4, “ Tllustrations of the Fossil Conchology of Great Britain and 
Ireland.” London, 1849 (i.e. 1837-1849). 4to; pp. 273, 98 pls. 
4a. ‘Illustrations of the Fossil Conchology of Great Britain and 
Treland.”” Edinburgh, 1834. 4to; parts 1-12. (Engelmann.) 
4b. ‘Fossil Conchology of Britain and Ireland.”’ London, 1839. 4to. 
5. 
25 numbers, of which 1—14 were issued by Messrs. Smith, Elder, 
and Co. in 1839. (Engelmann.) 
We can take these three entries together: 4 is the correct one, 
4a seems to be an error of Engelmann’s, 46 seems to be a muddle. 
In Mr. Sykes’ Library and also in the British Museum are pre- 
served a series of numbers in the original wrappers. From them 
we learn the collation which follows :— 
No. Pages. Date. No. Pages. Date. 
1 1-4 16 65-68 
2 5-8 17, 18 69-80

The numbers in the British Museum were most of them dated in 
pencil as received, the year coming first, then the month, then 
the day, then the press-mark, but more exact information being 
forthcoming by the kindness of Messrs. Smith, Elder, & Co., 
I shall give that. Moreover, it appears that Nos. 1-12 were 
published in Edinburgh, and sent to Messrs. Smith, Elder, & Co. 
for sale, while the later numbers were published in London by 
Messrs. Smith, Elder, & Co. themselves. They write me under 
date May 30th, 1905: ‘** Fossil Conchology’ extended to 35 parts, 
of which parts 1-8 were received in 1837, parts 9-12 in 1838, 
parts 13 and 14 in 1889, and parts 25 to 28 in 1845.” To 
these I can add, No. 15 received by the British Museum 
March 6th, 1843, No. 21 on November 17th, 1843, Nos. 22 and 
23 on July 9th, 1844, Nos. 24 and 25 on April 18th, 1845. 
The dates affixed to the parts given above are therefore approxi- 
mately correct, and we must wait further evidence before being 
able to define them more exactly. At page 53 the setting of the 
type slightly alters. In the ‘Elem. Foss. Conch.,” 1843, the 
advertisement says—‘‘to be completed in 26 parts, of which 22 
are out.”
