Figs. 1 and 2 were drawn by my friend Robert Etheridge, Esq., F.R.S., to illustrate papers published 

 in the ' Trans, of the Cotteswold Naturalists' Field Club ;' he has kindly allowed me to use them here ; 

 and my friend Dr. Paine, F.C.P., Hon. Secretary to the Society, has given me the use of the woodcuts. 

 To both old friends I return my best thanks.
