Ariosoma-type larvae with outer-intestine (exterilium) of the eel family Congridae from the western North and Middle Pacific are described and characterized. Nine types are recorded based on pigmentation, position of last vertical blood vessel at myomere level and number of myomeres. Five types from the western North Pacific and their relationship with the adult are discussed. None has been conclusively identified with the adult. A key is provided to the exterilium Ariosoma-type larvae known from the western North and Middle Pacific. Distribution maps showing capture locations are given for each type.
