660 ON CRUSTACEA BROUGHT BY DR WILLEY FROM THE SOUTH SEAS. 



In 1865 G. O. Sars divided the Ostracoda into four sections, Podocopa, Myodo- 

 copa, Cladocopa, Platycopa. In 1896 this classification is retained by Brady and 

 Norman. In the meantime G. W. MUUer had reduced the four sections to two tribes, 

 the Myodocopa and the Podocopa, the former including the Polycopidae, the single 

 family of the Cladocopa, and the latter including the Cytherellidae, the single family 

 which had constituted the Platycopa. 



Fam. Asteropidae.

The genus for which this family was instituted is included by G. W. Mliller in 

 the Cypridinidae. But, as Brady and Norman say, " the family is widely separated 

 from other Myodocopa by the peculiar structure of the three pairs of maxillae, and 

 the presence of dorsal branchiae." They begin their account of the family with the 

 character, " shell more or less oblong or elliptical," which well suits some of the 

 species, but is not very apijlicable to the nearly circular shell of CylindroleheHs 

 Lobianci, Mliller. Whether the family name should be Asteropidae or Cylindroleberidae 

 depends on the validity or the reverse of the generic name Asterope.

In 1840 the name Asterope was given to a genus of Echinodermata, which in 

 the same year received independently a different name. But whether the ostracode 

 was named Asterope by Philippi before the starfish was so named by Muller and 

 Troschel remains obscure. Since the late Mr Bladen in his Challenger report re- 

 linquished the claim to the title Asterope for the starfish, and Dr Brady has relinquished 

 his own claim to the title Cylindroleheris for the ostracode, it can scarcely be wrong 

 for the present to follow Brady and Norman in adopting Philippi's generic name.
