Clarke one on the Hydroids, with three plates. The illustrations 

 of these papers are in the hands of the lithographer. 



Mr. Scudder's Report on the Orthoptera of the Galapagos (three 

 plates) has been issued, and a short Bulletin on the Rocks of the 

 Galapagos has been published by Mr. George R Merrill. 



Excellent progress is also reported by Professor Hoyle, Dr. 

 G. W. Miiller, Dr. Ward, Dr. Bergh, Mr. Garman, and Professor 

 Studer with regard to the various collections intrusted to their 

 care. Professor H. V. Wilson spent some time at the Museum in 

 examining our collection of Sponges, in preparation for his report 

 on the Sponges of the " Albatross " expedition. 



Owing to my prolonged absences from Cambridge, I have my- 

 self made little progress with the groups which I had selected to 

 work up ; but I hope during the coming year to be able to devote 

 some time to them, and also to take up for publication the large 

 amount of material on the Acalephs of the East Coast of the 

 United States now in my hands. For nearly thirty years since 

 the publication of the Catalogue of North American Acalephs, I 

 have every summer, and frequently during the winter months 

 also, paid a good deal of attention to the Jelly-Fishes of our coast. 

 An immense amount of drawings and of undigested notes have 

 thus accumulated. Their publication, as well as a revision of the 

 papers on the same subject issued up to the present time in the 

 Museum publications and elsewhere, would form an instructive 

 and connected account of the Acalephian Fauna of our shores. 



For a complete list of the Publications of the Museum I would 

 refer to Appendix A. Of the Bulletin we have issued during 

 the past academic year four numbers of Volume XVI. of 

 the Geological Series, three numbers of Volume XXIII., com- 

 pleting the volume, and the whole of Volume XXIV. Of the 

 Memoirs, we have issued No. 3 of Volume XIV., completing 

 the volume. 



About the usual number of volumes have been added to the 

 Library, either by gift, exchange, or purchase. The number of 

 volumes is now over twenty-three thousand. 



As far as the available stock permitted, we have distributed a 

 number of more or less complete sets of our publications to insti- 

 tutions and societies with which we have only lately begun to 

 exchange. It has now become impossible for us to supply com- 

 plete sets of our publications. Many parts of the earlier volumes
