POLYCH/ETA OF PLYMOUTH. 629 



(i.e. N. vulgaris), ivMch loves a station higher up " (Cat. Brit. Mus. 1865, 

 pp. 200 and 201). Ill tlie soutli-west of England this account of the 

 habitat appUes not to S. Girardi, but to S. fuliginosa, which is the 

 common shore and estuarine form, occurring in very large numbers, 

 whereas isolated specimens of S. Girardi are only very occasionally 

 found. On the west coast of Ireland, Southern (Proceed. R. Irish 

 Acad. XXXI. 47, 1914, p. 96) found S. vulgaris of Mcintosh {=S. 

 Girardi of Mesnil) generally living in sand, rarely in Laminaria roots, 

 and it was never abundant. S. fuliginosa was common locally in 

 Blacksod Bay, but not widely distributed. Mesnil {loc. cit. p. 146) 

 thinks it probable that the S. vulgaris of Cunningham and Ramage, 

 which was abundant in the Firth of Forth, is S. fuliginosa, and 

 that S. fuliginosa is the common species at Heligoland.

 Mesnil)."
