SOME WEST INDIAN ECHINOIDS. 



23 



H. L. Clark, Doderlein, and myself; havinc^ to a consi<ierable extent altered the 

 specific conception of several Echinoids, besides pointin^^ out several cases of 

 incorrect identification. For the sake of comparison the list given in the Blake 

 Echini is reproduced beside the revised list, and references are given to the work 

 in which the corrections and additions are first pointed out. In the cases where only 

 the generic name has been changed such reference has not been thought necessary. 

 Several of the species have not of late years been reexamined; it is not 

 improbable that some further changes and atlditions will have to be made to 

 the list. The Clypeastrids especially might repay a careful revision.
