chestnut-red, while some shells, especially when wet, make no 

 very distant approach to scarlet. This variety and the var. 

 hybrida — which also occurs here — appear to pass into each other 

 by insensible gradations. The form possessing colourless bands 

 is far from uncommon ; some have the bands coloured for a small 

 part of their length. 



H. arbustorum. — Numerous in low ground close to the town ; 

 of good average size, and both with and without the band. 



H. cantiana. — The commonest roadside snail, except after 

 heavy rains, when II. hortensis exceeds it in numbers. Many 

 specimens might, I think, be referred to the var. rubescens. 



H. rufescens. — Common near Much Hadham and Widford. 



II. concinna. — Common. 



H. hispida. — Noticed several examples on hedge-banks. 



H. virgata. — Not observed in the immediate neighbourhood 

 of Hadham, but near the curious old town of Hatfield Broad Oak, 

 a few miles over the Essex border, it was fairly common by the 

 roadside. 



II. ericetorum. — Only noticed in one spot — a grassy bank by 

 the side of the road leading from Much Hadham to Bishop's 

 Stortford. It seemed to be fairly numerous, but confined 

 apparently to a very small area. 



Cyclostoma elegans. — Occurs on a few steep banks, almost 

 within the town of Much Hadham. 



The genus Zonites seems to be well represented, being 

 especially abundant at the bottom of the deep dry ditches, 

 thickly overgrown with bushes, which border some of the lanes 

 and by-roads, and form a pleasing feature in the landscape ; but 

 of this and various other genera, comprising the smaller snails, 

 such as Pupa, Vertigo, Clausilia, &c, I can say nothing, having 

 had no time to devote to them. 



Avion ater can hardly be passed over without notice, as it is 

 here very abundant. Every specimen met with was of an intense 

 black. 



Succinea elegans occurs about the margin of ponds in the 

 neighbourhood. 



Of water snails, I only saw Byth'uiia tentaculata, Physa 

 fontinalis, Limncea peregra, L. stagnalis, and L. truncatula ; but 

 no doubt a careful search would reveal many more species both 

 of land and water shells.
