Eponymy: Auguste Henri André Duméril (1812–1870), was a physician and zoologist like his father (see next entry) and followed much in his father’s footsteps. [...] (Ref. 128868), visit book page.

背棘 (总数) : 0; 背的软条 (总数) : 65 - 81; 臀鳍软条: 51 - 62; 脊椎骨: 57 - 62. Diagnosis: head oval-shaped to rectangular dorsally; snout broadly rounded; eyes more laterally placed; frontal fontanelle extremely long and narrow; occipital fontanelle oval-shaped to rounded; tooth plates extremely broad (Ref. 248). Supraorbital and `dermosphenotic' bones separated; dermosphenotic somewhat reduced and shows a clearly marked notch (Ref. 248, 101841) although this notch is not observed in all specimens (Ref. 101841). Pectoral spine straight and robust; gill rakers relatively long and distantly set; openings of the secondary sensory canals regularly arranged (Ref. 248). Suprabranchial organ reduced to virtually absent (Ref. 248, 101841).
Colouration: preserved fish show uniform colouration: dorsum, flanks and upper side of paired fins dark brown; ventrum and ventral parts of paired fins light grey to beige; no information known on colouration of living specimens (Ref. 248).
头部椭圆形的到矩形的背面; 吻宽广地圆的; 眼更侧面放置。 额骨囱门非常长而狭窄的; 后头骨囱门椭圆形的圆。 齿板非常宽大。 眶上的与皮蝶骨的' 硬骨分开; 皮蝶骨的略微缩小的而且显示一个清楚显着的凹槽。 胸棘直线与结实的。 鳃耙相当长的而且远远地竖立。 事实上被缩小成的鳃前器官不存在。 第二感觉管的开口规则排列的。
Facultative air-breathing (Ref. 126274)
