THE CONCHOLOGIST, 



Byne ; and a set from Hoylake, Cheshire, 

 taken by Mr. J- Ray Hardy. Mr. Thomas 

 Rogers showed some curious examples of 

 normally sinistral species of foreign land and 

 aquatic shells of considerable interest. 



July 6t/i. — Mr. Edward Collier in the chair. 



Mr. Standen, the Honorary Secretary, read 

 a report of the Society's excursion to Lostock 

 Gralam, on June 20th, giving details of the 

 Mollusca observed. The party were under 

 tlie leadership of Mr. J. Grafton Milne, and 

 liad a pleasant ramble round by Budworth 

 to Marston Forge. The ponds along the 

 route were found to be very barren in 

 molluscan life, the mud being so foul that 

 no Invalve shells could exist, and only one 

 species, SpJueriuin laciisfre, was taken during 

 the day. Limncp.a anricnlaria and Plaiiorbis 

 )iiiidus were the most notable captures in fresh- 

 water species. A wood at Marston proved 

 to be the best hunting - ground, where 

 Zotiites fiitidt/s, Z. fulviis, Sitccinea piitris, and 

 an albino specimen of Helix rottindata were 

 found. Altogether twenty-six species were 

 collected, a somewhat meagre list for what 

 seemed rather a promising locality, but it 

 was the general opinion that the close 

 proximity of Northwich, and consequent 

 smoky deposits upon the herbage, probably 

 accounted for the scarcity of the land shells, 

 as is the case in the district around Man- 

 chester. Mr. Standen exhibited some of tlie 

 shells taken during the excursion, and also 

 some specimens of Helix elegans from Dover. 

 This pretty little continental species has 

 apparently become acclimatized there, and 

 there is a flourishing colony in one locality, 

 but there is a strong belief that it has 

 purposely been introduced by some unknown 

 naturalist. 



Mr. R. Cairns showed some albino Plan- 

 orbis contorlus, and specimens of Planorbis 

 nitidus recently taken at Marple, wiiich are 



additions to the previous lists of species 

 from that locality. 



Mr. W. Moss showed Helix virgala var. 

 picla, and Valvata pisciiialis var. albida, 

 from Lewes, Sussex ; and some extremely 

 pretty varieties of Helix nemoralis and Helix 

 j arbusioruin, from Dovedale, Derbyshire. 



Mr. Charles Oldham exhibited some fine 

 Pisidiiini pussiliuii from Penistone, and 

 Pisidiuiu roseii/N, nilidin/i, and foiitiiiale, 

 from several localities about Rhos, Neigir, 

 Anglesea. 



Mr. Edward ColHer showed some varieties 

 of Helix at'biistoi ii/ii and Trocatella regiina, 

 from Cuba ; Caracolla pati/ia, from Jamaica ; 

 and Physa scalaris, from Lake Apopka, 

 Florida, whicli is a singular shell, being a 

 connecting link between the widely dissimilar 

 genera of Physa and Planorbis, and excited 

 much interest and comment, as it was quite 

 new to all present. 



Mr. Henry Hyde showed some mounted 

 specimens which he recommended as being 

 useful for class teaching purposes. — Manchesier

Mr. Edgar A. Smith described a large 

 collection of Marine Shells from Aden, and

 Fauna of the Red Sea antl their relationship 

 with that of the Mediterranean. Some new 

 species of shells, based on examples obtained 

 during the " Challenger " Expedition were 

 also described by Mr. Smith.
