Art. V. — Notes on New Species of Microscopical Or-

 By LoRiNG W. Bailey. 



In the year 1854, the U. S. Exploring Expedition, under 

 the command of Capt. Lee, in the course of their cruise 

 in the brig Dol])hin, collected on the eastern coast of the 

 American continent a number of soundings and algae, 

 which were at that time submitted to my father. Prof. J. 

 W. Bailey, for microscopic examination. One locality, in 

 particular, the mouth of the Amazon and the River Para, 

 proved very rich in rare and new species of diatomaceous 

 and allied organisms. These were at once submitted to 

 careful study, and arrangements made for their speedy and 

 accurate publication. As far as I can learn, it was de- 

 signed that the description of these organisms should 

 accompany the Report of the " Cruise of the Dolphin " to 

 Congress, and two plates were prepared in outline for that 

 purpose. For some reason, which I have not been able 

 to trace, neither the plates nor the descriptions have ever 

 been published, and a few proof-copies in my possession 

 are all that remain of the original work. As most of the
