branchio-gastric ganglion in fishes, and as well as the nerves 
which have been already described, will serve to indicate the 1m-

[Berne unable to find room for Mr. Buckley’s detailed account 
of a botanical tour through the mountains of Alabama, Georgia, 
Tennessee, and Carolina, we have, in accordance with his re- 
quest, merely extracted the description of new species for present 
publication. We also append, ina note, the diagnostic character 
of a new genus of Santalacez, established by Dr. Torrey, upon 
materials chiefly furnished by Mr. Buckley, to whom it is dedi- 
cated ; a full account and figure of which will hereafter be given 
in this Journal.*—Ebs. | 
STREPTOPUS MACULATUS (7. sp.): stem and nerves of the lower 
surface of the leaves minutely pubescent ; leaves sessile, ovate- 
lanceolate, acuminate ; pedicels generally in pairs at the summit 
of the branches, not distorted ; sepals subspatulate, acuminate, 
yellowish-white with numerous purple spots, rather longer than 
the filaments; anthers oblong; style longer than the stamens ; 
stigma short.
