Asterope teres, G. S. Bhaüy and A.M.NORMAN, 1896, p. 636, pl.L, figs. 7-10.pl. LII. figs. 20,21.
Type species: Asterope elliptica A. PHILIPPI, cf. below.
Divergences from the genus Asterope, G. \V. Müller, 1912:
The following species are included in this genus by this author, but are excluded by me:
Cypridina Adamsi, W. Baird, 1847.
Asterope Arthuri, T. Sterling, 1900.
Cyclasterope fascigera, G. S. Brady, 1902 a.
,, Hendersoni, G. S. Brady. 1897.
Asterope Hilgendorfi, G. W. Müller, 1890.
,, lichenoides, G. S. BRADY, 1902 a.
Species which,fccontrary to G. \\. MÜLLER, I include in this genus:
Cypris bimaculata, H. NlCOLET, 1849.
Cypridina nitidula, Fr. Müller, 1870.
The two last-mentioned species are put by G. \V. MÜLLER under the heading:
„Cypri-dinidarum genera dubia et species dubiae.“ In spite of the incompleteness of the original
description, there can scarcely be any doubt that Cypridina nitidula really belongs to Asterope
in the sense that this genus has been taken in the present work. (This form is placed together
with the forms in this group by G. W. MÜLLER, 1894.) But C. bimaculata is doubtful.
Everything indicates, however, that this species too belongs to this unit.
Genus Cyclasterope: —
For description see below.
For reasons that are best seen in the historica! resumé given above pp. 438, 439 itseemedto
me necessary to give this genus rpiite another scope than G. W. MÜLLER had given it in 1912.
Besides the species C. fascigera, re-described by me below, the following species are
probably to be included in this genus:
Cyclasterope Hendersoni, G. S. BRADY, 1897, p. 86, pl. XV, figs. 1—12.
Asterope Hilgendorfi, G. XV. Müller, 1890, p. 241. pl. XXV, fig. 15, pl. XX\ I, figs. 8. 20,
pl. XXVII, figs. 4—6, 17.
Nor does it seem impossible to me that Asterope Arthuri, T. Stebbi.ng, 1900, p. 660.
pl. LXXII, A should be included in this genus, but the position of this species is somewhat
uncertain. (It is described from a male larva.)
Type species: Cyclasterope Hendersoni, cf. p. 438 above.
It was necessary to set up two new genera. These have been given the names Cycloleberis
and Asteropteron.
Genus Cycloleberis:* —
Diagnosis: — The shell, seen from the side. is rounded and has no decided
posterior corner and no decided sculpture.
Second antenna: Exopodite: The natatory bristles have a strong equipment
of spines; the basal spines are very powerful. Endopodite: This has rather numcroUs bristles
on the first joint.
* Fro:ii y.vy./.oç; = cycle and /.eßi/ot* = shell.
