220 The Irish Naturalist. November, 



At the second meeting Prof. Grenville Cole presided. The 

 attendance at the opening was good, but became thin as the 

 afternoon passed awa}^ — perhaps through the attraction of the 

 part}' at the Zoological Gardens. Several papers of interest 

 were read and discussed. 



THE SURVEY OF RESTRICTED AREAS WITH REGARD 

 TO THEIR FLORA AND FAUNA. 



BY PROF. GEO. H. CARPENTER. 



The writer gave a short account of what had been done, and what was 

 proposed to be done in Ireland, to impress upon all interested in the 

 work of local societies the important results that might be obtained 

 from the really systematic survey of restricted areas with regard to Flora 

 and Fauna, atid their relations to the country in its wider aspects. 

 Lambay had been surveyed with considerable care during the last 

 few years. The results were surprisingly good. They found five animals 

 new to science, twelve new to the Britannic Fauna, and eighty animals 

 and plants new to the Irish Fauna and Flora. One of the principal 

 objects of this survey was to trace the paths of migration of animals and 

 plants along the east coast of Ireland. A survey is now being conducted 

 by the Dublin Naturalists' Field Club of the North Bull, a sandbank 

 known from the evidence of old maps to be only a century old, the 

 object of the survey is to ascertain what species first occupy new portions 

 of land. A survey of Clare Island is about to be conducted, and very 

 important results are hoped to follow from such a research on the west 

 coast where the Fauna and Flora are of exceptional interest. In con- 

 clusion, the writer trusted that his remarks would have the effect of 

 directing the efforts of local societies to the desirability of having such 

 surveys in Great Britain as complete as possible. 



THE ADVIS'^BIIvITY OF RE-vSTOCKING HAUNTS FROM WHICH 

 RARE SPECIES HAVE DISAPPEARED. 



BY H. DAVEY (BRIGHTON). 



In this paper the writer gave evidence for the view that extinction of 

 many rare species has not always followed as the result of over-collect- 

 ing, but frequently from climatic or other uncertain cause. For 

 example, the Large Copper Butterfly was, doubtless, exterminated by 

 collectors in some of its haunts, but not in all. Attention was also called 

 to the unaccountable restriction of many insects to small areas, and 

 I heir total absence from exactly similar, or apparently equally suitable 

 places in the neighbourhood. The judicious introduction of fresh 

 broods of extinct or vanishing species was advocated. 



In the discussion that followed, the importance of recording all 

 artificial introductions was strongly urged by several members.
