tills specimen to be a new and hitherto unde scribed species of 

 fresh-water lamprey. I am promised the next specimen caught, 

 and I shall transmit to my old fellow-student at St. Bartholo-

 British Museum — as I am sure I could not submit it to* an 

 authority higher in general estimation than this world-famed 

 naturalist.
