The innervation of free neuromast (sensory papillae) rows is described from Sihler wholemount preparations of four species of eleotridine gobies, one ( Perccottus glenii ) representing the ‘longitudinal’ type of neuromast arrangement, the others ( Butis buits, Bostrychus urophthalmus, B. marmoratus ) the ‘transverse’ arrangement. In the latter, the characteristic transverse cheek rows (1–7) are innervated from the infraorbital trunk of the anterior lateral‐line nerve. Longitudinal cheek rows b and d , and the three opercular rows, ot, os and oi , common to all species, are innervated by rami of the hyomandibular trunk of the same nerve. Two neuromast groupings are shown to have a mixed nerve supply. For the median preorbital snout rows, there is innervation from the infraorbital ( s 3 and r ) as well as the supraorbital ( s 1 and s 2 ) trunks of the anterior lateral line nerve. The anterior dorsal rows are supplied both by the posterior lateral‐line supratemporal ramus (rows g and m ) and the anterior lateral‐line supraorbital trunk (rows o and n ). The neuromast rows, under the designations of Sanzo, are tabulated according to innervation and their putative origin in the phyletic replacement of a complete head canal system seen in more generalized percomorph fishes.
