The description Driven above is taken from a specimen from Station iT.Cs. and belongs to the 

 variety r<>l>itxf<i Allnian. which liardlv ditfers in anv essential character from the original British 

 form. The species, as indicated above, has a very wide distribution, but has not as yet been 

 found in the Pacific.

Trophosome. Colony attaining a height of 1 : i inches. Stem not fascicled. tle\itoM\ divided 

 into regular slender internodes, each of which boars a hydrotheca. Branches irregular and 

 sparse, themselves sometimes branching dichotomously, divided inio lonu. slender internodes, 



each beai'ine; a hydi'otheca. Hydrotheca' distant, rather slender, free for nearly their distal 

 two-thirds, proximal ends swollen, narrowing regularly to their distal end. which is much more 

 slender and narrow than in allied species, the upper side heiii- marked by shallow corrugations; 

 maryin witli four equal and equidistant teeth and a conical operciilum composed (P f four Haps.

It is impossible to tell from ('alkins's li"-ure and description whether the species that lie 

 idcntitied as .V. <-i>/i/'r<i is correctly determined or not. There is nothing to indicate the number 

 of hydrothecal teeth. The hydro! hecie seem to be very stout and closely approximated for that 

 species. I>r. Torrey ' identities a species as .S'. mnii-ii that cannot be placed in that species on 

 account of having three instead of four hydrotheeal teeth. It seems doubtful thai the species 

 has as yet been correctlv reported from the Pacific coast.
