A UST OF IRISH OSTRACODA 

 Compii,e:d from Brady and Norman's Catai^ogue- 



BY R. F. SCHARFF, PH.D. 



The only paper ever published exclusively on Irish Ostracod 

 Crustaceans is one on the species observed in Belfast lyough by 

 the late Dr. Malcomson {Proc. Belfast Nat. Field Club, 1884-5). 

 No separate complete list of the Irish Ostracoda has appeared 

 in print, and I venture therefore to present one to the readers 

 of the Irish Natuj'alist, in the hope that the study of this 

 interesting group of animals may thereby be facilitated. 

 Anyone in Ireland who wishes to investigate Ostracods can 

 thus at a glance see what species have been recorded from the 

 inland waters or the sea surrounding this country.^ 



The list of the species as here given has been compiled 

 from Brady and Norman's " Monograph of the Marine and 

 Freshwater Ostracoda of the North Atlantic and of North- 

 western Europe." This very important and excellent work 

 was communicated to the Royal Dublin Society by Prof. 

 Haddon and was published in the Transactions of the Society . 

 The first part appeared in 1889, and it was completed in 1896. 

 Figures of most of the species are given by the authors, and 

 many descriptions of new species appear here for the first time. 

 There are altogether 27 freshwater and 120 marine species. 



I have marked with an asterisk i^) those species which have 

 never been found elsewhere except in Ireland or the sur- 

 rounding seas.

' I hope shortly to publish a map indicating the boundaries of the 

 Irish Marine area, as we propose to define them in the new arrangement 

 of the Collection of Irish Marine Animals in the Dublin Museum.
