80 fi broad and in another from deep water (25 fathoms) the spores 

 were 175ft long and 80^ broad, and as the form of the spores 

 also seems to be rather variable (compare the accompanying figures

 Different forms of the sporangia (compare text). About 40: 1. 



a, b and c) I do not think it necessary to consider the above-named 

 form as a special variety. At the end of the spore turning towards the 

 axis of the plant I have also clearly seen the cover mentioned and 

 figured by S o 1 m s (1. c. p. 68, pi. 8 b, fig. 8), recalling the cover in 

 the spores of Acetabularia (cfr. my figure 2). 



In Phycotheca Boreali-Ameri- 

 cana (668) I some years ago without 

 examining the material very closely 

 wrongly gave specimens of this 

 species the name of N. dumetoaa; 

 Howe has already pointed this 

 out(Bull.Torr.Glub,Vol.31,pag.99). 

 Neomeris annulata occurs both 

 on sheltered coasts and on exposed. 

 In the first mentioned locality I 

 found it growing gregariously on 

 stones quite below the surface of 

 the sea in the full daylight and in 

 clear water without being covered by other algse. 



In the Bovoni lagoon it occurs together with Acetabularia 

 erenulata on stones near the shore in shallow water. On more
