VOL. IV.] Some New and Some Old Algce. 359 



of Carmel Bay where Mr. Winston and his parents have col 

 lected many novelties, and some of the most beautiful Algae 

 ever found on our Coast. 



Prof. Farlow, who has examined specimens of this alga, is 

 inclined to the opinion that it is the same as Coilodesma Califor- 

 nica of Ruprecht and Kjellman. Coilodes?na is the old genus 

 Adenocystis of Hooker and Harvey, Flora Antarctica. This 

 may be so. But our plant seems to agree so well with the Dic- 

 tyotaceae and the genus Punctaria that I am inclined, notwith- 

 standing differences in structure of frond and fruiting, to regard 

 it as belonging properly as above indicated until Coilodesma is 

 proven to stand in place of Punctaria. 



Desmarestia aculeata, Lmx. 



{Class, Melanophyce^; Order, Ectocarpace^.) 



This alga was collected at Moss Beach, near Pacific Grove, 

 by Bradley M. Davis, in June, 1892. The long cord-like 

 branches and even the main stems were covered with a fine growth 

 of branching filaments. It does not seem to be abundant, as this 

 "find " is the only one I know of. It is common on the Atlantic 

 Coasts and has also been collected at Kamtschatka, on the north- 

 west coast. 



Desmarestia viridis, Lmx. 



(Fucus VIRIDIS, F/.Dan.; Dichloria viridis, Grev.~) 



This is a long known European alga, and was found on 

 the Alaskan Coast, but was not discovered on the Californian 

 Coasts so far as I know, until the summer of 1892, when Mrs. 

 B. C. Winston collected it in Carmel Bay, adding this pretty 

 alga to many other unexpected trophies found in the line of 

 natural history on that beautiful bay. 



Nemalion lubricum, Duby. 



{Class, Rhodophyce^; Order, Helminthocladiace^.) 



This long known alga, found in the Mediterranean and Adri- 

 atic Seas and on some Atlantic Coasts, has recently been dis- 

 covered in Monterey and Carmel Bays. "Worms" is the 

 common name in these localities, and very appropriately, for the
