| Popis: | The hippuritids species Hippuritella lapeirousei (Goldfuss, 1840), Hippuritella nabresinensis (Futterer, 1893) and Hippuritella heritschi (Kühn, 1947)vigere studied through biometrical analysis. For this purpose, the areas of three morphological characters which are related by their biological functions (as describedby Realy, 1992) were measured on transversal sections of lower valves.These morphometrical values are: a) shell area (Sa), b) inner area (la) and c) pillars area (Pl-P2a). This analysis highlighted a morphological similarity between HI. nabresinensis and HI. heritschi, meanwhile the morphometric values for HI.lapeirousei showed to be different. |
