NOTE. 



The number of the Genera of Fishes at present recorded in 

 the British Fauna, amounting to 124, it naturally suggested 

 itself, that by pourtraying two fishes on each of the 68 Plates 

 of our two Volumes, one Specimen at least of every Genus 

 might he presented for the examination of the Header. We 

 mention these details as the shortest explanation of the dis- 

 crepancy which ivill be found between the references to the 

 Plates in the Letter-press of this Volume and the Plates it 

 contains. They are chiefly in the ivay of omission, several 

 fishes being stated to be exhibited which it was found impos- 

 sible to introduce. The Reader, accordingly, will have the 

 kindness to tahe as his guide for the Plates, not so much 

 the Letter-press, as the following Contents, which contain 

 a correct List of those it has been found practicable to 

 introduce.
