Halosaurus johnsonianus Vaillant [L. L.] 1888 View in CoL : 181, Pl. 15 (figs. 2-2d). Off western Sahara, 23°50'N, 17°17'W, depth 1,139 meters. Lectotype: MNHN 1885-0361 About MNHN . McDowell 1973: 56 –57 (key); Harrisson 1972: 254; Maul 1976: 20 (description); Sulak 1986a: 593 –598 (description, key); Sulak 1990: 131. GoogleMaps

Material examined. MHNUSC 25013- 1, 354 mm TL, 19th July 2009, Le Danois Bank; 43º55.22'N—4º47.92'W; 1,198 m depth; MHNUSC 25013- 2, 404 mm TL, 19th July 2009, Le Danois Bank; 43º55.22'N—4º47.92'W; 1,198 m depth.

Description. Body shape eel-like, moderately compressed, elongated and attenuated to the caudal peduncle; body very slender, its greatest depth is contained 2.8–3.1 times in the head length; top and sides of head scaled nearly to tip of snout; opercle scaled; lateral line scales only slightly enlarged, forming a dark band; gill rakers longer than opposite gill laminae; pyloric caeca very short and black. The main morphometric and meristic characteristics are presented in Table 5 View TABLE 5 .

Habitat and distribution. Benthopelagic, between 680–2,100 m depth and 4–11ºC. Eastern Atlantic, from the Porcupine Seabight , Portugal and southern Spain to Mauritania including the Azores, Cape Verde, and Canary Islands ( Maul 1976; Sulak 1990; Priede et al. 2010)
