Trophosome . — Colony much branched , attaining a height of 4 or 5 inches ; stem fascicled ; annulations 

 at the base of the branches and pedicels. 



Fig. 6. — Eudendrium capillare Alder. A, cluster of female gonophores growin^t rom the hydrorhiza; B, cluster of female gono- 

 phores growing from the stem; C, cluster of male gonophores growing from the hydrorhiza (after Allman); D. cluster of 

 male gonophores growing from the stem (after Allman). 



Gonosome. — Female gonophores borne on aborted hydranths, commonly with a zigzag arrangement 

 from the end of the pedicel , this pedicel being more or less annulated throughout ; often a scries of pedicels 

 appear in succession from a single branch. 

 They may be close enough together so that the 

 series of gonophore clusters may look like a 

 single cluster. Over a large portion of the sur- 

 face of each gonophore the perisarc is ver)'much 

 thickened. Male gonophores are clustered 

 about an aborted hydranth. The cluster is 

 much larger than in any other species found in 

 this locality, five chambers being common. 

 The reproductive hydranth is attached to the 

 pedicel of an ordinar>' hydranth a short dis- 

 tance from where the latter is attached to tlie 

 branch. 



Color. — Hydranths and gonophores red. 



Distribution. — (Common on piles of United 

 States Bureau of Fisheries wharf and on piles 

 of the Norfolk Southern Railroad bridge from 

 Morehead City to Beaufort; dredged near 

 Shackleford, 12 feet.
