The genetic relationships between four species of sticklebacks, Gasterosteus aculeatus Linneaus form trachurus, Gasterosteus wheatlandi Putnam, Pungitius pungitius (Linneaus), and Apeltes quadracus (Mitchill) were estimated by a locus-by-locus analysis of interspecific allozyme variation as well as by a band-counting analysis of soluble proteins in muscle. The locus-by-locus data was analysed both by a qualitative cladistic analysis and by a quantitative phenetic analysis. Both the locus-by-locus analysis and the band-counting analysis generated phylogenies which concord with the previously established relationships among these species. Our analyses indicate that these species have diverged considerably with a genetic identity of only 0.37 between the two congeneric species.

Each of the seven families of rudists (Mollusca, Bivalvia, Hippuritacea) is characterized by distinctive shell-wall architectures which reflect phylogenetic relationships within the superfamily. Analysis of the complex, calcareous, cellular wall of the attached valve of the radiolite rudist Eoradiolites davidsoni (Hill) from the Comanche Cretaceous of Central Texas indicates that its wall architecture is an elaboration of the simpler monopleurid rudist wall and supports possible radiolite-monopleurid relationships.Several well-preserved specimens of E. davidsoni were sectioned, polished, etched, and carbon and gold coated for SEM examination. Maximum shell microstructure detail was displayed by etching with a 0.7% HC1 solution from 80 to 100 seconds.The shell of E. davidsoni comprises a large, thick-walled, conical, attached valve (AV) and a small, very thin, operculate, free valve (FV) (Fig. 1a). The AV shell is two-layered with a thin inner wall, in which original structures are usually obliterated by recrystallization, and a thick, cellular, outer wall.
