MR. S. HANLEY ON THE LINNEAN MS. OF THE ' MUSEUM ULBIC^.' 51 



D. scoRTUM was wisely omitted. 



D. PUBESCENS. Trun. antice spiuis ciliatus. 



D. RUGOSA. Trun. antice rugosus, marginibus crenatis. 



The printed " cuneiformis " has replaced the earlier " majuscula" ; and 

 " crenulatis " was originally " undulatis." " Intus subviolacea est " was 

 not in the written copy. 



D. TRUNCULUS. Trun. antice laevis, marginibus crenatis. 



The reference to Klein was not in the original, but " d'Arg. t. 25. f. L." 

 was quoted (as in the twelfth edition of the ' Sy sterna '). The last seven 

 words printed were not in the copy. The intended name was gibbus. 



D. CUNEATA. Trun. cuneiformis, marginibus integerrimis. 



The final remark was not in the copy, where " parva, ovata," preceded 

 "cuneiformis." The then unpublished details were quoted in the 

 * Systema.' 



D. scRiPTA. Trun. ovatus Isevis scriptus. 



The erroneous citation of Gualtieri (a misprint for 88. f. Q.) was not in 

 the copy, and, as the figure represents the D. trunculus in the page opposite, 

 I suspect was carelessly placed here by the printer, when our author had 

 inserted it in his revised proof. I suspect this error often occurred, as for 

 instance in Tellina planata and radiuta, where Gualtieri's figure (added 

 diu-ing revision) was attached to the former instead of to the latter. 

 " Margo interne crenulatus," and nearly the entire account of the teeth, 

 were emendations. 



D. MURICATA. Trun. ovatus, striis muricatis, margine denticulato. 



" Postice soUtarii " followed the final " utrinque " : " primores " was 

 an emendation. 



VENUS. 



This genus (as a whole) was not to be found in the manuscript System. 

 Its components were distributed into three groups, two of which bore 

 names that were subsequently allotted to forms very remote from those 

 therein so designated. 



CuNNUS. Testa subrotunda. Rima nymphis instructa, Dentes car- 

 dinis 4, lateralibus divaricatis versus latera. This contained the bulk of 

 the Veneres, all except Nos. 63, ^&, and those referred to Pholas and 

 Chama. 



Pholas. Testa lenticularis. Rima fissa, destituta nymphis. Dentes 

 cardinis 1 s. 2, marginaUs tantum intra anum. V. Pennsylvanica, iiicrus- 

 tata, punctata, edentula, exoleta, scripta, pectinata, ziczac were its con- 

 stituents. 



Chama. Testa ovalis cum angulo. Cardo dentibus 4 confertis, quo- 

 rum unus in singula valvula bifidus. In this were located V. literata, 

 rotundata, decussata. 



V DioNE. Cun. cordatus, antice pubescenti-spinosus. 



The same references to Petiver, Olearius, and Lister were present as in 

 the ' Systema.' The final remark was an addition. The proposed name 



was C. Veneris.
