ACALEPHS. 



By Henry B. Bigelgw. 



During the past year an unusual number of accessions in this 

 Department has been received. The most important is the 

 duplicate set of siphonophores collected by H. M. S. "Research" 

 in the Bay of Biscay in 1900. These specimens received through 

 Mr. G. H. Fowler add many species, several represented by large 

 series, to the Museum collection. Noteworthy also are two large 

 and excellently preserved collections of Medusae, one from the 

 Philippine Bureau of Science, the other from Puget Sound, from 

 the University of Washington through Professor T. Kincaid. 

 Specimens have also been given by Dr. A. G. Mayer, Mr. Thomas 

 Barbour, and Mr. Howard J. Shannon. A small collection of 

 Medusae has been received from the Berlin Museum in exchange. 

 Purchases for the year are series of Medusae, hydroids, siphono- 

 phores and ctenophores from Naples and from Woods Hole, Mass., 

 part of which have been placed on exhibition; also a specimen of 

 Rhopilema verrillii Fewkes collected at Branford, Connecticut, by 

 Professor A. E. Verrill. The "Albatross" collections of Hydro- 

 medusae made in the Philippines, and the Medusae, siphonophores 

 and ctenophores collected in the Northwestern Pacific, have been 

 received for study. 



During the year I have been occupied with the reports on the 

 siphonophores of the "Albatross" Eastern Pacific, and of the 

 "Research" Biscayan Expeditions.
