Ellipsolites Compressus, J. Sowerby (Min. Con. vol. i. p. 84, pi. xxxviii. 1813), has been hitherto usually regarded as a Nautiloid,1 and referred either to Nautilus or to-Discites.
During an examination of the collection of Mr. Joseph Wright, of Belfast, by one of the present writers, a fossil from the same horizon, and almost the same locality as the type-specimens of Ellipsolites compressus of J. Sowerby, was observed, so much resembling Sowerby's species (but exhibiting also the character of the suture-line) that a comparison with, and a re-examination of, Sowerby's types was suggested.
