one exception all the former obtained, numbering about thirty, were 

 flesh-coloured. 



Though both the above varieties of H. nemoralis were so common, 

 yet the type shell was not observed. The circumstance of H. nemo- 

 ralis being absent, and the variety hybrida occurring, strengthens our 

 opinion as to what we consider the latter to be, viz., simply a variety 

 of Jiortensis. 



We were surprised, on reaching home, to learn from the Doncaster 

 circular of the Union meeting that variations in form and colour of 

 Helix nemoralis were quite overlooked by local collectors — a speciality 

 of this ever-varying shell being made, to our certain knowledge, by 

 many Yorkshire conchologists. 



Other shells taken in and around Masham were — Pupa umbilicata, 

 C. luhrica, H. hispida, H. Jiispida var. albida, Helix rnfescens, Z. cellarius, 

 Z. alliarius, Z. cellarius, var, alba, Z. nitidulus, and Helix rotundata. 



In coleoptera we took C. polita, Hyhrvis tiliginosiis, L., Tel. lividus, 

 Pi/roc/iroa rubens, Fab., Stomis p?mticatus, Panz., Ancliomenus albipes, 

 Fab., Leistiis ferrugineus, L., and L. rufescem. Fab. 



At Ellington, about two-and-a-half miles from Masham, Helix 

 lapicida^ C. riigosa, C. hibrica, P. umbilicata, and Helix liortensis were 

 taken ; and at Ellingstring, about five miles distant, Sphcerium 

 lacustre. 



From Masham we made our way home, after having spent a very 

 pleasant and profitable holiday, fully satisfied that we had done 

 something at least towards the extension of the Natural History of 

 our county. We find that Clivina fossor is pretty well distributed, 

 and that many of the coleoptera common in the Leeds district occur 

 equally plentifully in the tract of country we have traversed. In 

 conchology we claim to be the first recorders of Bulimus obscurus var. 

 alba in Yorkshire.

Exorista hortulana, Mgn. — In the July number of the Naturalist I 

 described a male of this fly which was bred by Mr. Porritt from a larva 

 of Acronycta alni. Having lately had the pleasure of receiving from Mr. 

 Mosley a second specimen of this insect (bred from the same larva), which 

 fortunately was a female, I am now enabled to complete the description of 

 the species. I am especially glad to do this, as the female was unknown
