NORTHUMBERLAND AND DURHAM. 



Smith, Esq., M.P., Gosforth ; and R. Burdon, Esq., Castle 

 Eden, are my acknowledgements due. How very much our 

 fauna has been enriched by their liberality the catalogue and 

 revision testify. To my friends G. R. Waterhouse, Esq., E. C. 

 Rye, Esq., and Dr. Power, of London; G. R. Crotch, Esq., of 

 Cambridge, and Dr. Sharp, of Eccles, who have so kindly as- 

 sisted me with types, and in the determination of difficult spe- 

 cies, I am also under a deep sense of obligation, which I am 

 proud to acknowledge, and for which I tender them my most 

 earnest and grateful thanks.
