With the Oxytrichidse we arrive not only at the most highly specialized group ofthe Hypotricha, but, in many respects, at that also of the entire class of the Infusoria-Ciliata. Structural differentiation is manifested more particularly in this family inthe remarkable development and relegation to varied purposes of the appendicularor locomotive organs, and which, while in all instances more or less complex modifi-cations of ordinary cilia, exhibit mostly a wide departure from the structures bearingthat title as met with in the orders previously described. By many earlier writers,indeed—as explained more at length in the introductory chapter, see pp. 64 and 65 —these appendages were regarded as distinct organs, and have been distinguished bythe respective titles of setae, styles, and uncini, &c.; these terms are, however, in thistreatise retained only in an adjective or qualitative sense.
