discussion
Remarks. USU 0 1303 was reported by Séret and Andreata (1992) as Haptenchelys texis. The specimen is poorly preserved, lacking skin, dorsal- and anal-fin rays, and infraorbital bones, and the musculature is disintegrating. The bones have also suffered from decalcification, making counts of vertebrae on an x-ray very difficult. The number of vertebrae seems to fit with H. australis: total vertebra ca. 135, precaudal vertebra equal to 60 (Karmovskaya & Merrett 1998). Additional material collected in Northern Brazil confirms the existence of H. australis in adjacent waters.
