I was accompanied by six students, was made to Provincetown.

Grand Manan in the month of July. 
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 
Medusz collected by the Lady Franklin Bay Expedition, and a pre- 
liminary account of the Medusz 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.
