Remarks. Mizuno (1970) described Cobitis takatsuensis based on the holotype, five paratypes, and some non-types collected on 28 August 1970 and 10 September 1970 (N. Mizuno, personal correspondence). Mizuno (1970) noted that he had preserved the type specimens of the species in the “ author’s collection ”; registration numbers had not been individually allocated to the type specimens. When TKPM received Mizuno’s collection, the holotype and two paratypes were identified by one of us (Y. Suzawa) based on an interview with Prof. Mizuno, considering also the measurements declared in Mizuno (1970). Subsequently, TKPM-P registration numbers were assigned to the holotype and two paratypes. Mizuno’s collection, as received by TKPM, includes two specimens (TKPM-P 3009, 2 specimens) of C. takatsuensis, excluding the holotype and two paratypes. According to the accompanying labels written by Prof. Mizuno, TKPM-P 3009 were collected from the Takatsu-gawa River System on the same date as the holotype. However, the SL of TKPM-P 3009 (female: 60.4 mm SL, male: 47.9 mm SL) does not match the SL of any paratypes described in Mizuno (1970). It is highly likely that these specimens are non-types, no
