TUBELLA. 



I. T. Pennsylvanica, Potts. Monograph, p. 251. 



Specimens from Delhi, O., Philadelphia, and other localities

 One large rust colored piece was taken from a water main, 

 Philadelphia. It is interesting on account of its strange habitat.

1. C. tubisperma. Mills. Monograph, p. 263. 



Nmnerous typical examples from the Niagara and from dis- 

 tant localities. Very abundant at Buffalo growing on rocks 

 or .piers, often on the bottom of shallow bays. This was the 

 first species of sponge found at Buffalo. The writer's note 

 book contains a drawing of a statoblast made the day of the 

 "find" and dated October 11, 1S79. 



2. C. latitenta, Potts. Monograph, p. 264. 



Excellent specimens from Scajaquada Creek 1886. There is 

 much variation in the distal expansion of the tube and in the 

 fibres arising from the same.

Small example from Scajaquady Creek. 



It thus appears that all the species of the genus thus far 

 found in America occur at Buffalo.
