| comparative shell morphology of lymnaea (bullastra) cumingiana (pulmonata: lymnaeidae) and related taxa in the indo-pacific region. | comparative shell morphology using both quantitative and qualitative parameters was employed to investigate the taxonomic relationship between the endemic philippine species, lymnaea (bullastra) cumingiana and five other lymnaeid "species" in the indo-pacific region, namely: l. (radix) quadrasi (philippines). l. (radix) rubiginosa (indonesia), l. (radix) rubiginosa (thailand), l. (radix) viridis (guam) and l. (radix) viridis (hong kong). fifty randomly chosen adult specimens of each species were ... | 1993 | 8160068 |
| comparative radular morphology of lymnaea (bullastra) cumingiana (pulmonata: lymnaeidae) and related taxa in the indo-pacific region. | the radular morphology of lymnaea (bullastra) cumingiana was compared to that of five other indo-pacific lymnaeid "species", namely: l. (radix) quadrasi (philippines), l. (r.) rubiginosa (indonesia and thailand) and l. (r.) viridix (guam and hong kong) in order to investigate the taxonomic relationship among the six species. although all six species uniformly exhibited a unicuspid, slightly asymmetrical central (rachidian) tooth and tricuspid laterals, interesting differences were noted among th ... | 1993 | 8160067 |
