MISCELLANEOUS. 
On Astarte excurrens and A. modesta, 
Lo the Editors of the Annals and Magazine of Natural History. 
GENTLEMEN,—In the paper upon the Mediterranean Mollusca, by 
Mr. Jeffreys, published in your Magazine for es of d present 
Which are there inserted as sti ing. 
I wish particularly to notice one of. these E as my Supplement 
to the Crag Mollusca gite preparation) ries made to en 
Zool. Soc. 1869, pl. 19. f. 14) ; and it is there said to be “allied to 
Astarte ewcurrens of Searles Wood, and possibly the same species.”

C. B. Adams. I have written to Mr. H. Adams for his ee and 
sent to him some Crag specimens of Astarte excurrens for compari-

is not only specifically distinct from the Crag one, but that it does 
not belong to the same genus. My Cra shell has an external liga- 
E 
oblique, running out at the margin from eac ng 
direction ; while the so- called Astarte modesta has an internal liga- 
ment and concentric ridges (i.e. ridges parallel to the margin), and 
belongs to the "gue. section of Crassatella of which C. B. Adams 
has made the genus Gouldia. 
I remain, Gentlemen, yours, &c.,

The tale of British land and freshwater shells is not yet told. 
dead specimen of Helix personata has been found by Mr. 8. A. 
Stewart, of Glasgow, at Newcastle, i in co. Down; and it is now, through 
his kindness, in my possession. Last yea r I examined Mr. Stewart’s 
collection of fossil shells from the Post-Tertiary beds at Belfast and 
in that neighbourhood ; and I have since received several communi-
