94 THE REARING AND 



genera. This I soon found to be so considerable, that I re- 

 solved upon forming a collection, and ascertaining what was 

 written upon the parasitic tribes. 



" Goniodes stylifer (Louse of the Turkey). Common upon 

 the Turkey, frequenting the head, neck, and breast : a very 

 beautiful species. The males of this and all the other species 

 of Goniodes use the first and third joints of the antennae with 

 great facility, acting the part of a finger and thumb. 



" Goniodes dissimilis (Louse of the Domestic Fowl). I sus- 

 pect this species is of rare occurrence. 



" Lipeurusvariabilis (Louse of the Domestic Fowl). Com- 

 mon on the Domestic Fowl, preferring the primary and se- 

 condary feathers of the wings, among the webs of which they 

 move with great celerity. 



" Lipeurus polytrapezius (Louse of the Turkey). A com- 

 mon parasite upon the Turkey. Their mode of progression is 

 rather singular, as well as rapid. They slide, as it were side- 

 ways, extremely quick from one side of the fibre of a feather to 

 the other, and move equally well in a forward or retrogade di- 

 rection, which, together with their flat polished bodies, renders 

 them extremely difficult to catch or hold. I have observed 

 that where two or more genera infest one bird, they have each 

 their favourite localities ; for while the Goniodes stylifer will 

 be found on the breast and neck of the bird, the Lipeurus 

 polytrapezius will be congregated in numbers on the webs and 

 shafts of the primary wing feathers. 



" Menopon pallidum (Louse of the Domestic Fowl). Found 

 in great abundance in Poultry, running over the hands of those 

 who are plucking Fowls, and difficult to brush off, from the 

 smoothness of their bodies." Those who are desirous of fuller 

 information should consult the work itself. 



It may be suggested that the discovery by the microscope of 

 fossil parasites, might determine the species of doubtful ex- 

 tinct birds and animals, by the same sort of reasoning as the
