Description:Excerpt from Studies on Acari, Vol. 1: The Genus Demodex, Owen The present work constitutes the first part of the studies on parasitic Acari in which the author, Mr. S. Hirst, has been engaged for some time. The representatives of the genus Demodex are skin-parasites of microscopic size. Although certain species give rise to troublesome affections of the skin, others are not definitely known to be harmful. D. folliculorum, a parasite which is so common that it has been stated to occur in "practically every human being," is regarded as harmless by the majority of the authorities who have studied it, although it has been accused by other students of the group of being instrumental in carrying certain grave diseases. Since these animals live embedded in the skin of their host, their detection is not easy without practice; but the success of the author in finding them in Mammals in which they had not previously been recorded, or had been supposed to be rare, makes it appear probable that many species remain to be discovered. An accurate knowledge of this group is highly desirable, as there are many instances of parasites at first believed to be harmless which have been found, with increased knowledge, to be extremely injurious to the health of their hosts, either by their direct effects or by acting as the carriers of disease. The thanks of the Trustees are due to Messrs. Taylor and Francis for permission to reproduce figs. 39, 41, 42a, 46, 47; to the Belgian Government, Lt.-Col. A. W. Alcock, F.R.S., Lieut. Leslie Linzell, and M. R. van Saceghem for specimens; and to Mr. M. A. C. Hinton for assistance in connexion with the Mammalian hosts.
