As the Ortyx Virginiana is now included in the British 

 Fauna, I considered its parasite ought to find a place in this 

 monograph, and for the opportunity of figuring it I am 

 indebted to Abraham Clapham, Esq. who supplied me with 

 specimens obtained from some of these birds which he im- 

 ported from America, for the purpose of turning loose on a 

 manor near Selby. Although this species resembles in 

 some respects G. Colchici and Tetraonis, it is readily dis- 

 tinguished by its more slender form and smaller size, as well 

 as the general colour of its several parts.
