COCCOTHRINAX Sp. 
A single leaf with the form and veination of С. Са’ (Chap- 
man) but somewhat less densely pubescent. Locality : New Provi- 
dence, Nassau, February 1890 (no. 284). 
Mr. Lyster H. Dewey, of the U. S. Department of Agriculture, 
recently brought back from New Providence Island a leaf probably 
belong to a Coccothrinax and popularly called *'silver thatch.” 
The leaves are commonly used for weaving into hats and baskets. 
The trunk seldom, if ever, exceeds about 2.5 m., and is about 15 
cm. thick. A photograph secured by Mr. Dewey shows that the 
surface is largely free from leaf-bases, and fairly smooth, the leaf- 
scars being but slightly impressed. The diameter seems to be 
rather uneven, with a tendency to become somewhat thicker in the 
middle. 
Paurotis gen. nov. 
A small, slender palm with spiny petioles like Copernicia, but 
with only the primary branches of the slender inflorescence sub- 
tended by spathes. 
Paurotis is probably more nearly related to Serenoa than to 
Copernicia, but differs in the larger size, the erect trunk, the 
stronger ligule, the absence of the ligule-like inferior scales, the 
presence of a rudimentary midrib, and in the more deeply divided 
segments. Inflorescence much more slender throughout than in 
Serenoa ; flowers much smaller, with free sepals and short, val- 
vate petals. 
The long, naked and apically scarious and bilabiate spathes 
are strikingly different from those of Copernicia. The inflorescence 
is much longer and more slender than that of Serenoa, but in other 
respects has greater resemblance than to that of Copernicia. The 
leaves, on the other hand, are more like Copernicia, though the 
presence of a true midrib, even if very small, with one or two seg- 
ments inserted somewhat above the base may be taken as a further 
sign of affinity with Serenoa. 
The present genus will probably accommodate the palm from 
Puerto Rico (5/шеліз, 6572) referred by Professor Drude to
