P.S. — Jan. 10, 1901.— Since writing the above I have made some- 

 attempts at preserving and mounting, and am sending four slides,, 

 containing in all nine specimens of the large Pterodina, two slides 

 containing five specimens of the "puzzle" mentioned above, and 

 two slides containing five specimens of what I take to be Scaridium 

 eudactylotum. 



Rhizota. 



Floscularia cornuta Dobie. — This appears to be the only species 

 of floscule 1 have seen here during the summer months, and only 

 two or three times. 



Melicerta ringens Schrank. — I have found this both in the rocky 

 pools of the Equeefa, and also in various habitats near Maritzburg. 

 I have not seen any very large ones, or clustered ones, and no other 

 species of Melicerta yet. 



Limnias Ceratophylli Schrank. — This seems rare, as I have 

 only seen it in one habitat in 1899, growing on the tubes of the 

 fresh- water Polyzoon Fredericella sultana, in the rocky pools of the 

 Equeefa. 



Limnias annulatus Bailey. — I have found this in considerable 

 numbers at times, growing on bits of dead wood, stems of water- 

 grasses, &c, both here and about Maritzburg. 



Cephalosiphon limnias Ehrbg. — This was found in 1898, growing 

 along with L. annulatus, on bits of dead wood, in the rocky pools of 

 the Equeefa ; I have not seen it since. 



QLcistes. — One species only have I seen, consisting of only two or 

 three specimens growing on the stems of water-grasses in pools in 

 the Umzinto early this year, 1900. The specimens were very small, 

 and I could not. identify them. 



Bdelloida. 



Pliilodina. — There is one very common both here and about 

 Maritzburg ; it seems to be P. erythrophthalma Ehrbg., but I do 

 not feel certain. P. roseola Ehrbg. I think I have seen in hollows 

 in rocks where rain water has collected. 



There is also another species of Pliilodina here, always found 

 seated on threads of alga?, and having much the appearance of P. 

 megalotrocha Ehrbg., as figured by Hudson and Grosse, but certain y 

 the antenna is not unisetate. 



Rotifer vulgaris Schrank. — This is more or less common. 



Rotifer macrurus Schrank. — [ believe I have seen this, but it 

 does not seem common. 



Actinurus neptunius Ehrbg. — I have found this in considerable 

 numbers, attached generally to pieces of dead wood, lying at the 

 bottom of two or three very dark small pools in the rocky bed of the 

 Equeefa, hut not anywhere else. They seem to dislike the light very
