* 
very easily separable, and only differ from those of Paypayrola* in 
being shorter, the staminal apparatus is precisely that of the latter 
genus. The berry and seeds cannot be distinguished from those of 
other baecate Violacee. Specimens indeed in fruit of Leonia cymosa, 
from Mr. Spruce's Barra collection of last year, appeared to me so 
evidently Violaceous, that I distributed them under the name of 4m- 
phirrhoz? sp. n., the absence of flowers preventing my recognizing 
them as belonging to Leonia, which I did not then possess. The 
flowering specimens now received, were, like those in fruit, gathered in 
the Capoeiras and shady forests about Barra do Rio Negro, and will 
be included in the distribution now going forward.

Ringgold’s United States Scientific Exploring and Surveying Expedition. 
(From the * New York Journal of Commerce.) 
This expedition consists of five vessels under the command of Com- 
mander Cadwalader Ringgold, which have been equipped, rigged, and 
manned with a view to the peculiar service for which they are designed ; 
a service of the utmost importance, not only to our country, but to the 
entire world, as it is intended to examine and survey a large portion of 
the North Pacific Ocean, Behring’s Straits, and the Arctic Sea, so far 
north as may be found practicable, together with the adjacent coasts of 
America and Asia,—these surveys having for their object the promotion 
of commerce and of the whaling business in those greatly frequented, 
but slightly known regions. The various groups of islands lying in the 
track of the shipping trading on the North Pacific are to be visited and 
accurately surveyed, and the Chinese, Sooloo, and Celebean seas, with 
their numerous islands, straits, and harbours, which are now either 
unknown, or very imperfectly ascertained and located, and through 
which hundreds of our vessels will be trading with the East Indies, are

vii. p. 368. My genus Periclistia, Hook. Journ. Bot. vol. iv. p. 108, must be re- 
duced to Paypayrola. I had been misled by the errors in Aublet's drawing, now 
corrected by Tulasne. Hs face
