Abstract We owe to Leydig (1) the first demonstration that a secretory process is a possibility for the skin of the Fish. In some twelve genera he described the occurrence of specialized cells in the epidermis, to which he gave the common name of “Schleim-zellen,” though subsequent research has shown that several varieties of structure were included in this generic term. Kölliker (2) in 1860, in an investigation of the skins of Myxine and Petromyzon, differentiated two cell-forms. Observing the “thread bodies” of the mucous sacs of Myxine, first clearly described by Johannes Müller (3), he recognized their cellular nature, and found that the epidermis held similar, though less complex cells, from whose contents also, by appropriate treatment, a thread could be obtained. To these epidermic cells of Myxine the name “Fadenzellen” was applied. In addition, clear or finely granular cells, termed “Schleimzellen,” were described.
