On account of very unfavourable weather, the 

 attendance was small ; and as little work could be 

 undertaken, no attempt was made to compile lists 

 of the plants, etc., observed. 



The following is a tabulated list of the species 

 and varieties of Mollusca, Flowering Plants, Ferns, 

 Mosses, etc., identified at the Excursions at which 

 such observations were made. With very few 

 exceptions, the nomenclature respectively followed 

 is that of The Conchological Society's List of British 

 Land and Freshivater Mollusca (1883), The London 

 Catalogue of British Plants (8th Edition, 1886), and 

 The London Catalogue of British Mosses and Hepatics 

 (2nd Edition, 1881). 



The figures opposite the name of each species 

 or variety indicate that it was observed at the 

 excursions which bear corresponding numbers in 

 the list given on page 322. Thus, for example, 

 Helix nemoralis, L., was found at Dairy and 

 Caldwell, these excursions being respectively num- 

 bered 2 and 9 in the list on page 322. For purposes 

 of comparison, the reports of excursions within 

 each County have been rnaced side-by-side, in 

 preference to arrangement in chronological order. 



This list cannot be regarded as indicating ex- 

 haustively, or even approximate^, the number of 

 species to be found in the localities visited ; it 

 rather shows what may be observed in the course 

 of afternoon rambles in places within easy access 

 from the city. In cases where the data have 

 resulted from unaided search by the compiler alone, 

 many species and varieties have no doubt been 

 passed unnoticed which would readily have been 

 detected by a numerous party of workers. This has 

 obviously occurred in the case of several common
