den Donu'ii ticniicn, I'olgeii." — In other words G. W. MCllicu uses Brady's name Cydasferope 

 foi- the first of flic three natural groups into which he had divided the genus Asterope in his work 

 of 1S!)4. In addition to these three species which were referred to this group in 1894 this author 

 makes the genus C yclasterope inchide four more species, Cyclasterope orbicularis, G. S. Brady, 

 1897, C. orulum and tenera, G. S. BRADY, 1898 and Cypridina zealandica, \\. Baird, 1850 b. 

 On the other hand Cyclasterope Hendersoni, the species given by G. S. Brady as the type-species, 

 is not inchided in this genus. This species is synonymized with Asterope Hilgendorfi, 

 G. W. MULLER, 1890 and is included, like Cyclasterope fascigera, G. 8. Brady, 1902 a, in tlie 

 genus Asterope, ,,sie passen zu dieser Gattung (Cyclasterope) weder nach der Schalenform, noch 

 nach dem Bau der Furca'". According to G. W. MtiLLER's view, the genus Asterope includes, 

 besides the two last-mentioned species, almost all the remaining species in this group. This 

 genus was characterized by the fact that the furca is armed with at least five almost similar, 

 slender claws, the distance between which is relatively small, ,,Zwischenraum kleiner als die 

 Dornen an der Basis breit". This author then points out that with a classification of this sort 

 there is no room for Asterope fusca, G. W. Muller, 1890. He writes, p. 33: ,,Keinen Platz 

 wlirde bei dieser Trennung finden Cylindroleheris fusca. In der Differenzirung der Furcaldornen 

 wiirde sie sich Cyclasterope, im Bau der Dornen Cylindroleheris s. str. anschlieBen. Nach dem 

 Bau der Schale ninimt sie unzweifelhaft eine ganz gesonderte Stellung in der Unterfamilie der 

 Cylindroleherinae ein; bei einer Revision derselben miiBte fiir diese Art eine besondere Gattung 

 aufgestellt werden." 



G. W. MULLER takes practically exactly the same view in arranging these forms in 

 ,,D a s T i e r r e i c h", 1912; the only exception is that Cyclasterope tenera is transferred to 

 the heading ,,Cypridinidarum genera dubia et species dubiae". Asterope fusca is referred to the 

 genus Cyclasterope. 



G. 0. Sars, 1869, p. 359 is the first to show that the genus Asterope is verv decidedly The posiiio,, of ti/,- 

 different from other C y p r i d i n i d s and that a higher systematic unit ought to be formed »'""/'" •••

from this genus, but this author does not set up any such unit. — We find a similar statement other (^i/iiniimitis. 



in G. S. Brady, 1871, p. 292, but this author does not establish a systematic unit of this sort 



either. C. Claus writes in 1876, p. 94, note 1: ,,Icli wiirde die hervorgehobenen, namentlich 



auf die Mandibeln, die beiden Maxillenpaare und den Besitz von Kiemen beziiglichen Eigen- 



thiimlichkeiten fiir vollkommen ausreichend erachten, um Asterope den Cypridina ahnlichen 



Gattungen gegeniiber als Familie der A s t e r o p i d e n zu sondern. Jene Gattungen, 



Cypridina, Monopia, Philomedes, Bradycinetus stehen einander viel naher und wiirden als 



Cypridiniden vereinigt werden konnen." — C. Ceaus is accordingly to be regarded as 



the author of this systematic unit. G. 8. Bhady and A. M. NORMAN say, however, that they 



are its authors, 1896, p. 628. — G. W. Mi'ller, 1906b and 1912, gives the Asteropids 



as a sub-family; this author divides, as we know, the sub-order Myodocopa directly into 



families: Cypridinidae, Halocypridae and Polycopidae.
