SARCOPTES MINOR

infect other rabbits. On the other hand, the transmission of the 

 itch mite of the rabbit to the cat does not succeed. In man S. minor 

 induces an eruption that disappears after about a fortnight. 



[S. minor, Furstenberg, 1861 ("Kratzm.," viii, p. 218), comes in 

 Railliet's sub-genus NOTOEDRES, 1893 (" Zool.," ed. 2, p. 660). Canes- 

 trini raised this to generic rank in 1894 (Prosp. Acarof., vi, p. 724). 



[There are three species : (i) N. notoedres, Megnin = Sarcoptes 

 alepis, Railliet and Lucet (Compt. rend. Soc. de BioL, 1893, xlv, p. 404), 

 and Sarcoptes notoedres var. mitris, Megnin (Parasitologv, 1880, 

 pp. 172-174). This occurs on the black and brown rats and the 

 water-vole. 



[(2) N. cati, Hering, 1838 (N. acta. ac. Leop., ii, 18, xliv, p. 605, 

 figs. 9 and 10), = Sarcoptes minor, Furstenberg (" Kratzm./' 1861, viii, 

 p. 215). Found on the cat in Germany, France, Italy, and Britain. 



[(3) N. cuniculi, Gerlach, 1857, " Kratzm.," iii, figs. 20, 21. It 

 lives on the rabbit and is found in Germany and France. F. V. T.]

The itch mites of domestic animals, which belong to the genera Psoroptes 

 (= Dermatodectes = Dermatocoptes) and Chorioptes (Symbiotes = Dermatophagus), 

 as a rule do not infest and live on man, even when artificially transmitted. It is, 

 however, possible for this to occur. Moniez (" Traite de par.," 1896, p. 559) 

 mentions that a species of Chorioptes probably Ch. bovis had been found on man, 

 as had also Demodex folliculorum. This author also includes Dermatophagoides 

 scheremetewskyi, Bogdanoff (Bull. soc. imp. d. natural., Moscou, 1864, xxxvii, 

 p. 341), which has repeatedly been found on man in Moscow and Leipzig (Ziirn, 

 Ber. d. med. Ges., Leipzig, 1877, p. 38), as Chorioptes bovis.
