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



Genus Scottia, Brady & Norman. 



Scottia Browniana (T. R. Jones). 



The habitat on the shores of Loch Fadd, in the Isle of Bute, where this species 

 was found by Mr. T. Scott, is so remarkable, that it is worthy of further notice. 

 It was visited by A. M. N. in company with Mr. D. Robertson, who knew the 

 spot. A spring rises on a bank close to the loch, into which the water finds its 

 way among the grass ; the water is nowhere trickling more than two or three 

 inches deep among the herbage. Here, amidst multitudes of Difflugiai, Scottia 

 Brotvniana lives, with Ilyodromus Robertsoni, Ilcrpctocypris reptans and tumefacta, 

 Cypridopsis Newtoni, Candona Candida^ and Candonopsis Kingsleii as its companions. 



Genus Cypeis. 



Until quite lately males in this genus were unknown ; and up to the present 

 time no male has been found in the British islands. 



In 1889 Professor G. 0. Sars, in his Paper "On some Freshwater Ostracoda 

 and Copepoda raised from dried Australian Mud " (Christ. Videns-Selks. Forhand.), 

 described more fully the genus Cyprinotus, Brady, to which he assigned the British 

 forms Cypris salina, Brady, and Cypris fretensis, Brady, and gave as one of the 

 leading characters the fact that he had raised males of Cyprinotus dentato-margi- 

 natns, Baird, from the Australian mud. "Moreover," he wrote, "there is a 

 feature that would seem to separate this genus," i.e. Cyprinotus, " very markedly 

 from the genus Cypris (sens, strict.), and to bring it in closer relationship with the 

 genus Cyprois of Zenker ; as with the latter genus the propagation is sexual, and 

 not as in the true genus Cypris exclusively partlienogetical, the males being 

 almost as frequent as the females." 



It is true that Dr. S. Fischer, as long ago as 1855 {Beitrag sur Kenntniss der 

 Ostracoden), had recorded males in his Cypris prasina, Cypris exserta, Cypris 

 rivularis, and Cypris mareotica, but the first would seem to be referable to Sars' 

 genus Cypritiotus, the second is perhaps a Candona, the third also probably a Candona, 

 the last doubtful, until now identified by Moniez as a true Cypris. More recently 

 Professor C. L. Herrick ("Freshwater and Marine Crustacea of Alabama," Mem. 

 Denison, Sci. Assoc, vol. i., 1887), states that he had found in Alabama males of 

 a Cypris which he refers to C. virens, and of a species described by him as 

 C. modesta. It remained, however, for M. R. Moniez finally to clear up all doubt 

 on this matter. In two Papers published in 1891,* he records the occurrence of 



* " Les Males ohez les Ostracod.es d'eau douce " (Eevue Biol, du Nord. de la France), and " Fauue dus 

 Lues sales d'Algierie " (Mum. do la Soc. Zool. de France).
