The specimen from which the figure on the plate is

 Hon. Thomas De Grey, M.P., of Merton Hall, Thetford, 

 for the use of this work, two specimens having been taken 

 by himself, in 1868, and another since by his sister, the 

 Hon. Miss de Grey. I can assure them both that their 

 kindness is thoroughly appreciated.
