ACALEPHS. 



By Henry B. Bigelow. 



The most important accession received during the year is the 

 collection made by Mr. Agassiz on his expedition to the West 

 Indies on the steam yacht " Virginia." This material contains 

 many genera both of Medusae and Siphonophorae previously un- 

 represented in the Museum. The following gifts have been 

 received : from Mr. Thomas Barbour, Olindias and two genera 

 of rhizostomes from the Dutch East Indies ; from Dr. John 

 Bryant, Jr., Lucernaria from Labrador, Mr. Owen Bryant, several 

 specimens each of Sarsia, Cyanea arctica, and Mertensia ovum 

 from Newfoundland ; from Dr. H. L. Clark, Haliclystus, and 

 cotypes of Charybdea xaymacana, and Tripedalia eystophora 

 Conant, from Jamaica ; from Professor G. H. Parker, Gonionemus 

 murbachi, and several specimens of Aequorea tenuis from Woods 

 Hole. The Assistant, also, has collected specimens of Sarsia, 

 Melicertum, and Aurelia. 



From February until April, 1907 I accompanied Mr. Agassiz as 

 one of his Assistants on his expedition to the West Indies. The 

 remainder of the year I have devoted chiefly to my report on 

 the Medusae collected by the expedition of the " Albatross" to the 

 Eastern Tropical Pacific in 1904-05.
