SUPPLEMENT 
Co t$e Ctoo jFirst portions 
OF THE 
CORNISH FAUNA, 
By JONATHAN COUCH, F.L.S., fre. 
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 
a lready known, but as of rare occurrence, that such addi- 
tional information shall be given as may lead to a more 
e xtended knowledge of them. Something like this has been 
®lready attempted at the end of the second part; where the 
0e w discoveries are enumerated in a report which was 
originally read before the section on Natural History of 
'be British Association for Science, when it assembled at 
Plymouth in the year 1841. Our additions at tins time 
'berefore must be regarded in the light of a second supple- 
ment; and in adding it to that which there is reason to 
Regard as being the last that will probably appear in any 
c iose connection with the enquiries of the author ot the two 
borrner, he will employ the occasion now presented to him, 
'° express the pleasure he feels in knowing that observers ot 
® a turo in the field and flood, have within a few years so 
Sreatly increased, as well in ability and accuracy, as in 
^biuhers. He can well call to mind a time when that indi- 
'•dual was thought to be possessed with some great singu- 
a rily of taste, who could he prompted in rain or sunshine, 
a ' r or stormy weather, to wander among the recesses of the 
6 'ore, to search out and examine the strangely formed 
fixtures of God in thuir native haunts. There was no 
j'bdred spirit to hail his success, nor any accessible perio- 
lc al through which to pour out his pleasure of discovery, 
increase it by communication to the equally solitary
