Abstract

A REVISED chromosome number of 28 has been established for the amphibian Amphiuma means tridactylum Cuvier, the congo eel, from studies of both somatic and meiotic divisions in smears of testicular tissue. The somatic complement of 28 was clearly demonstrated in mitotic prophases and metaphases, most of which were of karyotype quality (Figs. 1 and 2). Counts derived from the various stages of meiosis, notably diakinesis (Fig. 3) and anaphase, further support the validity of the somatic count.
