OSTRACODA. 



Although no collection of Ostracoda from the Survey has been worked 

 out, yet a considerable number of marine species has been recorded from the 

 Clare Island district. These records have been extracted from the paper 

 by Canon Norman on " Irish Crustacea Ostracoda," published in the " Irish 

 Naturalist" (vol. xiv). They are due mainly to Brady and Eobertson or to 

 Canon Norman himself. The names of the recorded species are given below; 

 and for details reference should be made to the paper in question.
