Report on the Actiniaria Collected by the 

 Bahama Expedition of the State Uni- 

 versity of Iowa, 189?. 



By Dr. J. PLAYFAIR McMURRTCH. 



The chief interest of this collection, the examination of 

 which I undertook at the request of Professor Nutting, lies in 

 the number of deep water forms which it contains. Certain 

 of these have been previously described, and I have been able 

 to add to the earlier descriptions of these additional facts which, 

 it is hoped, will render them more complete; but besides these, 

 a number of apparently undescribed forms were found, some 

 of which possessed considerable interest. 



The littoral forms were not as abundantly represented as I 

 had expected, but I found especial interest in a species of 

 Adamsia. the study of which seemed to clear up the synonomy 

 of the described American species of that group. My friend, 

 Mr. J. E. Duerden, Curator of the Museum of the Institute of 

 Jamaica has kindly answered many inquiries concerning some 

 of these littoral forms and has sent me specimens for compari- 

 son; for these kindnesses I am under great obligations and it 

 gives me much pleasure to make public acknowledgment of 

 my indebtedness.
