 On Algae between tide marks. Not common. Whitley, 

 Marsden, Roker, &c. — G. S. B. It is not uncommon to find 

 specimens of Jania which might, without much violence, be 

 referred either to J. ruhens or J. corniculata\ the same plant 

 often showing some filaments which one would call by the former 

 name, and some which appear by the greatly produced upper 

 angles of their articulations to belong rightly to the latter spe- 

 cies. Under these circumstances it would seem that one specific 

 name might rightly include both forms. — N. D.
