728 Brady and Norman — Monograph of the Marine and Freshwater Ostracoda 



In this form the shell is not only transversely bisulcated, but also tuberculated 

 (see Brady, 1868, fig, 24. Kertesz, figs. 1, 2 represent a more than commonly 

 tuberculated form), and the antennae have the antepenultimate joint furnished 

 with a long brush of setae whicli extend beyond the terminal claws (see Brady, 

 1868, PI. XXXVI., figs. 2, 6, and Brady & Norman, PI. xxii., fig. 1). 



It is the form figured by T. R. Jones in "Tertiary Entom.," 1856, PI. i., 

 fig. 3«, as Cypris gibba; by Fischer, "Das Genus Cypris," PI. v., figs. 5-8, as 

 Cypris Mplicata ; and by Brady, Crosskey, and Robertson, " Mon. Post-Tertiary 

 Entomostraca," as C. gibha, PI. xv., figs. 5, 6.

Ilyocypris Bradii is distinguished from /. gibba by the characters — 1st, that the 

 shell, though similarly bisulcated transversely, is not tuberculated ; and 2nd, that 

 the setae of the antepenultimate joint of the antennae are very short, and scarcely 

 reach the bases of the terminal spines (PL lxiii., fig. 22). 



The following synonyms appear to be referable to this form rather than to the 

 last: — 3Io7ioculus puber, Jurine (?), and 31. bistrigatus, Jurine (junior?); Cypris 

 biplicata, Koch ; C bistrigata, Zaddach ; C. sinuata, Fischer ; and C. bistrigata, 

 Lilljeborg. It appears to us to be unquestionably C. biplicata, Koch ; and that 

 name it will probably have to bear, if not one of Jm-ine's names. 



Genus Candona. 



Professor G. O. Sars has described several forms very closely allied to 

 C. pubescens, which he considers distinct. To his usual great kindness we are 

 indebted for specimens of these Candonae, and we here quote his descriptions, and 

 add illustrations from his specimens. 



Candona compressa, Koch. 

 = Candona pubescens, Brady & Norman. 

 Sars would retain Koch's two species, and attribute the name C. compressa to
