Journal of the Academy of Natural Sciences of Philadelphia, Ser. 2, v. 4

In the 1857 Proceedings of the Academy of Natural Sciences of Philadelphia (vol. 9, p.84, for the March 31 meeting), Lea spelled the name only as 'Unio Texasiensis.' In a later but more detailed work in 1860, Lea spelled the name only as 'Unio Texasensis,' without comment. Turgeon et al. (1998: 37, 185) note the two spellings and retain the original spelling, suggesting the later spelling is an unjustified emendation

ITIS taxonomy is based on the latest scientific consensus available,
and is provided as a general reference source for interested parties.
However, it is not a legal authority for statutory or regulatory purposes.
While every effort has been made to provide the most reliable and up-to-date
information available, ultimate legal requirements with respect to species
are contained in provisions of treaties to which the United States is a
party, wildlife statutes, regulations, and any applicable notices that have
been published in the Federal Register. For further information on U.S.
legal requirements with respect to protected taxa, please contact the
