TO OUR SUBSCRIBERS. 
T N the present part, Lists of the Fossils of the various Land and Fresh- 
water Genera are given, arranged under the different formations in 
which they have been found. 
Criticism of these lists is cordially invited with a view to securing 
greater correctness and the more rigorous elimination of all species ex- 
clusively of estuarine or brackish-water habitat. 
Accurate and complete lists are especially desired in view of the 
intention to illustrate in succeeding parts every fossil species of our Land 
and Freshwater Shells.

“ I enclose a postal order — with thanks for Part VI. of your ‘ Monograph.’ It 
is .a really remarkable work of quite e.xceptional ability.” — I am, yours faithfully, 
Robert Roog Watson, LL.D.

“ The arrival of another part of your beautiful ‘ Monograph ’ reminds me that it 
is years ago since I heard from you. There is a good deal in these parts that was 
new to me, and they must have cost you an immemse amount of labour. — Yours 
sincerely, R. E. Scharff. 
Nore, Godalming, 19th June, 1900. 
“ Your Part VI. of the ‘ Monograph of the Land and Freshwater Mollusca of 
the British Isles reached me yesterdiiy, and I must express mj' admiration of the 
way in which you are bringing it out. The illustrations are beautifully done, and 
exemplify the diflerent parts of the animal .so truthfully it cannot fail to stimulate 
a little more interest in the beauty of the organization of the mollusca than exists 
at present among collectors.” — With best wishes, believe me, yours very truly, 
H. H. Godwin-Austen.
