TELLINA.

Testa altero latere inflexa. Cardo dentibus aliquot, raro lateralibus.

T. gargadia. T. antice rugosa, rima dentata.

The absurd "marginis posticum latus remotum" was a misprint for (dens) "marginis posticus, latus, remotus."

T. lingua-felis. T. subovata scabra.

"Klein, t. 11. f. 62" (cited in the 'Systema'), and "d'Arg. t. 25. f.G" (the description of which suits better than the drawing) are the additions of the MS.: "sesquilatiore" was the printed emendation of "latiore."

T. virgata. T. ovata, striis transversis retrorsum imbricatis, dentibus lateralibus.

The erroneous reference to d'Argenville was not present: "Klein, 158. Tellina virgata Rumphii" had been added by Linnæus. A very large portion of the printed account is wanting in the MS., to wit—"æquales. Intus radiis obsolete incarnatis picta." "Labris rugosis et scabris," "hymene tectis. Anus est rima concava," "primores," "transversi cum cavitate pro oppositis dentibus," "longitudinalem." The "retrorsum" was originally "sursum"; "dextrum" was "sinistram"; "Tertius dens" was "Altera testa."

T. gari. T. ovalis, striis transversis retrorsum imbricatis, dentibus lateralibus nullis.

The G in the reference to Rumphius, and the F in the reference to d'Argenville were misprints for D and I, and were so published in the 'Systema:' the "primoribus" was an emendation.

T. albida. T. ovalis, lævis, nymphis prominulis. "Primores" was an emendation. The species was unnamed.

T. foliacea. T. antice scabra, rima serrata.

The Rumphian name "folium" was the intended appellation: "Klein, 162. t. 11. f. 64" was cited, as in the 'Systema': "aciatum" was the reading for the printed "acutum."

T. planata. T. ovata plana, transversim striata, marginibus acutis.

The erroneous reference to Gualtieri (whose figure C looks more like the species than his G) is not to be found in the manuscript. The species was not named.

T. lævigata. T. ovata lævis, nymphis intractis.

The figure of T. chloroleuca in Rumphius was not quoted, neither was the hence-derived appellation attached: the "radiato" and "primoribus" were also subsequent additions.

T. radiata. T. ovali-oblonga, longitudinaliter substriata, sutura postica canaliculata. "Obsoletis" and "primores" were subsequent emendations.

T. rostrata. T. oblonga, antice angulato-rostrata.

The T. rostrata of the final edition of the 'Systema' was assuredly the T. Spengleri, and with that shell solely will the printed account in the 'Museum Ulricæ' accord. But the five earlier lines of the description (save "et albus"), and the detailed dentition (except "fossula distinctus"), with the varieties a, b, g, and the same synonyms as in the tenth edition of the 'Systema,' appear in the MS. with the name T. petasunculus attached. Whether designedly or not, there was a pictorial definition of T. vulsella in the earlier 'Systema;' and if an author be not allowed to amend his description, T. vulsella is better entitled than T. Spengleri to the name rostrata. "Margo exterior parum repandum est" was written in the MS.

T. remies. T. rugosa, suborbiculata.

The expressions "hians," "primores," "remoti," and the last five words of the details were absent; "utrinque" followed "duo": "non" in place of "vix" was the earlier reading.

T. scobinata. T. scabra orbiculata.

"Primores," and "in altera testa profunda fossula distinctus," were not in the copy.
