170 INSECTS AFFECTING DOMESTIC ANIMALS. 
THE LOUSE OF THE CAMEL. 
(Hematopinus cameli Redi.) 
We follow Giebel and Piaget in admitting this species, although it 
does not appear to have been observed by any modern naturalist. 
Piaget says (Les Pédic., p. 644): “‘ La figure que donne Redi, le seul 
qui ait observé cette espéce, se rapproche beaucoup de celle de Purius.” 
LicE INFESTING THE GIRAFFE, DEER, AND ANTELOPE. 
(Hematopinus spp.) 
Closely related to the lice infesting the other hoofed quadrupeds are 
those infesting respectively the giraffe, deer, and antelope. The spe- 
cies infesting the giraffe (Camelopardalis giraffa) was described by 
Giebel under the name Hematopinus brevicornis ; that infesting the 
deer was first mentioned by Redi and described and named by Nitzsch 
as Hematopinus crassicornis; it is recorded from the red deer (Cervus 
elaphus). The Hematopinus tibialis Piaget, from Antilopa maori, is, 
according to its author, represented by varieties on the Antilopa sp. 
and the Antilopa subcutturosa, and he considers it possible that the H. 
cervicapre Lucas, from Antilopa cervicapra, is also a variety of this 
same species. 
THE SUCKING LOUSE OF THE GOAT. 
(Hematopinus stenopsis Burm.) 
We have no record of this species having been observed in this coun- 
try, and judging by the references to it in standard works it must be 
of rather rare occurrence in countries where these animals are kept in 
greater abundance than here. 
The species is not, so far as at present known, transmissible to any 
other domestic animal, and if ever becoming abundant, will doubtless 
yield to the treatment used for the other species, though the long hair 
would make some of them more difficult of application. On this account 
pyrethrum would seem to be most practicable. 
THE SHEEP Foot LOUSE. 
(Hematopinus pedalis n. sp.) 
We would hardly expect to find an entirely new form of louse on so 
common a domestic animal as the sheep at this late period of investi- 
gation of animal parasites. I am able to announce, however, a species 
which seems to have entirely escaped observation heretofore, and, more- 
over, to describe a habit of distribution of the parasite on its host which 
has, so far as I know, no paraliel among the related species. This _ 
suctorial louse of the sheep occurs only, as all examinations so far indi- 
cate, upon the legs and feet below where the long wool is found. It is
