Fauna. 



In the preceding article 78 species, subspecies, or named varieties, 

 have been discussed, of which 16 have not been previously recorded 

 from Bermuda. Among these, 9 are described as new. 



Of the total number, 72, equal to 93 per cent., have been recorded 

 also from the Florida Keys or the West Indies, or from both, demon- 

 strating the close faunal relations of the two regions. The raacruran 

 Decapoda and other groups show similar relations.* 



About 53 of the forms (about 68 per cent.) range from Florida to
