48 MR.S.HAl^LEY ON THE LTNNEAN MS. OF THE 'MUSEUM ULRICA.' 



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 pubHshed in the 

 * Systema :' the '* primoribus " was an emendation. 



T. ALBiDA. T. ovalis, Isevis, nymphis prominulis. "Primores" wa^ 

 an emendation. The species was unnamed. 

 T. FOLIAGE A. T. antice scabra, rima serrata. 



The Ruraphian name " fohum " was the intended appellation : " Klein, 

 162. t. 11. f. 64" w^as cited, as in the ' Systema' : "aciatum" was the 

 reading for the printed " acutum." 



T. PLANATA. T. ovata plana, transversira 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. L^viGATA. T. ovata lajvis, 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 pos- 

 tica canaliculata. "Obsoletis" and " primores " w ere subsequent emen- 

 dations. 



T. RO ST RATA. 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 Ulricae ' 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 oXtuchedL. 

 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. "Mavgo 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. 



CARDIUM. 



Cardo dentibus baseos binis, marginis solitariis remotis acutis. Val- 

 vula3 gibbae, hinc figura cordis. 



BucARDiUM was the epithet apphed in the written copy to the members 

 of this genus, to which the Solen bullatus of the ' Systema ' was correctly 

 referred. Mactra had not then been separated.
