NOTE - EMBRYONIC AND LARVAL DEVELOPMENT OF CALLORIA-INCONSPICUA (BRACHIOPODA, TEREBRATELLIDAE)

Early development of Calloria inconspicua (Sowerby, 1846) from Otago H arbour, South Island and Goat Island, North Island, New Zealand has be en precisely documented by Chuang (1996). During a recent study of bra chiopod development at Portobello Marine Laboratory, Dunedin, embryoni c and larval stages of C. inconspicua were obtained by artificial inse mination. Although laboratory conditions were almost identical to Chua ng's, the duration of life stages turned out slightly different. A sum mary of the results of this study, of Chuang (1996), and of Percival ( 1944), who first described the development of C. inconspicua, is given in Table 1. In addition, SEM photographs of four developmental stages are presented, which show differences in ciliation of life stages rel ative to Chuang's line drawings.
