were in several respects closely related to the genus Cypridina, in otliers to Asterope. „From
this mixture of the characters of the two genera, and taking into considération the minuteness
of the parts examined, and the different appearance these same parts assume in different
positions under different microscopes and with different observere, I am inclined to believe
these two genera to be identical.“ In his work of 1850 a W. BâIRD says, p. 176, that he is
following the authority of J. D. Dana in synonymizing these two genera; he writes: ,,fide
Dana in literis“.* Finally F. Müller also uses the generic naine Cypridina for species
bel on gin g here in his essay ,,B emerk ungen über Cypridina“, 1870, a work whieh is
to sonie extent rather meritorious and which is based on the dissection of three C y p r i d i n i d s
(one species belonging to the genus Philomedes and two species belonging to the family
Astero-pidae). This author writes on p. 255: „Ich behalte für alle drei, wie überhaupt für alle
Muschelkrebse, die seitliche Augen und die bekannten „geringelten Anhänge“ besitzen, den Namen
Cypridina bei.“ F. Müller explains this point of view by stating that the anatomy of all
the species then described was too inadequately known to permit of a scientifically founded
division of the forms belonging to this unit into smaller systematic units.
G. 0. Sars, in his work of 1865, p. 100, points out that Asterope must be considered
as a special genus, well distinguished from other Cypridinid s.
G. S. BRADA, in his work 1868 a, p. 127, established a new genus C y lindr oleberis, which
included two species previously grouped under the genus Cypridina, G. Mariae W. Baird and
C. teres A. M. NORMAN. Brada did not, however, retain this new generic name long; already
in his work of 1871 he identifies (p. 292) the genus Cylindroleberis with Asterope PHILIPPI and in
all his subséquent works we only find the latter name. In spite of this a number of investigators
who afterwards dealt with forms belonging to this unit have nevertheless retained the name
C ylindr oleberis, thus, for instance, G. W. MÜLLER in his works of 1893, 1894, 1906 b and 1908
(not 1890, where he uses the generic name Asterope), J. A. Clshman, 1906, Ch. Juday, 1907,
R. W. Sharpe, 1909 and Tu. Stebbing, 1910. The reason for this is to be fourni in the faet
that in the same year (at the same time?) as A. Philippi pu blished his essay on the genus
Asterope two other investigators (Müller and TROSCHEL) described a new Echinoderm genus
under the same name. As, however, according to modern nomenclature, the generic name
Asterope cannot be used for the Echinoderm genus established by the two latter authors, this
difficulty may be considered to have disappeared. Accordingly in the present work I considered
it convenient to follow G. S. Bhada’s example — as G. IV. MULLER did in 1912 — and use the
name given by A. Philippi for this genus.
The genus Copechaete, E. Hesse, 1878 may be brie fly dealt with here. This genus was
identified by G. O. Sars, 1887, p. 13 with the genus Asterope Philippi: „At den af Hesse under
Benaevnelsen Copechaete opførte Slaegt er identisk med Asterope, er utvivlsomt“.** G. S. BRADA
and A. M. Norman, 1896, adopt this name as „undoubtedly“ synonymous with Asterope, „but
what his species are it is impossible to say“. G. W. Müller goes still farther; in 1912, pp. 45
* .1. I). Dana himsolf writes, 1852. p. 1290, about Ihr genus Cypridina: ..II appears lo include Ihr Asterope of
Philippi.“
** ..li is certain Ihal Ihr genus eslablishrd by Messe under Ihr name of Copechaete is idontiral wilh Asterope.“
