Abstract: 
Lipovitellin-phosvitin crystals from oocytes of the sturgeon (A. boeri L.) and the tuatara (S. punctatus [Gray]) have been shown to be orthorhombic like all such known crystals from vertebrates higher than cyclostromes. Lattice parameters and projected crystals views also resembled closely the hitherto known cases. The high evolutionary conservation of this crystal structure probably reflects a cell-biological significance of the tertiary structure of crystal constituents, especially of the lipovitellines. A comparative consideration of crystallographic data from cyclostomes and higher vertebrates suggests that cyclostomes started with one species and all higher vertebrates with two species of lipovitellin molecules.
