背棘 (总数): 0; 背的软条 (总数): 69-94; 臀鳍软条: 52 - 70; 脊椎骨: 56 - 61. Diagnosis: body less elongate, its maximum depth 11.9-16.4% SL (m=14.1); head length 21.0-26.0% SL (m=24.1) (Ref. 57129, 81644). Head rectangular dorsally; snout extremely broadly rounded; eyes more laterally placed (Ref. 248). Interorbital distance 45.4-54.3% HL (m=48.8) (Ref. 57129, 81644). Tooth plates extremely broad (Ref. 248), width of premaxillary tooth plate 30.4-38.9% HL (m=34.9), and of vomerine tooth plate 26.1-33.9% HL (m=29.7)(Ref. 57129, 81644). Frontal fontanel long and narrow; occipital fontanelle long and oval-shaped (Ref. 248). Supraorbital and "dermosphenotic" bones separated in specimens up to 200 mm SL, in larger specimens they usually become joined (Ref. 248, 101841)). 7-13 (Ref. 57129, 81644) or 7-14 (Ref. 101841) gill rakers on first gill arch. Suprabranchial organ well developed (Ref. 248, 101841). Pectoral spine slender, its outer side showing strong downward serrations (Ref. 248, 81644). Dorsal fin length 59.5-67.9% SL; distance from dorsal to caudal fin 1.2-4.3% SL (Ref. 57129, 101841). Flank neuromasts arranged in a regular pattern (Ref. 81644). Colouration: no information on colour in life (Ref. 57129, 101841). Preserved specimens: dark brown on back and sides and pale brown to beige/whitish on belly; pectoral and pelvic fins sometimes with a pale distal band; caudal fin sometimes with alternating light and dark vertical bars (Ref. 57129, 81644). Never an irregular pattern of small white spots on body (Ref. 101841).
头部矩形的背面; 吻非常地宽广地圆的; 眼更侧面放置。 额骨囱门长而狭窄的; 后头骨囱门长而椭圆形的。 眶上的与皮蝶骨的' 硬骨分开了在超过 200 mm SL 的标本中。 齿碟非常宽大。 胸棘细长的; 外部的旁显示强的向下锯齿。 鳃前的器官发展良好的。 第二感觉管的开口显示一个普通的型态。

生物学特性     字汇 (例如 epibenthic)

Data on the diet of C. walkeri (=C. camerunensis) showed larvae of mayflies, chironomids, and caddis insects to be the main food of small and middle-sized specimens (Ref. 248). Stomach content analysis showed presence of practically everything edible from plant remains, insects and their larvae to fish remains (Ref. 78218).

资料显示 C. walkeri(= C. camerunensis) 的食性显示孚游类,宝刀鱼与石蚕昆虫的仔鱼是小而中等标本的主要食物.(参考文献 248)
