cies of .Jrichodectes as infesting the goat. These two species 
are very similiar to each other, and are, perhaps, only varie- 
ties. His illustrations are very fine, and his figures of the 
female.of limbatus (fig. 88)and of the male of climaz (fig. 89) 
are reproduced. 
The former species, limbatus, is fairly common in some 
localities, but not here in Minnesota. It usually occurs 
among the coarse hair along the back and sides of the in- 
fested animals and causes much discomfort, and in extreme 
cases even a form of scab. 
A number of other hair-lice are found upon mammals.
