Canis vulpes. 
Fiirstenberg’s description is in effect as follows: 
Female. Body long-oval, testudiniform; dorsal scales in rows; notothoracic 
cones rather long, curved, with the points bent backwards and downwards. 
Notogastric spines long, not very strong, slightly curved, and apparently 
sharp-pointed. 442 x 315,u. 
Male. Body nearly round, not much longer than broad; a few dorsal 
scales, only at the boundaries of the thorax and abdomen; otherwise with 
the armature of the $ of Scabiei-crustosae. 245 x 185/r.

(after Fiirstenberg). enberg). 
The female, though inferior to the human Sarcoptes in size, resembles it 
in general appearance. The bulging of the fourth thoracic segment is not so 
marked as in Scabiei-crustosae , and the sensory hair is only of medium size. 
The disease it conveys is like that of Scabiei-crustosae, causing crusts often 
half-an-inch thick. 
The specimens were from a mangy fox, the tail of which was sent to 
Fiirstenberg by his brother in 1857 from Gagen in Riigen. It arrived three 
days after the animal was killed, but the mites were still alive, and continued 
to live three or four days more (Fiirstenberg, p. 213, PL VI). 
Railliet (1895, p. 659) says that Walz first recorded this mite in 1809.
