In the list I have prefixed letters to indicate the relations of this to 

 the other tropical fauna'. Those species indicated by c are represen- 

 ted by closely allies species in the Caribbean fauna; those designated 

 by M are represented in the same way in the Mediterranean ; those 

 with A have corresponding species on the west coast of Africa; those 

 with I have representative species in the Indo-Pacific fauna. 



The species which I have personally examined are designated by a 

 mark of exclamation (!).
