Dolium, Cassis, Nassa, Triton. The uumber 1 — 4 are the same 

 as in tlie notes; the three spccies then following have discre- 

 pant and lower numbers, from several having been omitted. 



Turbo. Twelve speeies, all cxotic and in the M. L. U. 

 Xine of them are marked in the pencil-notes not with num- 

 bers bnt witli trivial uames, most of which werc adoptcd in 

 S. N. ed. 10, as: marmorens, petholatus, delphinus, calcar. 

 Others, as os aureum for chrysostomiis, teetum chinense for 

 pagodiis, are found also in the Lectures. 



Trochus. Fivc speeies, all exotic and in the M. L. U. 

 Only two of them are in the notes, with numbers not con- 

 gruent. 



Nerita. Ten speeies: eight, exotic, in the M. L. U., with 

 N. littoralis and X. fluviatilis of the S. X. Last comes »10 

 vitellum, the yolk, from its form and yellow colour: Xerita 

 edentula umbilicata labio supra iimbilicum explanato». Only 

 one speeies is among the seven noted in Rumphius. 



BucciNUM. In the pencil-notes as well as in the Hanley 

 MS the B. perdix, B. olearium?, B. dolium, B. pomiim, are 

 marked Buecinum. In the Lecture they are omitted and »1. 

 Harpa nobilis», »2. B. persicum», marked in the notes: Lyra 

 1 and Lyra 3, the only two exotic speeies mentioned. The 

 third speeies is B. undatum followed by Murex despectus. 

 »Among the speeies of the Fauna Svecica» (ed. 1) »the folloAving 

 are Buccina>: »lo02» (Bulla fontinalis of Fn. Svec. ed. 2) »the 

 only one that lives on land»; »1310 — 11, 1315 — 16 (Helix stag- 

 nalis, H. fragilis, H. auricularia, H. balthica, ib.) and 1317 

 (Helix putris ib.) are fresh-water speeies». »The following 

 species« (of the Fn. Svec. cd. 1. besides these) .>are marine: 

 1321, 1322, 1323, 1324» (B. lapillus, Turbo terebra, Strombus 

 pes pelicani, Xerita glaucina Fn. Svec. ed. 2). It is scen that 

 while the other genera of Testacea contain for the most part only 

 exotic speeies, Linn.eus here mentions very briefly those of 

 Buecinum, and, conforming mostly to Lister, takes the oppor- 

 tunity instead to point out summarily the indigenous speeies, 

 for that end at the same time reinovinor the cenus from its 

 proper position, and taking it up between Xerita, wliere two 

 Swedish speeies are already introdiiced, and Helix. For the 

 same purpose, in order to bring close together all the spe- 

 eies then known to him of Swedish Gastropoda, he gives
