BE li MEDIAN DECAPOD FAUNA 



It is evident, therefore, that the Bermuda decapod 

 crustacean fauna is an offshoot or colony from the West 

 Indian fauna, with only a slight admixture of species 

 from other regions. In this respect the Crustacea agree 

 with the Anthozoa, Mollusca, Echinoderms, etc. 



The additions to the fauna of Bermuda, including the 

 new species and varieties, are as follows :
