Explanation of Plates. 



The figures used for illustration were to have been made from the speeimens used for the descriptions, 



but as those speeimens had been more or less injured by repeated handling, other speeimens were specially 



prepared for the drawings. The figures will accordingly be found to differ from the descriptions in certain 

 minor details.
