Copernicia, but having no spathes on the branches. Grisebach 
and Wendland described from Cuba, Copernicia Wrightii, which 
may also belong to Paurotis. 
Hitherto Copernicia has been the only known West Indian 
genus of fan-palms with spiny petioles. Тһе type of Cofernicia 
is C. cerifera (Arruda) from Brazil, but the Cuban species of the 
genus seem to resemble Paurotis even less than the Brazilian, 
since they have the inflorescence more robust and compact and the 
spathes more strongly developed. Тһе species listed by the 7»dex 
Kewensis ав Copernicia maritima (Corypha maritima H.B.K.) and 
Copernicia pumos (Corypha pumos H.B.K.) have smooth petioles 
according to the original descriptions, and should have been trans- 
fered to Thrinax rather than to Copernicia. Although treated as 
a synonym of Copernicia іп the /идех Kewensis the generic name 
Cryosophila Blume had priority of publication, as shown by the 
fact that it is cited by Martius in connection with the orginal de- 
scription of Copernicia. И seems probable, however, that Cryso- 
Phila is distinct from Copernicia as indicated by Drude. Its type, 
C. nana (H.B.K.), came from the region of Acapulco, Mexico. 
The petiole is unarmed and other characters are quite at variance 
with those of Paurotis. 
Paurotis Androsana sp. nov. 
Trunk 3 to 4 m. high, very slender, 5 to 6.5 cm. in diameter, 
rough with irregular scale-like leaf-bases: leaves tufted, flat, 
orbicular; petioles 52 cm. long, 15 mm. thick at base, 10 to 12 
mm. at apex, not including the spines, 5 mm. thick at base, 3 
mm. at apex ; upper face moderately concave, subcarinate in the 
middle distad; lower face strongly convex in the middle, con- 
cave on each side; upper surface with fine longitudinal or 
oblique impressions, doubtless from the next leaf; lower sur- 
face nearly smooth, very finely grooved longitudinally ; both 
surfaces covered with a thin layer of waxy scales; toward the 
margins are small scattering brownish longitudinal scars, more 
numerous on the upper side; occasionally there arises from such 
а scar a narrow scarious ribbon 2 mm. or less in length; these 
evidently correspond to the peltate scales of the leaf-bases and 
petioles of /nodes; margins of petioles thickened, smooth, 
corneous, in color pinkish-brown (vinaceous-cinnamon, Ridgway) 
at base, and dark brown distad; teeth somewhat irregularly 
placed, usually about 1 cm. apart, but sometimes 2 cm. and some-
