304 THE DOLABELLINAE. 



The genus Dolabella so far as is known is confined to the Indo-Pacific 

 area, ranging westward to the Red Sea and the Cape of Good Hope, eastward 

 to the Gulf of California, the West coast of Mexico and the Gulf of Guayaquil, 

 and southward to New South Wales. Quite a number of species have been 

 described, most of them in an incomplete manner, and all are in need of careful 

 detailed study and revision. Pending this the following chronological list 

 includes all apparently vaUd species, though some of them may be found later 

 to be but varieties of a few widely distributed forms.
