Trofhosome} — Colony consisting of a creeping rootstock from whicli unbranched pedicels 

 arise. The rootstock is smooth and slender. Pedicels long, in one case attaining a length of 8 mm. ; 

 smooth, for the most part, but showing on the distal end a series of what appear to be short 

 nodes, the upper part of each node being broadened. Below each hydrotheca is a small but dis- 

 tmct disk-shaped annulation. The hydrothecse are large tubular, the sides being parallel for the 

 greater part of their length and the lower portion forming a semicircular outhne ; margin with 

 14 deeply-cut teeth, each of which is flattened on top and has a considerable portion of its opposite 

 sides parallel. The hydranth cannot be studied in the specimen described, but Hartlaub says 

 that it bears about 27 tentacles. 



Gonosome. — Gonangia borne on the rootstock, oblong-oval in form, about 3 mm. long 

 and four times as long as broad, the upper end being squarely cut off and the lower end passing 

 insensibly into the short smooth peduncle. The gonangial waUs are smooth and their contents 

 are indeterminable in specimen studied, although in one case there is what appears to be a 

 sporosac. 



Distribution. — The type-locahty is Calbuco, Chile. 



The present writer doubts very seriously the identity of this species with the one described 

 under the same name by Hickson and Gravely.^ Neither the hydrothecae nor gonangia repre- 

 sented in the figures (pi. 4, fig. 26) are sufficiently hke C. Ixvis to be placed in that species. 



? CAMPANULARIA BREVICAULIS, new species. 



Plate 6, figs. 1, 2. 



Trophosome.^ — The fragmentary colony is growing over Sertularella cylindritJieca and 

 consists of a slender creeping rootstock which appears to be without annulations. The pedicels 

 are in every case considerably shorter than the hydrothecse and usually not more than haK as 

 long, smooth, with the exception of one or two annulations just below the hydrotheca. There 

 are no annulations nor constrictions where the pedicel joins the rootstock. The hydrothecse 

 are of moderate size, deeply campanulate, almost tubular, in form, with the proximal end nar- 

 rowing gradually to meet the pedicel, and the margin is ornamented with usually eight broad 

 truncated teeth in the ends of which show a concave profile, giving a turreted appearance. 

 The diaphragm is well marked and the basal chamber subspherical in shape. 



Gonosome. — ^Unknown. 



Although but a mere fragment of this form was secured it differs so materially from any 

 other known to the writer that it seems best to give it a specific name. The combination of 

 turreted teeth with very short pedicels does not occur elsewhere among the unbranched species 

 of Campanularia. 



Distrihution. — The type-locahty given above, which is between Havana and Yucatan, 

 depth 194 fathoms, is the only locahty from which the species is known. 



Type.—Cnt. No. 34527, U.S.N.M.
