OF THE 



CORNISH FAUNA, 



By JONATHAN COUCH, F.L.S., fa 



It is desirable that as each successive portion of this com- 

 pendium of the Natural History of the County is produced 

 to the public, a record shall be made in it of such species 

 of the families treated of in the former parts, as may have 

 been discovered since their publication ; or where they are 

 already known, but as of rare occurrence, that such addi- 

 tional information shall be given as may lead to a more 

 extended knowledge of them. Something like this has been 

 already attempted at the end of the second part; where the 

 new discoveries are enumerated in a report which was 

 originally read before the section on Natural History of 

 the British Association for Science, when it assembled at 

 Plymouth in the year 1841. Our additions at this time 

 therefore must be regarded in the light of a second supple-

 regard as being the last that will probably appear in any 

 close connection with the enquiries of the author of the two 

 former, be will employ the occasion now presented to him, 

 to express the pleasure he feels in knowing that observers of 

 nature in the held and flood, have within a few years so 

 greatly increased, as well in ability and accuracy, as in 

 numbers. He can well call to mind a time when that indi- 

 vidual was thought to be possessed with some great singu- 

 larity of taste, who could be prompted in rain or sunshine, 

 fair or stormy weather, to wander among the recesses of the 

 shore, to search out and examine the strangely formed 

 creatures of God in their native baunls. There was no 

 kindred spirit to hail his success, nor any accessible perio- 

 dical through which to pour out his pleasure of discovery, 

 and increase it by communication to the equally solitary
