throughout, as are also the branches and pedicels. Branches leave 

 the stem at an acute angle and pass upward in the same general 

 direction as the stem; pedicels for the hydranths forming an acute 

 angle with the branches. 



Gonosome. — Male gonophores borne on pedicels arising from the 

 main stem or the branches in a whorl, around the base of an aborted 

 hydranth; 3-chambered. Female gonosome not observed. 



Type.—V.S.'^M. No. 43433. Taken by the United States Fisheries 

 steamer Albatross southeast of Newfoundland, latitude 46°53' N., 

 ^ longitude 44°39'30" W., 76 fathoms, August 11, 1886. 



Genus CAMPANULARIA Lamarck 



7 CAMPANULARIA ABYSSA, new species 



Plate 32, Figure 2 



TropTiosome. — Colony 2 cm. high; stem simple, slender, not exten- 

 sively branched, usually one branch from a node, but sometimes 

 two opposite branches, making a wide angle with the stem; hydro- 

 thecae regularly alternate, with pedicels much the same length as 

 the hydrothecae; pedicel tapering into base of hydrotheca, and the 

 hydrotheca increasing in diameter very gradually to the margin, so 

 that the hydrotheca is not far from being tubular; margin entire, 

 sometimes duplicated; diaphragm delicate, much like that in Licto- 

 rella. 



The whole colony is almost free of annulations; occasionally there 

 is one near the proximal end of the branch and one or two through- 

 out its length, always appearing singly. 



Gonosome. — Unknown. 



Type.— U.S.N.M. No. 43434. Taken by the United States Fish- 

 eries steamer Albatross southeast of Cape Cod, latitude 39°22'50" 

 N., longitude 68°25' W., 1,608 fathoms, July 19, 1883. 



This species can be put in this genus only provisionally, since no 

 gonosome was present in the material. It is doubtful even whether 

 it should be placed in the Campanularidae, since the diaphragm is 

 not typically campanularian. 



Genus GONOTHYRAEA Allman 



GONOTHYRAEA INTEGRA, new species 



Plate 32, Figure 3 



Trophosome. — Colonies minute, less than 8 mm. in length, un- 

 branched, with one branch, or with very few branches; stem slender, 

 slightly geniculate, annulated at the base and above each node; 

 hydrothecae regularly alternate from pedicels that are annulated 

 at both ends, leaving only a small part free of annulations; hydro- 

 thecae broadly campanulate, almost or quite as deep as wide; mar- 

 gin entire.
