Coelothrix irregularis (Harvey) Bprgesen 1915-

D. 13782. The tetrasporic material agrees 
exactly with Harvey. It is probably identical 
also with C. indica Bprgesen from Mauritius 
which seems doubtfully distinct in view of 
this Pacific record. The species is probably 
widespread in tropical waters but of infre- 
quent occurrence in the Pacific and Indian 
Ocean regions.

lection of Hypnea under no. 46-378 called 
H. spinella (A g.) Kiitz. is probably the same 
as these.
