M. femorale. M. angulato-triqueter: angulis antrorsum acuminatis.
The intended name was M. triqueter. Grew's engravings (f. 7, 8) of the species were correctly cited, and the erroneous reference to Rumphius was not inserted. The printed additions were unimportant—"exarata", "repando", "sub" before "edentula", and "levissime".
M. lotorium. M. angulatus, tuberculis conicis, cauda flexuosa, labio interno rugoso.
"Subter" was a misprint for the written "inter": the "ut in proximis" was a printed addition.
M. rubecula. M. angulatus, sulcis moniliformibus, costis lateralibus, dorsalique.
"Gualt. t. 49. f. 1" was rightly cited as illustrative: "ex" preceded "lineis".
M. reticularis. Cas. inæqualis gibba reticulata, cauda elongata.
The erroneous reference to Rumphius was not present in the manuscript. As corroborative of my expressed belief in the identity of the species described in the 'Museum' with the Triton ! mulus, it may be observed, that our author has wholly separated this and the allied anus from the true Tritons and Ranellæ, and that the original heading corresponds accurately with the peculiar characteristics.
M. anus. Cas. inæqualis, gibba nodosa, labris rugosis.
"Pet. Gaz. t. 74. f. 9" and "Pet. Amb. t. 6. f. 4" were the unprinted synonyms. The "rugis reticulato-intertextis", "irregularis", and "patens" were emendations.
