596 Verrill, JVotes on Hadiata. 



allies in the Caribbean, are represented in the Indo-Pacific fauna and 

 may be i-egarded as true Pacific types ; 7 species (including Ltitken's 

 new genus of star-fishes, not in the list) have no allies elsewhere, so 

 far as known, and for the present may be regarded as peculiar West- 

 American types. 



We may, therefore, consider this fauna as made up, approximately, 

 of 11 species, Atlantic in type; 9 Indo-Pacific; 19 cosmopolitan, and 

 4 others probably so ; with 6 species of types peculiar to the west coast.
