attenuate and pendant. In place of the hydrorhiza the basal part of the pedicel is frayed out, :is it 

 were, into numerous hollow tubular processes. 



diiniixiiiii;'. Gonopbona borne on branched peduncles inserted aliove the |>roxiinal row of 

 tentacles'. Medusa 1 with 1 large tentacle and usually 3 much smaller ones. 



I'd/nr. Ilydrauth body mid gonophotOB bright pink. Medusa with light-yellow proboscis and 

 pink tentacle bulbs, 



Distribution. Sandy and muddy bottoms in rather deep water. The specimens in the 1*. S. Fish 

 Commission collection at Woods Hole tire not labeled, but are said to be from .Smith Hole. 



TUBULARID/E. 



Ti-n/ilna>iiiiii'. Hydrocaulus with a distinct tubular perisarc, branched irregularly or not at all. 

 Hydranths with a proximal and distal set of filiform tentacles. An adherent, creeping hydrorhiza 

 often produced, 



doiniKdiiii'. (ionophores borne above the proximal whorl of tentacles on branched peduncles, and 

 not producing free medus;e. The female*) produce hydra-like actinules which develop directly into 

 new colonies,

(Cimt. Nat. Hist. U.S., IV, p.2(!li.) 



Ti-11/ilniKftnn: Stems unbranched, often annulated, attaining a height of 5 to ~! inches. Hydranth 

 large, probably the largest on our coasts, often expanding an inch or more; proximal whorl of tentaclea 

 30 to 40 in number; distal set very much smaller and shorter. 



(iiiiiiiKiiiiii: (Jonophores growing in dense racemes from the hydranth body just alx>ve proximal 

 whorl of tentacles. Sessile medusje with 4 radial canals and without tentacular processes at the oral 

 end. Females producing actiuules. 



Culm: Stem and gonophores bright scarlet. 



Dutribution. Found in brackish water usually. A number of beautiful specimens were sent me 

 by Dr. Mead,' of Brown University, who hail them growing in a submerged flatboat at Providence, 

 R. I. A few specimens were taken from a depth of 30 fathoms by the Fixli Hairk in latitude 40 49' 

 45", longitude 70 42'. Mr. George Gray reports them from Quick Hole and off Nobska Point,

Trophoaome. Colony bushy; stems branched and extensively annulated, attaining a height of 1

 Hydranth with 16 to 20 proximal tentacles, and about the same nnmber in the distal set,
