StreUonema fasciculatum Saunders, Phyc. j\Iem., 1898, p. 148 (not 

 of Thuret). 



Examination of a small piece of authentic material of S. fascicu- 

 latum Saunders collected at San Pedro, California, in August, 1896, 

 revealed the presence of specimens of the same three species mentioned 

 under S. corymhif erum of this paper, collected by ]\Irs. Johnston at 

 the same place and in the same month. S. anomalum is undoubtedly 

 the one to which Saunders refers as *S'. fasciculatum Thuret. It does 

 not seem, however, to be this species, if we have a correct conception 

 of what S. fasciculatum Thuret includes. This species was published 

 in Le Jolis, Algues marines de Cherbourg, no. 100, and in Liste, 1863, 

 p. 73. Thuret quotes as a synonym, S. voluhilis Pringsheim (Beitr. 

 Morph. Meeres Alg., p. 13, plate 3, fig. B, read in 1862) . Pringsheim 's 

 figure of voluhilis shows the gametangia fasciculately branched, and he 

 states that this charatcer is one of the chief characters of the genus 

 Strehldnema. This figure has been much quoted since. He gives no 

 measurements of the parts, neither does Thuret. 



Reinke (Algenfl., 1889. p. 41) recognizes Strehlonema as a sub- 

 genus of Ectocarpus. He recognizes Pringsheim 's plant, quoting the 

 above figure, but since voluhilis was already occupied by Crouan (1867, 

 p. 161) and fasciculatum was occupied by Harvey (Phyc. Brit., pi. 

 273), he renamed the plant, calling it Pringsheimii. Hauck (1884, 

 p. 323) seems to have been the first to give measurements of the 

 various parts of the plant. He lists it under Strehlonema, cites the 

 above literature of Thuret, and quotes S. voluhilis Pringsheim. Con- 

 sidering Pringsheim 's plant, recognized by Reinke and Hauck, as 

 being the same as Thuret 's, and taking Pringsheim 's figure and 

 Hauck 's measurements as being correct for Thuret 's S. fasciculatum, 

 then our plant is distinct and undescribed. 



There is a little doubt at present in our minds whether the plant 

 we are here describing as Strehlonema anomalum. is one or two species. 

 We do not find the filaments bearing the zoosporangia in the type
