82 MB.S.HANLEY ON THE LINNEAN MS. OF THE 'MUSEUM ULraC;E.' 



Neither "aenmiuata", nor the inappropriate " rotundata", were in the 

 original acconnt of this well-known species. 



T. CALCAR. T. exumbilicatus depressus, anfractibns supra spinis for- 

 nicato-compressis scabris. 



To his printed synonyms Linnaeus has added " Gualt. t. 65. f. N. P.", 

 " List. Hist. t. 608. f. 46", and "Klein t. 1. f. 27". The "fornicatis" 

 was an emendation. 



T. MARMORATUS. T. exumbiUcatus subovatus nodosus laevis. 

 T. PICA. T. umbilicatus laevis conicus denticulo umbilicali. 

 " Habitat in Barbados, Jamaica", which corrects the stated locality of 

 the ' Systema,' and " Bonan. 29, 30", "Pet. Ga^. t. 70. f. 9", were the 

 additional particulars of the manuscript copy. 



T. ARGYROSTOMUS. T. umbilicatus subovatus, striatus lineis dorsalibus. 

 The erroneous references to Gualtieri and d'Argeuville, were not present : 

 " OS argenteum variegatum " was written after the reference to Rumphius, 

 which name belongs to figure 3, not to 4, whose colouring, moreover, ex- 

 cludes it from being illustrative. The intended specific name was " os 

 variegatum." 



T. MARGARiTACEUS. T. cxumbiUcatus subovatus, (? angulo) dorsali 

 elevato, ore postice diducto. 



Rumphius was not referred to in the original, where " subtilissimis " 

 was in the place of " variis " : the printed " margine albo " was a subsequent 

 emendation. 

 T. DELPHiNUS. T. umbilicatus depressus hispidus, spinis ramosis. 

 " Pet. Amb. t. 3. f. 1 ", and "Grew Mus. t. 11. f. 5, 6", wei-e also cited. 

 T. DiSTORTUS. T. umbilicatus muricatus undique spinulis brevibus. 

 The final remark was not in the original. 



T. scALARis. T. cancellatus conicus, anfractibus distantibus. 

 " Pretium immensum, ssepe 100 ducatorum", was the final remark in- 

 stead of the printed one. " Pet. Amb. t. 2. f. 9 ", was an additional 

 synonym in the written version. 



T. CLATHRUS. T. cancellatus pyramidatus, anfractibus contiguis Isevibus. 



All the synonyms of the tenth edition of the ' Systema,' together with 



" Johnst. t. 1 1, f. 9 ", were present in the MS., but most of them, together 



with the final remark, had been subsequently added to the copy by our author. 



T. CRENATUS. T. cancellatus pyramidatus, anfractibus contiguis supra 



crenatis. 



The details of the ' Museum ' were referred to before their publication. 

 " Pyramidalis " was the earlier reading for " turrita" ; " ssepe " was absent : 

 " transversim " preceded " crenati." 



T. UVA. T. cancellatus ovatus, anfractibus contiguis imbricatis. 

 " Pet. Gaz. t. 27. f. 2. Olivaris " was the unpublished additional syn- 

 onym, and the intended name was borrowed from that work. " Longitu- 

 dinalibus " was " transversis " in the copy, where " ut latus planum non 

 conspiciatur exterius distincta linea " terminated the account of the volu- 

 tions : the colouring ("alba") was not indicated.
