This symposium was held in Canberra in December 1976 and was attended 

 mainly by Anglo-Saxon workers, more than half of them from Australia and 

 New Zealand. A major feature is the emphasis on monotreraes and marsupials. 

 The 47 papers were reproduced directly from typescripts and vary tremen- 

 dously in format. No discussions are recorded. 



Of the five sections into which the papers are arranged, that on Embryo- 

 maternal interactions and the evolution of viviparity is of most interest 

 to our readers. It contains 13 papers describing work on lizards, mono- 

 treraes, marsupials and eutherian mammals. Nine of the (first) authors are 

 Australian. The summing-up of this section by McLaren is well worth reading. 

 Other sections deal with Evolution of sex determination. Comparative as- 

 pects of reproduction in male vertebrates, and Ovarian cycles and luteal 

 function.

SYMPOSIUM ON GERM AND SOMATIC CELL INTERACTION. 1978

This symposium took place in Paris in July 1977 and had a widely interna- 

 tional attendance. Almost all of the 37 contributions are brief reports of 

 recent research; all are in English with French summaries. They deal with 

 mammals, some lower vertebrates, and some invertebrates (particularly star- 

 fish) . 



Two of the four sections contain papers of interest to developmental 

 biologists (we give the names of the authors concerned in parentheses) . 

 Section 1 is entitled Interaction between somatic and germ cells in the em- 

 bryo (Burgoyne, Byskov, Carlon and Erickson, Wai-Sum O arid Baker) . Section 3 

 is on Cell interaction in the ovary (particularly oocyte maturation: 

 Guerrier et at., Jalabert, Moor, Ozon et at., Schuetz and Cloud, Szollosi 

 et al., Zeilmaker) . The other sections deal with Genetic control of meiosis 

 and Testis cell relationships. 



The volume is well printed and illustrated with top-quality photographs.

Because so many developmental biologists work with amphibians we briefly 

 alert our readers to this volume. It is based on a symposium held in Oxford, 

 Ohio in August 1976 and contains a series of reviews of recently completed
