Table 3 Some morphological and morphometric data of Cardiomya ornatissima (d’Orbigny, 1853). Comparative data on the length and height of the valves, size of rostrum and number of ribs of the examined material. Dimensions in mm. The number in italics means the average value of the measurement

From: Septibranchia (Mollusca: Bivalvia) from the North and Northeast Coasts of Brazil
