 Clausilia rugosa var. dubia with Double Mouth in Wensleydale. — 



I herewith send for inspection a rather curious specimen of Clausilia rugosa var. 

 dubia found by my brother on a wall at Aysgarth on the 29th of June this year. 

 It has two mouths, one each way, and was alive when found. We also obtained 

 the following shells the same day : — Succinea ptttris, Vitrina pellucida, Zonites 

 nitidulus, Z. alliarius, Helix arbustorum, H. sericea, H. caperata, H. lapicida, 

 H. rufescens, H. rotiindata, H. ritpestris, Pupa umbilicata, Clausilia rugosa var. 

 dubia, C. laniinata, Zua lubrica, Pisidium fontinale, Neritina fluviatilis, 

 Limneea peregra, and Ancylus fluviatilis, all the water-shells being found in the 

 river Yore at Aysgarth. In more favourable weather this list might be greatly 

 augmented, as the district seems a perfect one for shells. — T. A. Lofthouse, 

 Middlesbrough, July 9th, 1889. 



[The specimen sent is a very fine example of the double-mouthed monstrosity, 

 the two mouths being well-formed. The district is — as Mr. Lofthouse says — 

 a good one for shells. The Neritina and the Pisidium he records are new records 

 for Upper Wensleydale.— W.D.R.]. 



NOTES— ORNITHOLOG Y. 

 Is the Starling Double-Brooded ? — It is hoped that all readers who can throw 

 light on this subject will favour the Editors with notes for our next (September) 

 issue. As it will materially add to the interest to publish simultaneously the 

 records of numerous observers, we hold over three notes already sent in, and we 

 trust that any who can record facts will respond to this suggestion. — Eds. Nat. 



Hooded Crows attacking and devouring Salmon. — The following 

 interesting particulars have been forwarded to me by my friend Mr. J. Farrah : — 

 Two pairs of Hooded Crows {Corvus comix) were disturbed in the act of eating 

 the body of a Salmon, weighing about 8 lbs., in the shallow waters of the river 

 Lie at Mickley. This was on December 26th, 1888. Three days later three 

 pairs of these birds were disturbed in the same act ; this time they had two Salmon 

 a little smaller than the first-mentioned, and upon examination it was found they 

 were partly eaten. The method adopted by these birds seemed to be to attack the 

 fish about the eyes, as in every case mentioned the eyes were missing ; after the 

 eyes the fleshy part of the back was eaten. All the fish were perfectly fresh, and 

 there is not the slightest doubt but that they were killed by the Crows. Anyone 

 knowing the power and rapacity of the birds will hardly be surprised at the 

 incident, especially as the fish were very much exhausted over their passage up 

 stream to spawn. Several other Salmon were captured by hand, and, of course, 

 put back again ; one weighed 14 lbs. The exact place where this incident 

 occurred is near the right bank of the stream, where it runs through the pasture 

 called the Ings. — Riley Fortune, Harrogate, June 1889.
