BLACK-BELLIED DIPPER. 67 



The Black-bellied Dipper is a common Scandinavian and 

 North Russian bird, and seems occasionally to wander across 

 the waters of the North Sea to eastern England. In our own 

 county it has hitherto only, and perhaps, obviously, been 

 obtained in the vicinity of the coast, where in the East Riding 

 it has been obtained on four occasions ; twice during the period 

 of the autumn migration. Three of these birds have passed into 

 the hands of ornithologists and, it is worthy of note, have been 

 examined by experts and pronounced to be true vielanogasteres. 

 The following are the particulars of the occurrences : — 



One shot on a drain at Welwick, on the 24th of October 

 1874, is now in the writer's collection. 



In the Zoologist (1876, p. 4871) Mr. F. Boyes records as 

 a Black-bellied Dipper one shot on the river Hull at Beverley, 

 on the 29th of October 1875, by a man named Priestman. 



The Rev. Julian G. Tuck (Field, Jan. 1876, p. 22) men- 

 tions one shot at Flotmanby near Filey, on the 8th of Decem- 

 ber, 1875. 



In the collection of Mr. J. H. Gurney, Jun., is a specimen 

 which was shot near Bridlington, and was purchased by him of 

 the late Mr. Jones, taxidermist, of Bridlington Quay. 



Another East Riding Dipper was shot by the Rev. F. O. 

 Morris in the stream at Nunburnholme on the loth of January 

 1856, but as this specimen was not preserved further informa- 

 tion regarding it cannot now be obtained.
