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

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

 also seems to be rather variable (compare the accompanying figures 



Fig. 1. Neomeris annulata Dickie. 

 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 Solms (1. c. p. 68, pl. 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. dumetosa; 



Howe has already pointed this 



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



Neomeris annulata occurs both 



on sheltered coasts and on exposed. 



In the first mentioned locality I 



Fig. 1 Neomeris annulata Dickie, found it growing gregariously on 

 ^pi.^o^^^m^m^A). stones qujte below the gurface of 



the sea in the full daylight and in 

 clear water without being covered by other algæ. 



In the Bovoni lagoon it occurs together with Acetabularia 

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