' M = Mediterranean. S = southern oceans, key to other regions as in Table I 70, 



terranean flatfishes and more recently Russell (1976) provided 

 an extensive review of previous European contributions. 

 Knowledge of ontogenetic stages of western Atlantic flatfishes 

 is summarized by Martin and Drewry ( 1 978) and Fahay ( 1 983). 

 Early life histories of North Pacific flatfishes are treated com- 

 prehensively by Pertseva-Ostroumova { 1 96 1 ). Japanese and In- 

 dian workers have provided a long list of contnbutions to flatfish 

 life history studies and Amaoka (1969, 1979), Hensley (1977) 

 and Futch (1977) employed ontogenetic characters in assessing 



phylogenetic relationships. The individual contributions to flat- 

 fish ontogeny are too numerous to summarize concisely and are 

 cited in the section that follows.

 Eggs are known for most species in Pleuronectidae and 

 Scophthalmidae and for only a few to moderate numbers of
