PROCEEDINGS OF SOCIETIES. 93 



Dr. Ball, with the view of directing attention to the manner in which animal 

 forms are represented in the different parts of the world, laid on the table specimens 

 of Ibes, from America, Australia, Asia, Africa — seven species — the species under 

 discussion being European. Amongst the specimens exhibited was a mummy of 

 the sacred Ibis, in which the gizzard still remained, enclosing the food, which in- 

 cluded amongst other things a large Paludina, swallowed on the Nile more than 

 2,000 years ago. 



Mr. Lamprey again brought under the consideration of the Association the 

 Charadrius, which had been before exhibited under the impression that it was the 

 C. minor. 



The President produced a number of species of the same bird from different 

 localities ; amongst others an authenticated specimen of C. minor, from the British 

 Museum, one of the duplicates of Hodgson's collection. This bird was much 

 smaller than the specimen in dispute, and agreed precisely with the descriptions of 

 Yarrel, Temminck, &c. Dr. Ball reiterated the opinion he had before expressed, 

 that this bird, killed by Mr. Lamprey, was only the young of the Charadrius 

 hiaticula. 



Mr. Hogan read the following — 



NOTES ON THE LAND AND FRESH-WATER MOLLUSCA OF THE COUNTY DUBLIN. 



The following notes are not intended to form a catalogue of the land and fresh- 

 water shells found near Dublin, as their form might suggest ; they merely contain 

 my own experience, which has been almost confined to a district destitute of ponds 

 or streams of uny size, or of woods that might be expected to produce rare species ; 

 besides, that I have never attempted either to collect or study the slugs. Yet that even 

 these observations may not be entirely without value, will be evident on comparing 

 a catalogue recently published (in the "Zoologist," for 1853), which, though it 

 includes seventeen species that have not fallen under my notice, does not record ten 

 that appear among those here adverted to. In the nomenclature I have followed 

 Gray's edition of Turton's M Manual of the Land and Fresh- water Shells of the 

 British Islands." 



Bithinia tentaculata. Glasnevin Botanic Gardens ; in ponds, abundant. 

 Vitrina pellucida. Mount Merrion ; scarce. 



Helix aspersa. In great abundance everywhere ; a curious variety, with the spire 

 unusually elongated, which I took at Roebuck ; was exhibited at a former 

 meeting of this Association. Some years ago I found several specimens 

 at Charlton, evidently destroyed, while in a torpid state, by a grub, which 

 was alive in the shell ; but whether it were that of a moth or a beetle 

 (instances of both of which are known) I cannot say ; the individuals 

 captured did not come to perfection. 



,, hortensis. Local ; generally on walls. 



„ hybrida. Of this species I possess a single specimen, taken by Mr. E. P. 

 Wright, while in company with me, at the Glasnevin Botanic Gardens. 



„ nemoralis. Very abundant, and with every variety in colour, as well as in 

 the number and breadth of the bands ; often without any. 



„ pulchella. A specimen at Donnybrook. 



„ hispida. Common in the usual localities. 



,, concinna. Occasionally along with the latter. 



,, depilata. Found among the two last species. 



,, rufescens. Exceedingly abundant on walls about Roebuck, and very rufous 

 usually. I have taken, on nettles, at Roebuck, a variety much more 

 carinated than usual, and also the white variety which Gray's M Turton" 

 states to be rare. 



„ Pisana. On the sea-coast at Rush, so well-marked and so plentiful, that 

 there can be no doubt of its identity, although Gray seems to distrust our 

 claim to it. 



,, virgata. Very common ; I have taken the dark brown variety, with the 

 single white band, plentifully on a wall, at Bullock Harbour, near Dalkey.
