MYA.
The three incongruous forms assorted as Myæ were not so united in the MS.; the second being very properly placed with the Mussels, the other two ascribed to Solen.
M. Lutraria. Sol. ovali-oblongus, cardine laterali dilatato semiorbiculato.
In lieu of the reference to Lister (whose work does not appear to have been consulted by our author at the period when this portion of his manuscript was written), plate 45, figure N, of Rumphius was quoted as illustrative. The published account of the hinge is much more complete than the written one, which was apparently drawn up from a worn specimen; it ran as follows: "Cardo extus vix gibbus, intus constans laminis 2 semiorbiculatis concavis introrsum spectantibus."
By a slip of the pen, in my "Ipsa Linnæi Conchylia," I had termed Brown's figure of the Linnean Mya lutraria, L. oblonga, instead of L. elliptica.
M. perna. Myt. lævis, cardine terminali unidentato.
The intended name was M. Magellanicus.
M. vulsella. Sol. oblongus, linguæformis, cardine terminali dilatato semiorbiculato.
"Pinna linguaformis subfalcata" was written after the reference to the 'Museum Tessinianum;' hence it seems that Linnæus did not himself consider that he had used the binomial method in that work, or he would have quoted it as P. lingulata.
"Rumph. 148. t. 46. f.a," and "Gualt. t. 90. f.h," were the unpublished synonyms.
