8 BIMERIA HUMILIS. 
Eudendrium tenellum. 
PIIV. Figs. 3, 4. 
Trophosome. — Hydrocaulus attaining a height of about half an inch, very 
slender, not fascicled, irregularly branched; branches annulated at their 
origin; main stem and branches with groups of two or three annuli at 
distant and irregular intervals. 
Gonosome not known. 
Dredged off Double-Headed Shot Key from a depth of 471 fathoms. 
Eudendrium tenelum is « minute and very slender form, perhaps the most 
slender species as yet referred to the genus Eudendrium. Its reference to 
this genus is probably correct, but as neither hydranths nor gonophores 
were present in the specimen, it may possibly have its true place in some 
other. 
The specimens were obtained along with Sertularella amphorifera from the 
deepest dredgings made. 
Eudendrium cochleatum. 
BLV: Miigsole 2: 
Trophosome. — Hydrocaulus attaining a height of between two and three 
inches, not fascicled, alternately branched; main branches and ultimate 
ramuli with very distinct oblique annulation at their origin, and here and 
there with groups of three or four ordinary transverse annuli. 
Gonosome not known. 
Dredged off Cape Fear River from a depth of 6 fathoms. 
The strongly marked screw-like annulation at the origin of the branches 
forms a characteristic feature of this species. Some of the hydranths were 
well preserved in the specimen, but no gonophores were present. 
Attached to it were numerous specimens of a little tube-dwelling crus- 
tacean.
