 manner, and have the same beautiful honeycomb appearance. 



Habitat. — Tree and rock moss, Grahamstown and Umtata. 

 Fairly numerous. 



A good many other species of Bdelloida were examined suffi- 

 ciently to see that they were different from any that have been 

 hitherto described, but owing to some detail or other being 

 absent from my notes I have not attempted to describe them. 

 There was one dainty, pert little Macro trachela, with a very 

 distinctive antenna equal in length to three times the neck 

 width, motile, and with a rhythmic beat in unison with the 

 motion of the jaws ; found on weeds in running water. 



I intended giving a list of all the Bdelloida I observed in South 

 Africa, but find it impossible to do so at present. This list may 

 appear as an Appendix to the above on some future occasion.
