This book is a report on a symposium held in Coral Gables, Fla., in March, 

 1961. In it took part 64 North American biologists from different disciplines, 

 but all working with, or interested in coelenterates. The book contains the 23 

 papers delivered, followed by records of the group discussions. The many- 

 sided significance of coelenterate organisms is illustrated by the variety of 

 subjects covered by the various contributions. We list the following topics: 

 cytology, cytochemistry, ultra-structure, cytogenesis, feeding, nutrition, tissue 

 culture, symbiosis, calcification, patterns of colonial growth, aging, regeneration, 

 budding. The aim of the symposium was the establishment of an interdisci- 

 plinary synthesis. Much of the work recorded is still in a preliminary phase. 



The book is profusely illustrated. Many electron-micrographs are included. 

 There is an extensive subject index.

The reason why we announce this monograph here is that it contains a 

 chapter of 35 pages dealing with reproduction and development in leeches. 

 The chapter discusses fertilization, egg laying and brood care, egg develop- 

 ment in general, and the pattern of development in glossiphoniid, gnathobdel- 

 liid, and piscicolid leeches. It is illustrated with some 30 excellent line drawings.
