The genus Cnemidocoptes contains a number of species that occur on various birds, including poultry. Some live at the base of the feathers, others produce a crust of loosened tissue and dead skin similar to that of Norwegian itch. They may begin on the comb or skin of the feet, but gradually spread down the neck or up the legs. The species are all short and broad, with short legs and with very few hairs above, and these small. They give birth to living six-legged larvae, which, however, appear to have hatched from eggs while in the body of the parent. C. mutans Robin (fig. 274) is the itch mite of domestic fowls, at times a very serious pest. The disease it produces is known as'' scaly leg,'' since the mites are most abundant on the legs. The best remedy is to soak the legs in warm soapy water until the crusts are loosened; then apply sulphur ointment. Bathing the affected portions in a solution of some coal- tar creosote preparation is also a good remedy; the treatment should be repeated in a. Fig. -Otodectes cynotis: Female, illustration.)
