Descriptive remarks: Jenyns (1842), Perugia (1890), Figueiredo & Menezes (1980), Nakamura (1986) and Carvalho-Filho (1999) reported that Acanthistius patachonicus is grey to brownish, with dark bands not always visible on the sides, and irregular lines “ zigzagging ” in different directions over the body, dorsal fins and anal fins. The lined “ zigzag ” pattern of A. patachonicus is visible in individuals of all ages (Figueiredo & Menezes 1980; Carvalho-Filho 1999). Our observation of live and preserved specimens confirms that pattern (Fig. 5). Reported ratio between the length of the pectoral and pelvic fins is in the range of 1.18 to 1.28 (Figueiredo & Menezes 1980), and 1.12 to 1.27 in the specimens studied by us. De Mahieu & Capezzani (1976) counted 80 – 100 scales on the lateral line (n = 700), Nakamura (1986) reported 84 – 98, and Figueiredo & Menezes (1980) 68; clearly, the former authors were referring to the total number of scales on the lateral line (lateral scale series), and the latter to pored scales only (lateral line scales). In the specimens examined by us the number of pored lateral line scales ranged between 67 and 70. Coincidentally with Berg (1899) we observed th
