Trofhosome} — Hydrocaulus springing from a creeping rootstock, unbranched. The 

 pedicels are rather long and slender, from two to four times the length of the hydrotheca, 

 annulated at the proximal and distal ends and often with one or two annulations in the middle. 

 The hydrothecse are small, considerably smaller than in allied species; tubular, being usually 

 about three times as long as wide and with the hydrothecal walls almost parallel for about 

 half their length; margin armed with from seven to ten long acuminate teeth; hydrothecal 

 walls distinctly fluted, the vertical flutings corresponding in number to the teeth and extending 

 do^vnward from the margm to the basal third of the hydrotheca. 



Gonosome. — Unknown. 

 ■ This seems to be a very well marked species, in spite of considerable variation in the hydro- 

 thecal teeth. The general form and style of ornamentation is quite constant, and these hydro- 

 thecaB bear a very close general resemblance to those of Ohelia hicuspidata Clark, but differ 

 in the teeth, which are distinctly bimucronate in the latter species, while they are sharply pointed 

 in O. Icincaidi. This species differs from O. hincksii in being very much smaller and in having 

 acuminate instead of square teeth, and from C. grcRnlavdica in shape and in the character of 

 the teeth. 



I take pleasure in naming this species in honor of Prof. Trevor Kincaid, who has done 

 much to develop our knowledge of the marine fauna of the Puget Sound region. 



Distribution. — Puget Sound (Nutting) ; Dodd's Narrows, Vancouver Island (Fraser)

TropTiosome.^ — Colony consisting of unbranched pedicels springmg from a creeping root- 

 stock. Rootstock gro^vulg over specimens of Campanularia universitatis Torrey, very slender 

 and delicate, without regular annulations and rising into a thickened hump just below the 

 base of each pedicel. Pedicels distant, not branched. Pedicel and hydrotheca attaining a 

 height of 1.5 mm.; pedicel varying greatly in length, usually with a group of annidations at 

 each end with the intervening portion smooth. Occasionally, however, the pedicel is annulated 

 throughout. Hydrothecas long, campanulate, sometimes almost tubular; margin with 8
