358 Some New and Some Old Alge. [ZOE 
and still more narrowed, with a transverse dorsal crease on 
anterlor two-thirds, making it appear as two segments. In con- 
tracted alcoholic specimens the seventh and eighth segments are 
the widest; but in a fresher specimen the mesothoracic to eighth 
segments are about same width, 9 and 10 hardly narrower. 
Anal prolegs more developed than others. 
Described from six alcoholic specimens, five, including the 
largest, collected March 15, 1891. Color noted in life. 
SOME NEW AND SOME OLD ALG BUT RECENTLY 
RECOGNIZED ON THE CALIFORNIA COAST.

PUNCTARIA WINSTONII 0. sp. 
(Class MELANOPHYCE; Order DICTYOTACEZ. ) 
Fronds tufted; arising from a small naked disk, with very 
slender filamentous stipes, which gradually widen into tough, 
leathery, areolated lamina, thin, membranaceous, 4-1 inch wide 
and 2-10 inches high, of a dark olive green color. Cells cuboidal 
or roundish. Oogonia and fetraspores in the same sori, the 
former spherical or pear-shaped. Hairs and paraphyses absent. 
Adheres well to paper, and in drying has a distinct odor of new 
leather. In the older plants there are perforations, erosions, and 
lacerations of the leaf. 
For a long time I have wondered why species of Punctaria 
had not been discovered on our Coast. Last summer Mr. Harry 
B. Winston, a young and zealous collector of Algze, found this 
species at Carmel Bay, growing on the old stems of Egregia. It 
seems closely allied to P. plantaginea, Roth., of the Atlantic 
Coasts in shape and color. It has probably been mistaken 
when young by collectors for Phyllitis fascia, which it slightly 
resembles and which is very common. It differs from P- 
plantaginea in having spherical or pear-shaped oogonia in$tead 
of cuboidal, and in the absence of hairs and paraphyses. 
Probably it grows on the rocks and on other alge than Egregia, 
but so far has only been found on that one plant. It grows in 
a sheltered cove near Chinese fishing huts on the north side 
February 7, 1594.
