Memoirs: Ecdysis in a Teleostean Fish, Agriopus

J.D. F. GILCHRIST M.A., D.Sc.1

1 Professor of Zoology in the University of Cape Town

(1) The Teleostean fish Agriopus appears to shed its skin at certain times.

(2) This shed skin consists of numerous elongate columns, which are striated longitudinally and are continuous with the outer epidermal cells.

(3) The walls of the column are composed of transverse striations, which are prolonged for some distance into the substance of the column.

(4) The walls of the cells of the epidermis are composed of such fibrils or striæ, and it is concluded that the columns represent a greatly elongate and transformed part of the outer cells.

(5) In the columns are also transverse septa or lines, the nature of which is not evident.

(6) The striated columns are compared with certain features in the enamel prisms of mammals, and with the striated elongate cells of the enamel organ of Teleosts.
