Pollard: A Collecting Tour in North Yorkshire. 21 



Searching at Normanby (about two-and-a-half miles from South- 

 bank), we took L. peregra in a ditch which ran through the middle of 

 a meadow. They were thickly coated with a confervoid growth. 



In coleoptera we collected G-yrinm bicolor, Payk., Laccophilus 

 ayalinus, D., Byrrhus pilula^ L., and Agriotis ^pidator. 



By a run over to the fast-rising watering-place of Saltburn we 

 were well rewarded. We took the common heart sea urchin in large 

 quantities. On the ebbing of the tide, the beach, to use an hyper- 

 bolic phrase, was covered with them. 



In mollusca we obtained the following : — Madia dultorum, Bonax 

 politum, Telina temm, T. fabttla, Trochm cinereus, Littorhia obtusata, L. 

 IMorea, Solen sili(iua, Helcion pellucida and its variety IcBvis, Cardium 

 edule, and Patella vulgata. 



In a stream of brackish water, at a few yards above high-water 

 mark, we collected very large specimens of L. peregra, covered with a 

 confervoid growth. The only land-shell taken was CocJilicopa liibrica^ 

 under old wood near the coast. 



On resuming our tour south to Mash am, a break in our journey at 

 Melmerby for almost an hour enabled us to gather Helix caniiana and 

 H. nemoralis var. Tiortemis. Arrived at Masham, we at once began our 

 work. In a pond situated about half-a-mile from the town we took 

 some of the finest specimens of Limrusa stagnalis and L. paliistris it 

 has ever been our pleasure to view ; in numbers they outstripped any 

 locality we have collected in. At one dip of the net more than once 

 eight or nine were brought up. Also from the same pond, but in 

 less quantities, were taken Plaiiorbis corueus, P. carinatm^ BytJiinia 

 tentaculata, and L. peregra. 



In the river Burn, a tributary of the Ure, Ancylus Jliwiatihis was 

 found very commonly adhering to stones. Examining a ditch a few 

 yards from the river, we discovered Succinea putris and its variety 

 sulidula, S. elegans, and Limncea truncatula^ the last-mentioned being 

 very long. L. peregra was also taken here and in three or four other 

 ditches round Masham, but varied very much in shape and appear- 

 ance in each. In one the specimens had reflected lips. Clausilia 

 riigosa was taken very profusely among moss on old and decaying 

 walls. Amongst the crevices of one, nothing but the variety dubia 

 was found. G. rugosa var. timidula was also present in several places. 



The most commonly occurring shell in this district is without doubt 

 Helix nemoralis, var. Jiortensis varying as much as plain yellow, flesh 

 colour and dark bands, often five in number could make them. The 

 varieties hybi'ida and minor of B^. ?iemoraUs were also abundant. With
