ACALEPHS. 



By Henry B. Bigelow. 



The most important accession is the series, from the U. S. Bu- 

 reau of Fisheries, of the Medusae (Craspedotae and Acraspedae) 

 collected during the expedition of the " Albatross" to the Eastern 

 Tropical Pacific, 1904-1905. Of the sixty-four species, many rep-
