Family SCARIDAE 



My material of this family is not very extensive, and since the life 

 colors have faded it is not possible to identify some of the specimens 

 with any degi'ees of certainty. I am listing those from the Phoenix 

 and Samoan Islands mostly as studied by Jordan and Scale and later 

 by Fowler, except where I do not agree with them.
