94 Howe: Notes ON BAHAMAN ALGAE 
ondary pinnules are pinnately distichous and corymbose, the low- 
ermost being as long as the rachis or slightly longer; the “pedi- 
cel”? supporting the four, five, or more digitate primary branches 
or “fronds” is very short, measuring in Dr. Coker’s specimen 
only 0.5-1.0 cm. 
CAULERPA PASPALOIDES (Bory) Grev. 
Green Cay, in 4 fathoms. 
RuHIPOCEPHALUS PHOENIX (Ell. & Soland.) Kuetz. 
Mangrove Cay, Andros, June 26, 1903. Dr. Coker’s speci- 
mens accord very well with Ellis’s original figure * in regard to 
the outline of the capitulum, but the flabella are broader, more 
crowded, and more erect. Specimens collected by the writer at 
Key West, Florida (zo. 2672, distributed in Phyc. Bor.-Am. as 
no. 1030) are extremely varied as regards the form of the capi- 
tulum, only occasionally offering the oblong-ovoid outline figured 
by Ellis. The capitula of some of these Key West plants are coni- 
cal, some are broadest near the top, tapering down to the stalk 
below, and others are much elongated and of uniform width 
throughout (sometimes g-10o cm. x I-1I.5 cm.), but these eX- 
tremes are connected by clearly intermediate forms and we thin 
but one species is represented. 
Uporea conciutinata (Ell. & Soland.) Lamour. 
Collected by Dr. Coker at several points; at Green Cay in 4 
fathoms of water. Udotea Flabellum (Ell. & Soland.),+ which is 
much the more common in southern Florida and Porto Rico, 
does not appear to have been found by Dr. Coker. 
MicropIcTyon crassum J. Ag. Anal. Alg. Cont. 1: 107. 1894: 
Green Cay, in 4 fathoms. We are using provisionally for — 
these plants collected by Dr. Coker the specific name applied by 
J. Agardh to specimens from the Bahamas sent to him by Mrs. 
Curtiss, though it is not yet wholly clear how either are to be 
kept separate from Microdictyon umbilicatum (Velley) Zanard. J. 
Agardh in proposing MZ. crassum as a new species appears to have —
