 on the banks, and never saw them dive or apparently catching 

 any tish, tliough they are often in company with boobies and dif- 

 ferent species of terns, all of which are actively employed in fish- 

 ing. About half way from Andros to the Bank I saw on the 

 2Gtli of April a Hock of boobies, sooty terns, noddies, Cabot's 

 tern, and the dusky petrel, that covered the surface of the water 

 or hovered over it for an extent of at least a square mile. Their 

 number must have been enormous.
