Family IX. Eudendriidse. 



Poli/piics borne on a well-developed stem, with a single ver- 

 ticil of filiform tentacula surrounding the base of u 

 large trumpet-shaped proboscis.

GENERIC CHARACTER. Stem branched, rooted by a 

 creeping filiform stolon, the whole invested by a chitinous 

 polypary ; polypites borne at the extremity of the branches, 

 vase-shaped or roundish, with a prominent, trumpet-shaped 

 proboscis and a single verticil of filiform tentacula round 

 tlit base of it. Gonophores developed from the body of the 

 polypite below the tentacles, or from the stem, containing 

 fixed sporosacs the female simple, the male consisting of 

 several chambers arranged in moniliform series. 



THE Eudendria form a well-marked group. They are 

 most of them of decidedly arborescent habit, and bear 

 graceful and often brilliantly coloured polypites, which are 

 remarkable for their conspicuous funnel-shaped 

 proboscis. 



The gonophores are generally developed on the 

 body of the polypite, but sometimes occur on the 

 stem. In many cases the fertile polypite is atro- 

 phied and disappears, and the reproductive buds 

 hang in umbelliform clusters at the extremity of 

 the branches. 



The male sporosac is ultimately polythalamic, 

 consisting of several chambers placed one above another 

 (woodcut, fig. G). In its first stage it consists of a simple 

 spherical sac, borne on a peduncle, and enclosing a maim-
