Of the three major parts that on development and regulation is of most 

 direct interest to our readers. It occupies the middle third of the text 

 and has chapters on spore germination and the thallus, on vegetative and 

 sexual behaviour, and on multicellularity in ascomycetes and basidiomycetes , 

 with a separate chapter on morphogenesis in the slime moulds. The informa- 

 tion assembled in these chapters is quite up to date as textbooks go, al- 

 though pattern formation in Dictyostelivm is not treated. 



The book is attractively produced and very well illustrated.

This is the 3rd issue of the prestigious treatise edited by Seidel. It 

 conforms to the issues that have appeared so far in that much attention is 

 also given to the structure and biology of the adults, to vegetative repro- 

 duction, and to maintenance and rearing methods. 



The volume is well produced and illustrated with good line drawings from 

 various sources. It has a glossary of technical terms and a bibliography of 

 some 140 titles, 

 (see also notice no. 15.)

The first two instalments of this ambitious new treatise were announced 

 in Gen. Embryol. Inf. Serv. vol.17, 2, 1978. Meanwhile a volume on the 

 nemerteans by Friedrich has also appeared (see notice no. 14). The present 

 volume deals in three separate chapters with the Onyahophora, Tardigrada 

 and Pentastomida. Apart from the descriptive embryology, each chapter deals 

 briefly with systematics, adult characteristics, reproduction and way of 

 life (as well as rearing methods for the first group) . 



The book is well illustrated with line drawings. from various sources and 

 a few micrographs, and has a brief glossary.
