MITCHILL ON THE FISHES OF NEW-YORK. 359 



ton's English translation; and the ichthyological part of Shaw's General 

 Zoology, as published in London. 



From the latter of these works I have copied the generic characters 

 which illustrate the species that I have described. 



I need scarcely mention, that the splendid works of Catesby and 

 Edwards have been constantly at my elbow. 



I feel a peculiar pleasure in stating my, obligations to the labours of 

 my assiduous and excellent friends, Samuel Akerly and Samuel G. 

 Mott, of the city of New-York, physicians. The former of these gen- 

 tlemen drew from nature most of the figures which accompany this 

 memoir; and the latter, by his activity and vigilance, detected many 

 of the individuals, which, without his aid, might not have come to my 

 knowledge. I owe them much for the drawings and specimens with 

 which they have supplied me. Science will never cease to respect 

 them both. 



To James Inderwick, Esq. I also am indebted for several graphical 

 representations. To his skill in delineation, and to his cultivatd 

 mindj I am highly gratified in bearing testimony.
