"In this edition several important alterations have been made in the construction of the book. A chapter has been inserted dealing with the physiology of the internal secretions and their relationships ... The position of this chapter has necessitated the renumbering of the subsequent chapters; and two chapters have been added in later parts of the book." - Pref.

The literature associated with descriptions and definitions of the sucker-like attachment organs in trypanorhynchs, termed either bothria or bothridia, is reviewed. There are descriptions of 14 trypanorhynch species representing 10 families. In none of these trypanorhynchs was a membrane separating the attachment organ from the scolex parenchyma described, one of the definitions used to distinguish bothria from bothridia. Transmission electron microscopy of the bothria of the trypanorhynch species Nybelinia queenslandensis Beveridge & Jones, 1998 (Tentaculariidae) and Otobothrium mugilis Hiscock, 1954 (Otobothriidae) also failed to show any membranous structure separating the surface of the attachment organ from the cestode parenchyma. The sucker-like attachment organs of trypanorhynchan cestodes appear, therefore, to be bothria rather than bothridia. As a result, changes in the terminology of related features of the scolex are proposed here. Henceforth, the pars bothridialis should be referred to as the pars bothrialis and the bothridial pits should be referred to bothrial pits.

The article adopts a developmental approach to successful human aging by exploring the concept of generativity in relation to a study of older Australians' lived experiences of involvement in the family and community. Qualitative data, collected through focus group interviews, were analyzed interpretively using recent developments in Erikson's theory of generativity as a framework. As a result, the present study contributes an in-depth understanding of the role of generative acts to the lives of older people. The data provide illustrative support for Erikson's contention of a generativity/stagnation crisis in later life. Involvement in the family and community is seen as a productive and generative activity, which promotes a positive experience of aging. Two further emergent themes are also explored. First, the experiences of study participants illustrate the reciprocal and cyclical nature of grand-generativity, and the importance of intergenerational relationships. Finally, the data contribute to our knowledge of cultural generativity, and in particular the passing on of cultural knowledge through narratives and modeling.
