| Microstructural study of the shell of a C. magnifica specimen collected near the thermal vents discovered on the East Pacific Rise at 21°N reveals an ontogenetic process leading from a granulor to various crossed structural types, differing from one region to another. Furthermore, during growth, reperitive structural changes occur within each of the tWO main shell layers. The structural type developed seems to be related to growth rate and environmental fluctuations. [NOT CONTROLLED OCR] |

| Large bivalves of the genus Calyptogena (Vesicomyidae) have recently been discovered on the East Pacific Rise at 21°N, near submarine hydrorhermal springs. Preliminary results of a study of shell microstructure and growth are given. The growth lines which are present do not show either continuity on the whole of the shell, or any evidence Of regular periodicity. In this unusual deep-sea environment, growth could be more or less continuous, in relation with the hydrothermal activity and its fluctuations. [NOT CONTROLLED OCR] |
