Renal and malo organs : Trujla ii/ra, Carua arc distinct from each other, but their ' vasa deferentia' ahnost immediately unite into a common duct, e, which joins the urethra, c, behind the rectum, /(, and terminates at the outlet, ff. In the Salmon and the Herring the ' vasa deferentia' do not unite together until near their termination in the urethra. In the Cod and the Bull-head (Cottiis) the common portion of the efferent duct is much dilated: it forms a saccular seminal reservoir in the Sole. The canal common to the ureter and vas deferens is of great length in the Sturgeon : a valve prevents the regurgitation of the iirine into the spermatic duct. The urethra is usually produced into a f)f''Pill*j which projects con- spicuously from the back part of the cloaca in the viviparous Pcecilia, Anableps, and Blenny: it is large also in the Lump-fish. The testes are almost entirely extra-abdominal in the Flounder and some other Pleii- ronectidoe, extending backward into a kind of concealed scrotum between the integuments and muscles on each side above the anal fin. The testes differ much in form in different Osseous Fishes, but are remarkable in all for their enormous seasonal increase : when fully deve- loped, they are commonly known as the ' milt' or ' soft roe.' In Gymnotus they are two oblong triedral bodies, attenuated at both ends. In the Pipe-fishes {Syn- gnatld) they present the form of two simple elongated straight tubes, fig. 427, y3.' In the Lump-fishes {Cyclopteri) they are di- vided by incisions into lobes: in the Cod a vast extent of the vascular sur- face of the glandular substance is packed into ' XX. vol. iv. p. 48, prep. no.
