212 PROCEEDINGS COTTESWOLD CLUB 1906 
this issue was published at Edinburgh, and bears date 
1834. 
Since the above was written Mr C. D. Sherborn has 
kindly given me a copy of his recent pamphlet on “ The 
Conchological Writings of Capt. Thomas Brown” (Proc. 
Malacol. Soc. vi, 358, 1905). From this it can be seen that 
the Fossil Conchology began in 1837 and ended 1849 ; and 
that pp. 117 to 136 were issued in 1845. Therefore p. 
138 containing 7. acuta-plicata would be about 1845 or 
1846; but exact dates after p. 136 are not yet available. 
Mr Sherborn notices that practically nothing is known 
about the life of Thomas Brown—not enough for mention 
to be made of him in the Dictionary of National Biography. 
Mr Sherborn “ will welcome further information.”
