INTKODUCTOEY NOTE. 



Forty years have elapsed since the publication of a " Cornish 

 Fauna," a compendium of the Natural History of Cornwall, and 

 a convenient companion to the Museum of the Institution under 

 whose auspices it was produced. Lapse of time, and a large multi- 

 plication of observers have added much to what was then known, 

 and it is gratifying to find that the constant wish of Jonathan 

 Couch is now fulfilled in a much needed second edition of the 

 first part. With such a desire he collected largely, and even 

 went so far as to write the following preface, which was found 

 among his papers, and forwarded to the editor by his son, Mr. 

 T. Q. Couch, of Bodmin. It will be seen that Mr. Couch con- 

 templated adding to the original design, an account of such 

 extinct animals as have had comparatively late entombment in 

 our diluvial soils, gravels, drift, or cavern accumulations, and 

 this still remains a work to be done.
