I WISH it had been in my power to have 

 given a perfedl conclufion to the Zoolo- 

 gy of our country: but my fmall acquaint- 

 ance with Insects, and the fourth divifion 

 of the Vlth clafs, Lithophyta and Zoopbyta, 

 forbad me to meddle with them. The Public 

 has little reafon to regret this omiffion, lince 

 the univerfal genius John Reinhold For- 

 ster, has hinted * a delign of undertaking 

 the firft; and my late worthy friend Mr. 

 Ellis, (whom Linnaeus fo juftly ftiles 

 LynceusJ has in a great meafure executed the 

 laft. 



In my arrangement of the prefent work, 

 I have taken the liberty of making a diftind 

 clafsof the Crustaceous Animals ; and 

 feparated them from Insects, among which 

 they are ufually placed.
