Gnathophis cinctus (Garman, 1899) .

Catalina Conger or Hardtail Conger. To 41.9 cm (16.5 in) TL (Fitch and Lavenberg 1968). Santa Rosa Island, southern California (Fitch and Lavenberg 1968) to Peru (Robertson and Allen 2002), including Gulf of California (Gall et al. 2020), and Islas Galápagos (Grove and Lavenberg 1997). Depth: 9–366 m (30–1,200 ft) (min.: Fitch and Lavenberg 1968; max.: Miller and Lea 1972). Various other deeper records (e.g., 4,409 m (14,460) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California)), are based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
