The letters '' P.O." I have attached to those Pennant definitely- 

 stated were in the Portland Cabinet, while the letters " B.M." have 

 been placed against those which Smith definitely recognized as the 

 figured specimens, now in the British Museum. As Smith observed, 

 probably many of the missing shells were figured from the cabinets 

 of other collectors, of which one instance is noted, i.e. of Pinna 

 ingens, which was in the collection of Dr. Walker, at Moffat. As 

 recorded in these Proceedings (Vol. XI, 1915, p. 333), Laskey wrote 

 concerning Voluta jonensis : " it is well known Pennant figured his 

 shell from this collection." 



An interesting case, comparable with the now historical one of 

 Helix nifescens Pennant (Ann. Mag. Nat. Hist., Ser. VIII, vol. xi, 

 pp. 263-4, 1913), is that of " Helix IcEvigatum ? " Pennant refers to 

 " Lin. Syst. 1250, No. 709." Linne's Helix Icevigata was described 

 from unknown habit, and no figure was cited, and has been rejected 

 as indeterminate. In the Conchological Society's List of British 

 Marine Mollusca, 2nd ed., 1902, No. 391, Pennant's name is used 

 as the basis of Velutina Icevigata, an extraordinary conclusion. If 

 Linne's name were unacceptable, Pennant's name was inutile, 

 but, moreover. Pennant's data reads " Inhabits ponds ", and the 

 figure seems to be that of a Lynincea, i.e. pereger. Further, before 

 Pennant's usage, 0. F. Miiller in the Zool. Dan. Prodr., 1776, p. 242, 

 had provided Bulla velutina based on a Danish shell for the Velutina, 

 and, consequently, the name would be Velutina velutina (0. F. 

 Miiller, 1776), and this is in accord with the usage of the best 

 continental workers. 



It may be as well noted here that " A New Edition " was published 

 in 1812 under the signature of " The Editor ". The identity of the 

 editor has been guessed at, so that it is important to record that the 

 proofs of this new edition are preserved in the British Museum 

 (Natural History) Library, and that the editor was Thos. Pennant's 

 son, David Pennant. This edition is also in four volumes, published 

 in London, and I have only seen it in octavo. 



The Mollusca occur in the fourth volume, and the whole of 

 Montagu's discoveries are included, as well as those of J. Adams 

 and other writers, but I have not noticed anything of novelty.
