row arrangement. The appearance of each tooth then becomes some- 

 thing like a carpenter's small chisel with a blade and a short 

 narrow shank. The blade stands about half its length above the 

 socket, and close to the jaw-bone as it were, stands out clearly the 

 short narrow shank. 



The division of the blade part of the tooth, standing half in and 

 half out of the socket apparently, causes the appearance of there 

 being two rows of teeth : at least, that is my impression. 



Loricata. 



Rattulus rattus Ehrenberg. — What I concluded was this, I found 

 in December 1903, on the coast near home, clinging to the stems 

 of our blue water-lilies. 



Diaschiza gibbet Ehrenberg. — A few specimens that seemed to 

 comply with Hudson and Gosse's description and illustration of 

 Furcularia gibba, now transferred to the genus Diaschiza, were found 

 in a slow moving pool of the Umzinto in November 1904. I have 

 not come across it again since. According to Dixon-Nuttall, 

 Gosse's D. semicqjerta belongs to the same species. 



Metopidia oxystcrnum Gosse. — For a short time this was seen 

 in great numbers in pools near home, September 1901. 



Brachionus angularis Gosse. — In a small pool on the rocks 

 with the water discoloured by unicellular algre. This was found 

 by Mr. Tyrrell and myself, September 1902. 



Anurcea aculcata var. curvicornis Ehrenberg. — I found this near 

 Maritzburg in 1902 and again on the coast in 1904. One specimen 

 was sent in a slide along with some A. valga and identified by 

 Mr. Eousselet. 



Anurcea aculeata var. valga Gosse. — I sent one or two specimens 

 of this, which was found by Mr. Tyrrell and myself in October in 

 one of the pools of the Umzinto, to Mr. Eousselet for identification 

 in December 1904. He said it was A. valga. We found that 

 there were seven teeth in each uncus — not five, as mentioned in 

 Hudson and Gosse. 



Anurcea cochlearis Gosse. — This was seen in small pools in the 

 Equeefa river in 1901 during November. 



Note. 



Pterodina trilobata Shephard. — In the Journal of the E.M.S. 

 1901, on page 241, Mr. Eousselet refers to the mounted specimen 

 I had sent to the Society in these words : — " Lateral canals and 

 vibratile tags could not be found in the mounted specimen, but 

 near the base of the stomach on each side I observed a cluster of
