INDEX 



The following index contains the names of the orders, familiei", genera, species, and mibspeciea of 

 Asteroidea which occur in this memoir. Two kinds of type are used for the namec, roman and iulic; 

 the former indicates valid names, the latter synonyms. But when a species name follows a penus name 

 that is a synonym of another genua name, both the genus and species names of the combination are iuli- 

 cized, although the species name may be valid. Two kinds of type are used in the figures referring to 

 the pages; the heavy-faced typo indicates the pages on which descriptions may be found. The names 

 occurring in the explanation of plates have not been indexed, as the easiest method of finding all the 

 figtires of a given species is to turn to the page on which the description occurs, where a list of figures ia 

 indicated.
