Report on the Crustacea Schizopodu of Ireland. 220 
appear in the collection. ‘The bulk of the survey material was taken in bags of 
mosquito-netting suspended inside the large beam trawl. This is, apparently, 
a most efficacious method of collecting Schizopods, but has the disadvantage of 
injuring the specimens on account of the strain against the meshes resulting from 
the comparatively high speed at which the trawl is hauled, and the frequent irrup- 
tion of large fish, crabs, sand, and other injurious matters. Mosquito-netting is, 
moreover, rather coarse for such small creatures as Evythrops elegans, &e., and this 
must be borne in mind in considering the evidence afforded by our record of the 
numbers of different species taken in the several hauls. 
In the systematic list it will be understood that we adopt Norman’s classifica- 
tion and synonymy, unless the contrary is expressly stated. Further, in the brief 
account which we have given of the distribution, it has seemed to us desirable to 
condense the references by ascribing to Norman (A. M. N.*) those records, whether 
original or compiled, which appear in his paper. In some cases we have condensed 
the record still further, as by substituting ‘“‘ HE. and W. Scotland” for various 
localities on both coasts. Professor Sars’ work is too well known to need mention 
here ; while Norman has himself ackowledged the assistance of Mr. Thomas Scottt 
and others in the communication of British forms. The most important paper, 
after Norman’s, dealing with Irish Schizopoda, is that of Mr. A. O. Walker.{ 
Records other than Irish, which have appeared subsequent to Canon Norman’s, are 
indicated by the author’s name or initials. Mr. Walker’s records from the Irish Sea, 
which are of importance on account of the propinquity of the localities to the [nish 
area and of the absence of any records from the adjacent parts of the Irish coast, 
are to be found in the Transactions of the Liverpool Biological Society. Where a 
locality is followed by a colon or full stop without the citation of an authority, it 
must be taken that we are ourselves responsible, while a note of exclamation 
indicates the confirmation by ourselves of the record of a previous observer.
