'"Ti'ojilioHomi 1 . Stein monosiphonie, iniirh branched. Hydrothecse distant, adnate )>y about 

 half their height to the stein, from which they then become strongly divergent, epieauline side 

 ventrieose toward the base; orifice with a thickened rim and with a deep sinus at its upoeauline 

 side. 



' Jronoxa/iK -. Gonangia springing from the angles of the ramification, ovoid, marked by wide 

 transverse ruga' toward the summit and base.

I have not .seen this species, and have copied the above description entire from that of the 

 original describe! 1 . The figure would seem to indicate that there were three hydrothccal teeth, 

 although their number is not given in the description. The form bears considerable resemblance 

 to that of S. dic/iofo'ii", which came from the, same region and is apparently a very variable 

 species, so far as the trophosome is concerned. The gonangia, however, are quite different.

7'rt>j>/iiiNii/iii . Colony small, sometimes consisting of an unbranched stem, attaining a height 

 of about 1 inch in specimens examined. Stem genieiilate. divided into regular short inlernodes, 

 each of which bears a hydrotheca. Branches, when present, not regularly arranged, few in 

 number, and resembling the main stem in all respects. Hydrothecse closely approximated, rather 

 large, stout, subcylindrical, the ends being slightly constricted; aperture large, margin with 

 three unequally developed teeth, the two outer ones being very strong and equal, the other 

 smaller. As a rule less than the distal half of the hydrotheca is free. 



1,'iiiiiimiini.: Gonangia borne in the axils of the hydrotheca'. large, obovate, terminating in 

 a small inconspicuous aperture at the summit of a short collar, and with the distal portions 

 armed with a number of blunt spines, these being much metre numerous in some specimens than 

 in others. There is also a sort of dimorphism in si/.e which probably corresponds to M>\. the 

 larger gonangia being female.

I agi-ee with Ilartlaub in the opinion that the .V. n,nlnl,i>i <-!' Calkins is really identical with 

 the present species. The specimen from .Japan is more branched and the hydrothecse more 

 distant and more exserted than in other specimens that I have examined.
