 tion, proceeded to give an account of his explorations in 

 1891 in connection with the U. S. Fish Commission in the 

 Steamer "Albatross," commanded by Captain Z. L. Tanner. 



This expedition opeued the deep water of the Panamic Region as 

 far west as the Galapagos and as far north as the Gulf of California. 

 He compared the deep water Panamic fauna with the abyssal fauna of 

 the Caribbean, as well as the primal conditions of life existing in the 

 ocean on the two sides of the Isthmus. When contrastinw the coral 

 fauna of the two seas he took occasion to refer to his recent explora- 

 tions of the coral reefs of the Bahamas and of the Bermudas^ and to 

 indicate their bearing on the Darwinian theory of the formation of coral 

 reefs. The exploration of the Bahamas took place in the spring of 

 1893, in the Steam Yacht " Wild Duck," owned by the Hon. John M. 

 Forbes. That of the Bermudas was made in March, 1894.
