(total): 0. Upper eye less than its own diameter from dorsal profile of head. Anterior nostril on blind side not enlarged, its distance from front margin of head about twice in its distance from cleft of mouth. Anterior nostril on eyed side with backward-pointing tube reaching to front border of lower eye. Pectoral fin on eyed-side small, on blind side reduced.
Northeast Atlantic: British Isles south to Senegal (baie du Lévrier) and the Mediterranean.
