Pennant's British Zoology. 



The fourth edition of this work contains many new species of 

 mollusca, and as there may be trouble in connection with the 

 quotations cited, I have drawn up this note. 



In the Bibliography of the " Index Animalium ", 1758-1800, 

 Sherborn included — 



" Pennant, T. Brit. Zool. Ed. 4. 4 vols. 8vo. Warrington, 1776 

 and 1777. [In vol. 4 P. uses binominals.]" 



Upon referring to the copy in the British Museum (Natural 

 History), which was an octavo as cited by Sherborn, I found my 

 references did not agree with Sherborn's as given in the body of the 

 work. I then found there was also a quarto edition, and, strangely 

 enough, a copy of this had been examined by Sherborn in making 

 up his index. The page quotations entirely disagree, and I made out 

 a complete list of the new names from the Brit. Mus. 8vo edition, 

 and have collated them with a quarto copy kindly lent me by my 

 friend Mr. A. E. Salisbury. 



In the Catalogue of the Library of the British Museum (Natural 

 History) Mr. B. B. Woodward has carefully noted the two editions, 

 and in his synonymy of British Non- Marine Mollusca he tells me 

 he is carefully noting each reference. As the Library Catalogue 

 is not in the hands of every conchologist, I give here the pagination 

 of the principal entries. 



In the Journal of Conchology, vol. xiv, April, 1913, E. A. Smith 

 gave an account of the Pennant Collection of British Shells (pp. 38- 

 41), noting the types still extant, and now preserved in the British 

 Museum (Natural History). 



With regard to this fourth edition the frontispiece of vol. i is 

 headed " British Zoology. Class I Quadrupeds. London. Printed 

 forBenj. White, mdcclxxvi," while the title-page states : " British 

 Zoology. I Vol. i. I Class I. Quadrupeds. | II. Birds. | Fourth 

 Edition. | Warrington : | Printed by William Eyres, | for | Ben- 

 jamin White, at Horace's Head, Fleet-Street, London. | 



MDCCLXXVI." 



The Preface, covering eighteen pages, is dated Downing, 

 1st March, 1776. The titles of vols, ii and iii agree with different 

 classes indicated and without the words Fourth Edition. 



Salisbury's copy is interesting because in the first volume on the 

 back of p. xxix is a list of " Errata ", and then the words below : 

 " The Book -binder is requested to place the Plates according to the 

 numbers aSixed to the figures which refer to the descriptions," 

 and then there is a duplicate p. xxix with, on the back, a longer list 

 of " Errata " and " The Book-binder . . ." omitted. Then follows 

 " Plates to British Zoology. Vol. I Quarto ", and positions given. 

 At the end of vol. iii, on the back of p. 371, is a list of " Errata " 

 and the notice : "In May next will be published, British Zoology, 

 Class V, By Thomas Pennant Esq ; containing about Ninety
