ART. = oe LINDHEIMERIANJE; AN ENUMERATION OF 
THE ANTS COLLECTED IN TEXAS, AND DISTRIBUTED TO 
mel , BY F. LINDHEIMER, WITH REMARKS, AND DE. 
SCRIPTIONS ni NEW SPECIES, &. By Gzonge ENGELMANN and 
Asa Gray. A 
Mz. LinpuemeER’s plan for exploring the botany of Texas, 
and preparing specimens of dried plants for distribution, was 
announced in Silliman’s Journal for July, 1843.. The collec- 
tion of that season, owing to various misfortunes, having been 
much smaller than was anticipated, it was thought best to 
defer its distribution until that for the year 1844 should 
come to hand. A part of the second collection was Jost in 
the course of transmission to St. Louis; those which were 
received in sufficient quantity for distribution extend the 
number to 318. Mr, Lindheimer is now entering upon an 
unexplored field west of the Colorado River, and we may 
confidently, expect that a rich harvest of peculiar plants W will 
reward his efforts during the present season. This collection 
will be assorted and distributed without delay, and our ac- 
count of them duly published in the pages of this journal. 
The collection of 1843 was made on Galveston Island, 
around Houston, on the Brazos, &c. The series commences 
with some species of Ranuncutus, allied to R. pusillus, 
which, having been long since distinguished by Dr. Engel- 
‘mann, and communicated to various botanists under the 
following names, the pr adi as assigned by him are here 
given.
