The tail appears to attach to the margin of the middle piece. The spermatozoa of the two kinds of fishes differ from one another in form and size of the head, as well as in size of the tail. The head of the loach sperm is' spheroidal, usually micra in long axis and micra in short axis, with a tail about micra long. The head of the funa sperm is spherical, approximately micra in diameter, having a tail about micra in length (Figs. 1 and 2). 2. The ovum of funa The ripe egg is nearly spherical in form, to mm. in diameter, with opaque orange coloration. The egg envelope is comparatively thick and tough, consisting of external and internal layers. The external layer is strongly ad- hesive when the egg is immersed in water. The micropyle, penetrating the enve-.
