of the saine ring.
The furca has three long, curved, rather siender main claws, behind whieh there
are a number (always rather few?) of considerably shorter and weaker secondary claws.
This genus includes two of the species placed by G. IV. MULLER, 1912, in the genus
Cyclasterope, viz. :
Cypridina Agassizi, Fr. MÜLLER, 1870, p. 255, pi. VIII, fig. 26, pi. IX.
Aster ope fusca, G. W. MÜLLER, 1890, p. 242, pi. XXV, figs. 11—13, pi. XXVII, figs. 19 to
22, 25.
It is possible that Cyclasterope Liguriae, L. Granata, 1915, p. 30, fig. 5 is also to be
included in this genus; the position of this form is, however, verv uncertain on account of the
deficiency of the description.
Type species: Asteropleron fuscum (G. IV. MÜLLER).
A number of other species are described, of whieh it may certa inly be said that thev
belong to this family, but whose position, apart from this, is unknown on account of the
incom-pleteness of the descriptions. Among these there are:
Cypridina Adamsi, W. Baird, 1847, p. 22, pi. VII. This species is included, as is seen
above, in the genus Asterope by G. W. Müller, 1912; it does not seem to me impossible that it
belongs to the genus Cyclasterope. G. V. Müller writes: „Vielleicht identisch mit A. Hilgendorft?“
Asterope lichenoides, G. S. BRADY, 1902 a, p. 180, pi. XXIII, figs. 22—24. This species
was also included in the genus Asterope by G. W. Müller. I have myself had an opportunitv
of investigating the type-specimen of this species.* Unfortunately there was only the shell
of this specimen and the distal part of one cleaning limb, whieh I discovered inside the shell. These
organs were not sufficient to enable me to classify the species with complete certaintv. I can
however say that it does not belong to the genus Asterope in the sense in whieh this genus is
taken in the present work. It will presumably be necessarv to set up a new genus for it. The
shell, which it is, as a matter of faet, absolutely necessarv to describe again, indicated a close
relationship to Cyclasterope-, the cleaning limb was of about the same type as that of Cycloleberis.
Besides these two species two forms placed by G. W. MÜLLER under the heading
„Cypri-dinidarum genera dubia et species dubiae“ also come into this c jit egory. These are:
Cyclasterope similis, G. S. Brady, 1902 a, p. 183, pl. XXIII, figs. 25—29.
Asterope squamiger, T. SCOTT, 1894, p. 140, pl. XIV, figs. 56, 57, pl. XV. figs. 14. 22, 23, 26.
