Aucheniae. 
One among a number of llamas, sent to France in 1858 and deposited at 
the Museum de Paris, became mangy and was sent to the school at Alfort, 
where Delafond and Bourguignon examined it. The following year there were 
four more cases. The Sarcoptes gives rise to a scabies which becomes very 
rapidly generalised and forms large greyish crusts, very hard and adherent. 
The disease was contracted by two pupils who handled the animals, and they 
were so severely attacked that treatment was necessary after a month. 
Delafond and Bourguignon (1862, p. 383) say that the parasite is “like that 
of man, the dog and the lion, but add that “ the male has, as special character, 
a short, slender, sharp appendage on the outer side of the ambulacrum.” 
Railliet (p. 634) says that the dorsal scales leave no “clairiere,” and that 
the measurements are ? 340 x 264 /i, $ 245 x 182/*. 
Hydrochaeri. 
Found on Hydrochaerus capybara, the Capybara, Cabiai, or Carpincho of 
S. America and the W. Indies—the largest living rodent. 
Megnin (1893, p. 132) gives its measurements as $ 357 x 300/x, $ 220 x 
160 /*. 
Neumann (1905, p. 19^ -says it attacks ferrets, and he apparently thinks 
it identical with furonis. 
Rupicaprae. 
According to Furstenberg (p. 67), Hering (p. 603) says this Sarcoptes is 
roundish, narrowed posteriorly, irregular (hockerig) at the side, almost hairless, 
but the description is confused. Delafond and Bourguignon, judging from 
Hering’s description and figures (which I have not seen), say that it is noto- 
edric. 
There is further confusion by Hering’s statement that the female has two 
roundish projections, and the male a pair of suckers—which would remove 
it from the Sarcoptinae altogether. 
Wombati. 
There seems to be no description of this form. Dumeril found it in the 
skin, covered with crusts, of a mangy wombat brought from Australia to the 
Museum de Paris, and Fournier pronounced it to be identical with that of 
man. The keeper, and his assistants who prepared the skin, contracted an 
intense scabies with vesicles larger than those of the common scabies of man. 
SARCOPTES ON CATTLE. 
Robin in 1860 announced the discovery of a sarcopt on the ox, but the 
existence of a form proper to the bovidae has until recently been questioned 
and none has been described under the title bovis. Most of the old records of 
scabies in cattle were cases attributable to contagion with mangy animals
