Halicornaria bryani Nntting, new species. 
(PL vi, fig. 4; pi. xm, figs. 13, 14.) 
Trophosorne:— -Colony parasitic on Lytocarpus similis, attaining a height of about 3 inches. Stem 
simple, divided into regular internodes, each of which bears, a hydrocladium. Hydrocladia stout, not 
evidently divided into internodes. Hydrothecse very large, ovate in outline, margin with 1 or 2 ill- 
defined lateral sinuations; intrathecal ridge anterior, very strong, ending in a round knob. Supra- 
calycine nematophore small, not reaching to margin of the hydrotheca; mesial nematophore very 
short and strong, variable in shape, with a regularly arched outline and ending considerably below the 
hydrothecal margin. 
Gonosome. — Gonangia obconoid, with truncate summits, borne in a row on the front of the stem, 
each being at the base of a hydrocladium. No phylactogonia. The hydrothecse of this species are the 
largest that I have seen in the genus. 
Locality. — Station 4000, southwest of the island of Kauai, 213 fathoms.
