In many bony fishesthe middle fibres of the caudal myocommas are dis-posed in two cones; a transverse section of the tailsection of as m 1^3, shows the two concentric series of cutMackarei. segments of the sheathed cones, on each side of thespine. The portions of the myocommas above the lateral linebecome grouped, in fish-like Batrachia and in Ophidia, into threelongitudinal muscles, comparable respectively to the 6spinalisdorsi,f longissimus dorsi, and i sacrolumbalis, the portions belowthe line responding to certain intercostals and the c rectus abdo-minis, of higher vertebrates. The myocommas of one side are separated from those of theopposite side of the body by the verteb
