Summary. In larval Notopterus the latero‐sensory canals in the head are extraordinarily spacious and run through the head like huge tunnels. The canal‐system is remarkable in not possessing any opening to the exterior. The disposition of the canals follows the generalized Teleostean pattern. The cavity of the supraorbital canal is isolated from the rest of the system. There are, altogether, 36 neuromasts enclosed within the canals on each side of the head innervated in the typical Teleostean manner. The lateral canal of the body has not yet been formed, ...
