6 EUDENDRIUM ATTENUATUM. 
Eudendrium exiguum. 
IPE Eigse: ae 
Trophosome. — Wydrocaulus attaining a height of about an inch, irregularly 
branched, fascicled in main stem; principal branches and ultimate ramiuli 
slender, mostly annulated at their origin. Hydranths with about twenty 
tentacula. 
Gonosome not known. 
Dredged from a depth of 98 fathoms off the Florida Reef. 
This is a small species; it is strongly fascicled towards the proximal end 
of the main stem, but the branches are for the most part monosiphonic, very 
slender, and with very thin perisare. 
Eudendrium fruticosum.

Trophosome. — Uydrocaulus attaining a height of about two inches, much 
and irregularly branched; main stem and base of principal branches fasci- 
cled. Hydranths with about twenty tentacles. 
Gonosome.— Male gonophores bithalamic, springing in a verticil of about 
ten from the body of the hydranth. Female gonophores oval, also spring- 
ing in a verticil from the body of the hydranth. 
Dredged off Key West from a depth of 135 fathoms. 
This is a strong, confusedly branched form. The annulation of the peri- 
sare is either altogether obsolete or is at most represented by a few obscure 
rings at the origin of the ultimate branches, or an occasional group of rings 
near the middle of their length. The stem is thick and strongly fascicled 
below, where it resolves itself into numerous hydrorhizal filaments. 
In the hydranths which carried the gonophores there was no tendency to 
atrophy in the male, and but little in the female. 
The specimen was loaded with small spherical capsules,— probably a 
mollusecan or annelidan nidus,— which adhered to the stem and branches 
in dense clusters.
