The Museum has published for me in its Bulletin a preliminary 

 account of my observations on the development of Ophiopholis and 

 Echinarachnius. There have also been published a report on the 

 Medusae collected by the Lady Franklin Bay Expedition, and a pre- 

 liminary account of the Medusae found by the United States Fish 

 Commission steamer " Albatross." The former will be found in 

 an Appendix to Lieut. Greely's book on his Arctic experiences ; 

 the latter, in the Report of the Fish Commission for 1884.
