In treating of Nucula obliqua, Lamarck, I suggested that whereas the type of that species had a smooth inner margin to the valve and was a native of Tasmania, the name had been in error applied to a much larger shell from tropical Queensland with an inner margin microscopically crenulated and with long rake-like teeth. For this Queensland form I proposed the name of Nucula superba.
The size and habitat of Nucula loringi, Adams and Angas, correspond to that of N. superba, but their phrase "margine intus simplice," is inconsistent. The crenulation of the inner margin of N. superba is only visible on good specimens and under a lens. But had it been overlooked by the authors, Mr. E. A. Smith would have referred to N. loringi in discussing the large Queensland Nucula.
