Abstract
    The larva of the congrid eel A. alcocki is identified and described here for the first time on the basis of juvenile and metamorphic specimens from Hawaii and the western Atlantic. It is an elongate leptocephalus with ten prominent, pigmented loops in the gut. In this it differs from other congrid larvae and approaches the condition found in certain ophichthids. Some ophichthid larvae have the characteristic swellings of the gut reduced and approach the condition found in congrids. Characters which distinguish congrid from ophichthid larvae are presented.
