RoBEETS : List of Shells of South Milfoed. 87 



Entomologist. Also bear in mind that these calculations are based 

 upon a flock of birds seen before the passing of Bird Acts, and it is 

 only fair to assume that they have considerably increased since then 

 — perhaps doubled — and as I have gone as far as I am able in figures, 

 I leave each one to reckon the rest for himself. 



These bird laws have interfered with the balance of nature, and 

 made a blunder they cannot repair ; but I may return to this subject 

 again.

LIST OF SHELLS 

 COLLECTED OE OBSERYED ON JULY 2xd AND 9th, 



THE NEIGHBOV BROOD OF SOUTH MILFOBD. 

 By George Hoberts. 



Sphcerium laciidre. Common in the ponds about Milford Junction ; 

 some on caddis cases. Many dead and open shells were lying on a 

 dry bank, having been taken out of the water by mice or shrews. 



Pmdium nitidum. Common on caddis cases. 



Bytldnia Untaculata. 



Valvata piscinalis. Milford. 



PJiysa fontinalis. 



LimncBa peregra and L. truncatula. 

 Succinea putris. 

 Vitrina pellucida. 



Zonites nitidulus^ Z. nitidus, and Z. pums. 



Helix nemoralis. I collected altogether about 30 specimens, five, four, 

 and one-banded, the prevailing colours being various shades of red, 

 which is the colour of the soil in the district, but a few were 

 yellow. They occur generally, but few together, mostly on the 

 nettles in the hedges, and some on the top of the hedges. One 

 specimen of Nemoralk has the lip white. Near Milford I noticed 

 a snail-stone on which about half-a-dozen nemoralis had been broken 

 by a thrush. There were no fragments of Caniiana shells, though 

 the latter was abundant in the hedge close by. Amongst the few I 

 picked up there are several of the major form with depressed spire, 

 one fine trochiform specimen with one band, and one or two 

 entirely destitute of epidermis.
