NOTES ON ENTOMOSTKACA. By G. S. Brady, M.D., F.R.S., 

 F.L.S., with Plate- XIX. 



The Entomostraca here referred to are only the more interesting and 

 scarcer species from gatherings which have been sent to me at various 

 times by Mr Thomas Scott. Though, as is well known, Entomostraca of 

 various kinds constitute a large part of the food of fishes, it is probable 

 that the Ostracoda — and especially the marine Ostracoda — are less im- 

 portant in this respect than the softer kinds, Copepoda and Cladocera, 

 which, owing to their immense fecundity, occur in prodigious numbers, 

 and on account of their free-swimming habits fall an easy prey to fishes. 



OSTRACODA. 



Cypris cinerea, Brady. Pools near high water, head of West Loch Tarbert. 

 Cypris tumefacta, Brady. Tarbert, Loch Fyne. 



Cypris virens var. monilifera, Brady. Ditches near Loch Ascog and 



Loch Fadd. 

 Cypris, Jurinei, Zaddach 1 



Cypris Browniana, Jones. Pools by the side of Loch Fadd. 

 Canclona Kingsleii, Brady and Robertson. Pools near Loch Fadd and 

 Loch Ascog. 



Potamocypris fulva, Brady. Marshy place by the side of Loch Ascog. 

 Aglaia complanatal Brady and Robertson. East Tarbert ; one specimen. 

 Cythere semipunctata, Brady. Loch Fyne, near Tarbert ; not uncommon. 

 Cythere Clutkce, Brady, Crosskey, and Robertson. Loch Fyne, near Tar- 

 bert ; scarce. 



Cytheridea subflavescens, Brady. Loch Fyne, near Tarbert; not uncommon. 

 Cytheropteron angtdatum, Brady and Robertson. Rothesay Bay and East 



Loch Tarbert. 

 Cyllierideis subidata, Brady. Rothesay Bay. 

 Paradoxostoma obliquum, G. O. Sars. Rothesay Bay. 

 Asterope teres, Norman. East Loch Tarbert ; not very common. 



COPEPODA. 



Peltidium purpureum, Philippi. East Loch Tarbert, 3 to 4 fathoms ; not 

 common. 



PELTIDIUM PURPUREUM, Philippi. 



Up to the present time we have no published information of the occur- 

 rence of this species in the British seas. Its occurrence in the Loch Fyne 

 dredgings of the Fishery Board is therefore specially interesting, inas- 

 much as we are now in a position to define accurately the genus Peltidium 

 from an examination of the species to which the name was originally 

 applied. The little creature appears to be very scarce, Mr T. Scott
