this has shrunk, it shews hovv well the damaged portion has been 

 covered over. 



Named varieties of H. fievioralis are sometimes found in consider- 

 able quantities in restricted areas ; my friend, Mr. C. E. Wright, 

 found many specimens of the var. citrinozonata on a railway bank, 

 near Kettering, and the same variety is also found in quantity at 

 Carrickfin, in North-west Donegal. The var. oUvaceosonata, found 

 by Dr. Chaster and myself at Magilligan Strand in Derry, was con- 

 fined to a very small area of a few square yards. 



I have been fortunate enough to find a few reversed specimens, 

 including one of H. nemoralis var. libellula ooooo, at Gleninagh, near 

 Ballyvaughan, Co. Clare; and another, also libellula 12345, at Cor- 

 beyrier-sur-Aigle, Vaud, Switzerland ; both were found in old stone 

 walls. The first year that I went to Croyde Bay, walking over the 

 hill to the Putsborough end of Woolacombe Bay, the very first shell 

 that I picked up was a reversed H. caperata, dead, but in good con- 

 dition. The most interesting find, however, was a reversed Acicula 

 lineata, amongst a lot of small shells I brought home from a rain- 

 wash on Tramore Strand, North-west Donegal — only the second 

 specimen recorded from the British Isles. This rainwash was a most 

 extraordinary sight. Our party was staying at Dunfanaghy, and a day 

 or two after our arrival it began to rain heavily, and as it rained for 

 thirty-six hours every place was flooded, so much so, that the magis- 

 trate who was staying in our hotel, and who went off to the station, 

 some four miles away, to go on to (iweedore, had to return, as the 

 road was four feet deep in water. On the weather clearing up, we 

 went off to Tramore Strand, a large stretch of sand dunes, some as 

 high as 300 feet, connecting Horn Head with the mainland. Evi- 

 dently the very heavy rain had formed a small pond, some twenty 

 yards, across, and had brought down large quantities of shells, most 

 of them evidently from very old shell pockets, probably of Elolocene 

 a"e. The water had at last run away, but round the high-water mark 

 there was a deposit of hundreds of thousands of dead and broken 

 shells. Amongst the recent shells were large quantities of broken 

 and immature H. nemoralis, H. itala, and JT. barbara, but it was 

 the extraordinary quantity of the smaller species that surprised us ; 

 there were V. cryslallina, V. pura, E. fuhms, P. pyg/>iceu/ii, Sp. eden- 

 tuluin, A. aculeata and var. albida, V. pulchella, C. liibrica, P. 

 anglica and var. alba, P. cylindracea and var. albina, P. iiiuscoruiii 

 and var. albina, V. substriata, V. pygnuca, V. piisilla, V. angustior, 

 CI. bidentata, C. iniiiinium, Ovatella bidentata, and Acicula lineata. 



Some species are occasionally found in very unlikely places. IMy 

 finest and largest specimens of B. perversa are from a wall bounding
