THE BIRDS OF DEVONSHIRE. 175 



All the foregoing occurrences took place between 

 October and April. But Mr. Gatcombe killed a 

 Great Northern Diver off the coast at Seaton, on 

 the 15tli of June^ 1861. Unfortunately, the bird

 prawns and swimming crabs. " Divers," he says, 

 "seem to feed largely on crahs^ as I have often 

 found their stomachs full of them."

 Plymouth in 1879, took occasion to remark, " I 

 have never yet seen or heard of an adult bird of 

 this species having been obtained near Plymouth," 

 adding that the most advanced specimen which he 

 had examined was a bird shot by his brother near 

 the Devil's Point many years previously. At 

 Kingsbridge, an adult bird was obtained in 

 November, 1865, by Mr. Nicholls (Zool. 1866. p.

 in different seasons. Many frequent the neighbour-
