sent the following. Many of them are common, but perhaps not the less interesting 

 to those who are fond of the study of Nature, and whose attention may not have been 

 hitherto called to this much neglected branch oi Natural History, and which especially 

 deserves the notice of entomologists, who, when in quest of insects, may also make 

 shells a subject of their pursuit. Thus, a collector, while examining the oak {Quercus 

 Robur) for insects, may take the beautiful little Helix aculeata, usually found on the 

 trunks ; this species may also be found under decayed wood. The hedges, lichens, 

 mosses, fences, trunks and roots of trees, will not unfrequently furnish a variety of spe- 

 cies. The young conchologist will be amply repaid by a visit to the British Museum, 

 where he will find an extensive and admirably arranged collection in this department 

 of science. Mr. Gray's edition of Dr. Turlon's excellent ' Manual of Land and Fresh- 

 water Shells ' contains much valuable information on this subject; indeed, no student 

 in this branch of Natural History should be without it. I might also name the admi- 

 rable observations of Mr. Bridgman, of Norwich (Zool. 2741), which are well worth 

 reading, besides localities where a great many species may be met with. Without 

 trespassing further on your valuable journal, I proceed to give the list. 



Bithinia tentaculata. Ditches, common. 



Valvata piscinalis. Streams and ponds, uncommon. 



Helix aspersa. In gardens, very common. 



hortensis. Hedges, common. 



nemoralis. In similar situations, common. 



scantiana. Hedges, common. 



arbustorum. Marshy places, common. 



rufescens. Under stones and on old walls, common. 



Succinea putris. Marshy places and in streams on aquatic plants, uncommon. 



amphibia. Marshy places, common. 



Zua lubrica. Under moss and stones, uncommon. 

 Azeca indens. One specimen under moss, rare. 

 Balaea perversa. Old walls, rare. 



Lymneus palustris. Streams, rare. 



Physa fontinalis. Streams, on aquatic plants. 



Planorbis cornea. Ponds and streams, common. 



carinatus. In similar situations, uncommon. 



vortex. In similar situations, not common. 



Cyclas cornea. Streams, common. 



I have no doubt many more might be added to the above list, if the river were 

 examined. Fulham is not a good locality, in consequence of the absence of woods. —

Evening Meeting, March 25, 1851.— W. Yarrell, Esq., V. P., in the chair. 



Mr. Gray called the attention of the meeting to two species of the genus Herpes- 



tes, new to the Fauna of Ceylon, which had been collected there by Mr. Grace, and 



transmitted by him in a living state to the menagerie. Mr. Lewis Llewellyn Dillwyn 



read a paper on the habits of an undescribed species of Megapodius, as observed by
