CAPE VERDE MARINE FAUNA.

examination of several large collections simultaneously by a worker 

 (or group of workers) who has seen the specimens alive. 



The fauna of the Cape Verde Islands also promises to be 

 interesting in connection with the ocean- currents of the Atlantic. 

 The group (text-fig. 21) lies in the path of the southern division 

 of the Gulf -stream, which is joined by another stream from near 

 the Sfa^aits of Gibraltar. Both these are cold currents, the Avarm 

 stream from the Gulf of Guinea passing a little to the south of the 

 group. It will be interesting to know what constituents of the 

 fauna, if any, are derived from the Caribbean Sea. Some ISTorth 

 Atlantic and Mediterranean forms are mentioned below.

For the purpose of a comparison of faunas, the common forms 

 of life in a few groups are sufiicient, and a summer vacation 

 affords time enougli to collect these. I therefore applied to the 

 Carnegie Trustees for funds to enable me to spend two months in 

 the Islands, which they generously supplied. The kindness of 

 many friends at home and in the Islands made my stay most 

 pleasant, besides contributing much to the success of my work. 

 I cannot publicly thank all by name, but to Messrs. Rhodes and 

 Pacey, Managers of Messrs. Wilson's Coaling Company, I owe 

 special gratitude for the use of a room in their house as a head- 

 quarters' laboratory — a boon the vahie of which the donors 

 themselves could hardly fully estimate.
