Diagnosis. A species of Bathyuroconger with a slightly reduced gill opening, separated from pectoral-fin base by a distance of less than diameter of gill opening; total vertebrae 201 ‒ 210; color medium to dark brown.

discussion
Remarks. This species has been known for some time, but it was identified as Bathyuroconger vicinus, which has been considered world-wide in distribution. The difference in the form of the gill opening was not noticed previously. The high vertebral count separates it from all other known species of Bathycongrus except the B. cf. vicinus specimens reported below, which have an unreduced gill opening in contact with the pectoral-fin base. The lateral-line pores in the type specimens could not be counted because of damage to the skin on the side of the body.
