 fath. {^Challenger ').

The Port-Phillip specimen differs from those found in 

 European waters in having the stalks shorter and thicker in 

 comparison with the heads of the polypides. The stalks are 

 covered with spines and much contracted at the point of junc- 

 tion with the poljpides. 



Hah. Creeping on Algae. 



Genus Ascopodaria, Busk. 

 Ascopodaria gracilis^ Sars. 



Hah. The jointed reticulate stolon creeps on Algae. Five 

 or six stolon-shoots radiate out from the base of each poljpide- 

 stalk and join with those from other polypides to form an 

 almost regular reticulum. The upper end of the chitinous 

 portion of the polypide-stalks is pointed on one side as in A, 

 fndicosa^ Hincks.
