Variations. — All our specimens were dead, reduced to small frag- 

 ments and deprived of all chitinous appendages. Nevertheless the 

 specific characters are quite visible; the dorsal granulations, longi- 

 tudinal vibices, large avicularia, variations of the peristome and 

 traces of two large antenniform spines. However, the fenestrules are 

 frequently larger than the trabeculae. 



Biology. — This is a shallow water species which is abundant around 

 Australia.

Description. — The zoarium encrusts shells. The zooecia are little 

 distinct, somewhat elongated, elliptical; the frontal is a little convex, 

 covered with large granules and ornamented with a lateral, triangular 

 avicularium with pivot, in which the beak touches almost always the 

 proximal border of the apertura. The apertura is "suborbicular with
