probably also is the main storage organ of P. The 32p is about 9 times as 

 concentrated in the digestive gland of Venus as in Mya . Concentrations in 

 other tissues are about the same in both species. The second highest con- 

 centration was found in kidney, and it was probable that this organ was 

 responsible for loss of 32p to the surrounding medium. Smallest concentra- 

 tions were found in muscle and shell. Up to 94% of the 3 ^p present in 

 Phaeodactylum was assimilated. There was no marked transfer to gonads.

Many species do not spawn until a certain temperature is reached, such as 

 Venus (Ansell 1961) . This review article undoubtedly covers many aspects 

 of ecology and functional morphology of Mercenaria (Venus) mercenaria, but 

 this was the only specific reference found. Sections cover habit and habi- 

 tat, breeding, embryology and development, growth, shellfish cultivation, 

 genetics and variation, and geographical distribution and population studies. 

 There is an extensive bibliography. - J.L.M.

The sulfonic amino acid taurine was found only in marine mollusks, not 

 freshwater or terrestrial forms. Marine species examined included 

 Venus mercenaria (Simpson et al. 1959) . The technique was paper 

 chromatography. This review paper concluded that amino acid metabolism in 

 mollusks is poorly known. In marine mollusks the only subject studied to 

 any extent has been the role of amino acids in osmoregulation, in which 

 taurine plays an important role. - J.L.M.
