摘要：

The cellular organization of the gill, which harbors symbiotic bacteria, is described in juveniles and adults of Codakia orbicularis, a large tropical Lucinidae. The ciliary zone is similar in every species of Lucinidae described and includes the large clear cell which has been previously described as an intermediary cell. The intermediary zone is composed of a few narrow unciliated cells, which bind adjacent filaments together and constitute channels through which sea water circulates along the abfrontal part of the filaments. The lateral zone is more complex in C. orbicularis than in other Lucinidae, being composed of four cell types and differentiated into two distinct regions. The bacteriocytes and intercalary cells occupy the outermost bacteriocyte zone, while mucocytes and numerous cells crowded with proteinic, cystine-rich granules constitute the innermost secretory zone which has not been described in other species. The newly described granule cells are considered to be a key factor in the storage and metabolic conversion of sulfur compounds.
