under the same name. Olfers described it under the name of Virmus 
trigonocephalus, and Nitzsch, recognizing its true generic relations, gave 
it the name of Menopon pallidum. While Denny, Giebel, and Piaget 
all agree in referring the figure by Redi to this species, 
Linnzus places it under his Pediculus caponis, which 
is equivalent to Lipeurus variabilis N. 
The annoyance that this one species causes poultry 
is probably equal to that of all the other species com- 
bined, for it occurs in great abundance, and almost 
every fowl examined will be found infested. Then, 
too, it passes readily to other species of birds, and 
many instances are recorded where horses kept near 
henroosts have been very seriously troubled by them. 
Some of these accounts seem hardly credible, taken ric. 135.—1Lfeno por.
