habituation of plant cells in vitro, tumours induced by chemicals and irra- 

 diation, and White's fir tumour. Much attention is given to the nature of 

 the causative agents, the mechanisms of tumour induction, and the effects on 

 the host plant. 



The book is illustrated with line drawings and photographs. The bibliogra- 

 phy contains well over 1,000 titles and is up to date until 1976.

A.C.GIESE and J.S.PEARSE, eds. 1977. REPRODUCTION OF ^4ARINE INVERTEBRATES, 

 vol. IV; Molluscs: Gastropods and Cephalopods 



Academic Press, New York, etc. XII, 369 pp., 112 figs., 2 3 tabs., author, sub- 

 ject and taxonomic indexes. $ 38.00, £ 27.00 



The first three volumes of this 7-volume treatise were announced in Gen. 

 Embryol. Inf. Serv. , vol.16, parts 1 and 2. The present volume has three 

 chapters on gastropods {Prosobranahia^ Opisthobranahia and Fulmonata) and 

 three on cephalopods [Nautiloidea^ Deoapoda and Octopoda) . The sections on 

 embryonic and larval development are almost entirely descriptive in nature; 

 that in the chapter on opisthobranchs is very short and the embryonic devel- 

 opment of Nautilus is not known. 



The chapter on prosobranchs has been updated by a bibliography covering 

 the years 1970- '76. The volume is a mine of information and is profusely and 

 beautifully illustrated.
