Note: Embryonic and larval development of Calloria inconspicua (Brachiopoda, Terebratellidae)

Carsten Lüter*

Early development of Calloria inconspicua (Sowerby, 1846) from Otago Harbour, South Island and Goat Island, North Island, New Zealand has been precisely documented by Chuang (1996). During a recent study of brachiopod development at Portobello Marine Laboratory, Dunedin, embryonic and larval stages of C. inconspicua were obtained by artificial insemination. Although laboratory conditions were almost identical to Chuang's, the duration of life stages turned out slightly different. A summary 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 relative to Chuang's line drawings.
