VoLUTA. This name, from Rumphius, is used for Mdiat soon 

 became, or rather already was, Conns, which is adopted in the 

 pencil-notes with the exception of a single species, marked 

 Voluta 4, the >Grau\ve Mimnikin of Kumphius, t. XXXIII, f. 

 (7(7, the C. monachus of the M. L. U. and the S. N. ed. 10. 

 Nineteen species. The nixmbers 3, 4, 5, 7, 8, 9, 14, 19, answer 

 to 3, 5, 6, 10, 11, 12, 20, 25 of the pencil-notes, exactly as 

 if the arrangement had been the same on both sides, and the 

 species given in the Lectiire had been picked out from the 

 larger number in the Queen's collection. The order is entirely 

 difFerent from that in the S. N. ed. 10 and the M. L. U. 



Cylindrus. Name from Bonanni, in the pencil-notes and 

 the Hanley ]VIS called throiighout by its future and final

 U., M. brandaris and one not identified. The numbers 1 — 4

 aruanus and trapezium of S. N. ed. 10 are marked Strombus 

 11 and 7, while ]\I. babylonius, vertagus, aluco, are marked 

 Turricula 13, 6 and 9. Both these genera as it will seem nu- 

 merous in species, and not mentioned in the Lectures, were after- 

 wards dropped ^), and the name Strombus substituted for Har-

Harpago. Name from d'Argenville, p. 288, adopted also 

 in the pencil-notes and the Hanley' MS, exchanged in the S. 

 N. ed. 10 for Strombus, from Bonanjji. Thirteen species, all 

 in the M. L. U. The numbers 1^ — 4 re present the same species 

 as in the notes; then follow live others marked with deviating, 

 always lower numbers. cleariv indicatino- their beino- selected 

 from the larger list. 



Cassida. Xame from Lang, 1722, adopted in the notes
