The main points of Fiirstenberg’s description are these: 
Female. Body nearly round, the thorax broader than the abdomen, the 
folds at the side moderately deep. Dorsal scales short, ending in a terminal 
chitinous portion which is generally rounded, sometimes pointed—only occa¬ 
sionally nail-like (genagelte) scales. Notothoracic cones long, acorn shaped; 
notogastric spines fairly long and apparently sharp-pointed. 345 x 342/z. 
Male. Oval, nearly egg-shaped, a few marginal dorsal scales. 243 x 188 p. 
They live in the skin and crusts of Egyptian pygmy goats (Zwergziege). 
The specimens were sent by Prof. Muller of Vienna (Furstenberg p 214 
PL VII, figs. 72-79). 
The disease chiefly affects the head and ears, then the trunk, and lastly 
the limbs. It is often epizootic with considerable mortality. Whllraff recorded 
a case in Grisons during the years 1851-4. In the spring of 1853, out of 
2596 goats 1015 had developed mange and 250 had died. At the end of the 
attack 500 goats had been lost. 
Henderson recorded it in 1851 from a Persian goat in London. Except 
for the Swiss cases it has always been found in African or Asian varieties of 
goat. 
It seems readily transmissible to-other animals, and in the Swiss epizootic 
horses, oxen, sheep, pigs and especially man caught the disease from the 
goats, and had it in a severe form. In Henderson’s case it passed to the horse 
and thence to man. 
Delafond and Bourguignon (1857) say: “this species is remarkable for the 
size of its ambulacra (ventouses) on the anterior legs, and for the length of 
its posterior hairs.” 
Hebra found no difference between this Sarcoptes and that of man. 
The goat is also subject to a Chorioptic scabies.

1862). 
Dorsal scales longer than broad; notogastral spines long , slender , pointed; 
notothoracic cones short , blunt , swelling in the middle; epiandrium feebly united 
to epimere.

Canestrini ( Prosp. Acarof. It., vi. PL 64) figures this sarcopt from pre¬ 
parations sent him by Trouessart. They were prepared by Neumann, and 
bore the label “ Sarcoptes scabiei du lion, Menagerie Pianet, 3, v. 92.” The $ 
shows remarkable dorsal projections of the armature of the first legs. 
The long account given by Delafond and Bourguignon (1862, pp. 229-233) 
remains our chief source of information about this Sarcoptes —which, however,
