From L. areolata it differs in the absence of the large 

 sinuous spout, and in the thinness of the mouth-margin.

I have received from Port Curtis and King's Island two 

 distinct varieties, which seem referable to this species. In 

 both the polyzoary is very much convoluted, thin, and exces- 

 sively brittle; the cells are oblong, arranged in linear series, 

 separated by raised margins, and are partially filled in by a 

 dense granular membrane, leaving an oval or eliptical opening, 

 the edges of which are thickened. In specimens from Port 

 Curtis the cells are nearly square, the margins thick and 

 strongly crenulate, and the edge of the opening minutely 

 denticulate. In those from King's Island the cells are very 

 much more elongated, the raised margins are nearly smooth, 

 and the membrane is not so strongly granular; ovicells deeply 

 immersed. The first form occasionally occurs decumbent in 

 a single layer on algae.

Besides the large spoon-shaped avicularia, in one speci- 

 men, there are numerous others, small, scattered, and with 

 pointed, triangular mandibles, mostly directed obliquely across 

 the cells.
