PREFACE 



CTINCE the issue of Volume I. of the Systematic Lists, the 

 production of these has somewhat fallen off, and it has 

 been considered advisable by the Committee that the second 

 volume should now be compiled. 



The eight papers constituting this volume have been already 

 distributed, as Appendices to the Club's Proceedings, to members 

 in the various years of their publication. Following precedent 

 they have been paged so that they might be bound into a separate 

 volume which would be available to members joining the Club 

 since their circulation, and to the general public. 



It is hoped that further Systematic Lists dealing with the 

 Natural History of the North of Ireland will shortly be forth- 

 coming, as several members have been actively engaged in 

 collecting the necessary material for the compilation of such lists.
