pattern in later development (eye development, leg regeneration, the role of JH in pattern 

 formation, and chromosome puffing and ecdysone). All papers are followed by brief dis- 

 cussions which are often illuminating. Most reference lists go well into 1976. 



The book is very well produced and well illustrated with line drawings and photo- 

 graphs.

H. M. McCAMMON and W. A. REYNOLDS, organizers. 1977. BIOLOGY OF LOPHO- 



PHORATES 



Amer. Soc. of Zoologists, Thousand Oaks, Calif. American Zoologist vol. 17, 1. 150 pp., 

 139 figs., 11 tabs. 



This symposium was held in August 1975. The Lophophorates are a loose group inclu- 

 ding the Bryozoa, Brachiopoda and Phoronida. Of the 13 papers in this volume six deal in 

 one way or another with descriptive aspects of the development of these organisms: 

 embryonic, larval and postlarval development, colony development, and growth and dif- 

 ferentiation of adventitious structures. All of these papers report on original research 

 against a varying background of review material of a morphological or evolutionary 

 nature. They are written by specialists from five countries and are very well illustrated 

 with line drawings, photographs and micrographs.

Academic Press, New York, etc. XIV, 644 pp., 224 figs., 26 tabs., author, species and sub- 

 'ject indexes. $ 58.50, £ 41.55 



Contents: 1. Color change (Bagnara); 2. Physiology of molting (Larsen); 3. Ground 

 substance: an anuran defense against desiccation (Elkan); 4. The physiology of Amphi- 

 bian cells in culture (Rafferty); 5. Immunity mechanisms (Cooper); 6. Pathology in the 

 amphibia (Elkan); 7. The nervous system (Oksche and Ueck); 8. The visual system 

 (Ingle); 9. The auditory system (Capranica); 10. The biology of metamorphosis (Dodd 

 and Dodd) 



It is particularly the last chapter of this volume that is of special interest to develop- 

 mental biologists. It is a well-organised and authoritative review, which moreover presents 

 a new theory of thyroxine action in metamorphosis. Several other chapters (notably chs. 

 4,5,6 and 7) contain information of developmental relevance. 



' Most of the chapter bibliographies are up to date until 1974. The book is well pro- 

 duced and illustrated.

Although this book by a great authority is largely a guide for the identification of 

 early fish stages in ecological studies, it could be useful to fish embryologists as a refer- 

 ence work and for its additional information. It is a definitive work. 



After a series of brief chapters dealing in a general way with such matters as the egg 

 and its development, the larva, the postlarva, and feeding habits, 40 families are taken up
