counectiou with the rectum, in which the pumping movements 

 are so clearly seen. There was one very large coloured egg, 

 situated definitely to the right and rather to the posterior of 

 the body. 



The movements of this Eotifer were always brisk. The 

 whirlpool made by its cilia was noticeably large, strong, and 

 far-reaching. The head was retracted completely, though 

 only occasionally, and then the anterior spines of the lorica 

 were seen to perfection. 



I found also another Brachionidsean of very much smaller 

 size, but rather similar appearance. It had no egg. I did 

 not get a complete drawing or description of it, and so have 

 just mentioned it. 



Both these Brachionidseans came from a ditch which was 

 in communication with the tidal x\katore Creek. The water 

 was sufficiently saline to taste so, and for the salt to crystal- 

 lize on the slide.
