358 Some New and Some Old Alger, [zoe 



and still more narrowed, with a transverse dorsal crease on 

 anterior 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^E BUT RECENTLY 

 RECOGNIZED ON THE CALIFORNIA COAST. 



BY C. I.. ANDERSON. 

 PUNCTARIA WiNSTONII n. Sp. 



(Class Melanophyce^; Order Dictyotace.^.) 

 Fronds tufted, arising from a small naked disk, with very 

 slender filamentous stipes, which gradually widen into tough, 

 leathery, areolated lamina, thin, membranaceous, ^-i inch wide 

 and 2-10 inches high, of a dark olive green color. Cells cuboidal 

 or roundish. Oogonia and tetraspores 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 Algae, 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 diflfers from P. 

 piatitaginea in having spherical or pear-shaped oogonia instead 

 of cuboidal, and in the absence of hairs and paraphyses. 

 Probably it grows on the rocks and on other algae 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
