Family EXTALOPHOPJD.E. 
Diagnosis. 
Cyclostomata Tubiilata in which the zoariimi is erect and 
dendroid ; the branches consist of solid bunches of zooecia, 
which open all round the stem. There are no dactylethrm, 
cancelli, mesopores, or appendages. The marsupial chambers 
may be gonoecia or gonocysts. 
Affinities. 
This family differs from the Idmoniidae by the fact that the 
zooecia open on all sides of the branches ; it differs from the 
Eleidm owing to the presence of avicularia and the lateral or 
subterminal position of the apertures in that family. The basal 
areas, by which the zoaiium is attached, are bcrenicoid or 
proboscinoid.
