layers of great extent over house-posts and fishino-poles. I fioure a 

 young colony just starting to spread over a bamboo. In this condition 

 the zooecia are regular in shape and uniform in size, but as the colonv 

 becomes congested many of them are distorted or dwarfed. This is the 

 case to a still greater extent on the shells of Gastropod molluscs 

 {Hydrohioides nassa, H. physcus, Taia intha, T. elitomlis and T. shanensis), 

 a considerable proportion of which are completely covered by its growth' 

 The four spines at the corner of the aperture are usually well developed 

 and the aperture more or less quadrate. In this respect the colonies 

 from the Inle Lake are more like those of the specimens figured by Carter 

 in his original description than any I have seen elsewhere. 



The species has probably a wide range in northern India and Burma.

A single colony of this species, easily recognized by its fan-shaped 

 buds, was found on the stem of a reed in the intermediate zone of the 

 lake near Fort Stedman. I have recently found it growing in abundance 

 on the lower surface of bricks and tiles at the edge of the river Hughli 

 near Calcutta. It was originally described from a small lake at Jalor 

 in the Siamese Malav States.
