Howe: Nores oN BAHAMAN ALGAE 97 
specimens of Harvey’s collecting at Key West now in the her- 
barium of Columbia University, in which the number of spores 
to a sporangium is 200 or more. The peripheral arrangement of 
the spores about a central cavity, which Cramer emphasizes as a 
distinctive character of his Botryophora Conquerantii, and which 
that variety has in common with our variety /axus, seems to be 
more constant than number and size of spores and may be more 
significant. | Specimens agreeing essentially with Cramer’s de- 
scription of Botryophora Conguerantii have been collected by the 
writer at Key West, Florida (xo. 1531). 
Neomeris Cokeri sp. nov. 
Plants subcylindrical or clavate, 7-14 mm. long, 1.5-2.5 mm. 
thick, dark green in upper third or fifth, becoming grayish white 
elow, apex rounded-obtuse or subtruncate, often exhibiting a 
delicate, translucent apiculum formed of the mantle-caps : * num- 
ber of successive whorls of branches mostly 60~120; number of 
branches in a whorl 12-56: hairs of two forms in separate zones, 
those of one form consisting of a single, clavate, often curved or 
Somewhat hooked cell rich in chlorophyl and having a maximum 
diameter about equal to that of the supporting cell, the apex acute, 
obtuse, or more often apiculate; those of the second form con- 
sisting of a somewhat similar though slightly narrower basal cell 
bearing at its apex one or two earlier caducous, more slender 
branches, these in turn each bearin 2-4 branches ; unicellular 
airs or basal cells of the multicellular persisting in the upper 
third or fifth of the plant, the surface after their fall appearing 
Somewhat shaggy or minutely and irregularly punctate, a cortex 
Scarcely developed: branches of the first order lightly calcified, 
Scarcely coherent ; branches of the second order more strongly 
calcified, irregularly and imperfectly coherent, subfusiform, often 
Somewhat curved or gibbous, broadest (100-150 2) a little above 
the middle, tapering to a conico-truncate apex 22-344 broad at 
the insertion of the hair: sporangia strongly calcified, free or co- 
herent in short rows of 2-8, pyriform-obovoid, 180-206 yt long 
(decalcified and including stalk), go-102 in maximum width, 
calcareous capsule 25~40 4 thick; spores obovoid, 140-156 ux 
82-94 . (PLATE 6, FIGURES 3-12. 
Opposite Current Town, Eleuthera, July 5, 1903. The 
Material collected consists of about thirty individuals.
