SEVERAL years ago I received from Mr. John Harker, of Rich-

and a few organisms picked out, mounted on slips, and marked,

Shells, on which were incrusting Fenestella and Berenicea. Many 
of the specimens mounted on the slips were duplicates, and as 
near as I can remember they were collected together from the 
neighbourhood of Richmond and Hurst. Mr. Harker was de-

Carboniferious series ; and besides these, he very wisely mounted 
and preserved other organisms as well. Always in very delicate 
health, our correspondence was cut short by his death, and the 
exact localities of his specimens are thereby lost, for since his death 
his collection has been scattered abroad. I tried to purchase his slips 
of Polyzoa, but I never had an answer to my offer, and thus this
