124 Notes on AlgCB. [zOE 



and somewhat fleshy; surfaces of the frond, especially toward 

 the bases, delicately and closely marked with fine anastomosing 

 wrinkles; margins of the frond repand and somewhat loosely 

 dentate, or even closely serrulate. Tetrasporangia unknown. 

 Cystocarps situated in the medullary layer, prominent on both 

 surfaces, elongated oblong in shape. 



Known only from a series of specimens collected by N. L- 

 Gardner on the shores of Whidby Island, Washington, evidently 

 cast up from deep water, attached to the stipes of kelp and per- 

 haps other large Algae. 



This species has the frond of Dilsea Californica (J. Ag.) 

 Schmitz, but the cystocarp of Iridaea. It is to be distinguished 

 from the various forms of /, laminarioides Bory by the shape of 

 the cystocarp and the markings of the surfaces of the fronds. 



Callymenia reniformis (Turn.) J. Ag. This is a species of the 

 warmer European waters, which has appeared on both the Atlan- 

 tic and Pacific shores of North America. It was first detected 

 washed ashore on the beaches in the neighborhood of Monterey 

 and Pacific Beach, by Mrs. J. M. Weeks. The first specimens 

 sent to the writer by Mrs. Weeks, were received in September, 

 1896. Later the writer found it in more or less abundance in 

 the same localities. Both cystocarpic and tetrasporic plants are 

 found, some of them of fairly large size, It is absolutely differ- 

 ent in its appearance and texture from C. Californica Farlow, 

 which is often found washed ashore with it. It has been found 

 growing in water of from ten to fifteen fathoms deep, off Mon- 

 terey, by C. P. Nott. 



Fauchea laciniata J. Ag. This species, described by J. G. 

 Agardh (Till Algernes Syst., IV. p. 40) from Santa Barbara, 

 has been found by Mrs. J. M. Weeks and by the writer, cast 

 ashore in some abundance on the beaches near Monterey and 

 Pacific Grove. The tetraspores are in nemathecia or sori and 

 occur in abundance on both surfaces of the frond. The sori are 

 rather narrow and elongated, and are arranged in more or less 

 distinctly fiabellate lines, extending from near the base of the 

 plant to the ends of the lobes. Cystocarpic plants have also been 

 found by X. L. Gardner, on the shores of Whidby Island, Wash-
