Later, studies by Schmitz and Schultz (1969), Alikhan (1968, 1969a, 1971) and Hassall and Jennings (1975) confirmed the general structure outlined. The digestive tract consists of a foregut, midgut and hi

The procedure involved in my own studies consisted principally of two criteria (Warburg 1964), firstly, the behaviour of an individual and secondly, the behaviour of a small group of animals (up to 10). With the first criterion I use

The Reproductive System and Reproduction,1896a, b). The marsupium of the oniscid isopods is formed by five thoracic segments (Nos. 3–7). Four processes hang down from the thoracic epithelium; they are opaque or transparent, soft and surrounded by opaque mucus (Akahira 1956). There are three tubular evaginations per somite, called cotyledon

Population Structure and Fluctuation, families (see Table X in Warburg et al. 1984). A typical characteristic of population structure is the large number of young within a population. At times they comprise the bulk of the isopod population in any single location (Sutton 1968; Sunderland et al. 1976). However, there is a large variatio
