Fromtheir extreme fragility, the specimens, which are all dry, are allimperfect ; the longest piece is 40 millim. high ; but probably noneof the specimens exceeded 60 millim. in height and greatest widthrespectively. Perhaps half a dozen original specimens are represented.It is remarkable that the length of the internodes and the sizeof the large cortical spicule vary inversely to the stoutness of theinternodes.TUBIPORID^.38.

Klunzinger identifies a species from near Timor as T. rubeola,Quoy and Gaimard, and it does not appear that he met with thisspecies on the coast of Australia. T. rubeola, however, resemblesT. hemjyrichi considerably in the rather widely separated tubes andthe length of tube between the horizontal (external) diaphragms ; butin the latter point it exceeds T. hemprichi, and must be regarded asquite distinct from it, owing to the red colour assigned to its polypes,those of T. hemprichi being grey.
