The following list of mollascan species so far identified is pre- 

 ■sented by the second author. It is hoped that it will be supple- 

 mented later in the reports of the specialists now engaged in 

 working up the Crustacea, Echinodermata, Annelida, Tunicata 

 and Actinians. It is for this reason that specific names in these 

 groups have been so seldom given in the text.
