I have named the shell after my shipmate and friend, Lieutenant Tho- 

 mas Graves, wrhose zeal assiduity in assisting and increasing my collec- 

 tions of Natural History, was as unwearied as the alacrity and ability 

 which he displayed in the primary and more important objects of the 

 voyage, of which in His Majesty's Ship, Adventure, he filled the 

 appointment of Assistant Surveyor. To Lieutenant Graves I am prin- 

 cipally indebted for my land-shells, and I therefore take the opportunity 

 of recording the valuable assistance he rendered me during the whole 

 period of his serving under my command.
