A FURTHER REPORT ON THE OSTRACODA OF 

 UNITED STATES NATIONAL MUSEUM.

By Richard W. Sharpe,

In a previous paper bearing a similar title " a number of species of 

 fresh-water Ostracoda belonging to the U. S. National Museum were 

 briefly discussed, and two presumably new species described. Mosi 

 of these forms were from scattered localities in the United States 

 and Mexico, and represented the known ostracod fauna of these 

 countries but meagerly. Since that paper was published, a number 

 of marine as well as fresh-water forms have come to my hands for 

 study. The marine forms were mostly collected by the U. S. Fish- 

 eries steamer Albatross. 



It therefore remains for me to give an account of these forms, and 

 the present paper offers some results. Four species, apparently new 

 to science, are here figured and described. It also seems wise to 

 insert a revised systematic summary, indicating the extent of the 

 National Museum collections examined to date of this paper.
