The Rotifera of South Africa. By Charles F. Ronsselet. 401 



the town. The water in this tank was coloured green by a minute 

 alga, Microcystis ceroginosa, and in the sample I brought away I 

 afterwards found the following five species of Eotifers — 



Conochilus dossuarius Hudson. Abundant. 

 Brachionus pala var. dorcas Gosse. Abundant. 



„ angidaris var. caudatus Barrois and Daday. 



Anurcea aculeata var. valga Ehrbg. 



„ cochlearis (forma micracanth a) Gosse-Lauterborn. 



The B. pala var. dorcas found here is remarkable for very long 

 and very narrow anterior and posterior spines, as represented in 

 PI. XV. fig. 3, the European species having rarely posterior 

 spines. 



B. angularis var. caudatus is a variety not yet found in England, 

 but described by Barrois and Daday from Syria (2) ; the posterior 

 protuberances guarding the opening of the foot are here prolonged 

 into slightly diverging spines of considerable length. 



One day of our stay at Bulawayo was devoted to an excursion 

 to the " World's View," a rounded granite mountain in the Matoppo 

 Hills, where Cecil Bhodes's grave is situated, and commanding a 

 grand view of a magnificent series of hills formed of huge and 

 fantastic granite blocks and masses of rock. A branch line of the 

 Bhodesian Railway brought us within six miles of the " World's 

 View," and close to the railway terminus a large and comfortable 

 hotel has been built, a kind of sanatorium where a very enjoyable 

 holiday could be spent. The country here is no longer so dry, and 

 streamlets with running water could be seen in various directions, 

 also farms and herds of cattle. From the hotel to the foot of the 

 " World's View " we were driven by brakes, stage-coaches, hunting- 

 cars, twenty-one in number, of various degrees of antiquity, drawn 

 by eight and ten mules each, over a sandy and bumpy road, through 

 a grassy plain first, then through a narrow valley flanked by granite 

 rocks and ridges. A novel experience here was the encounter with 

 a large swarm of red locusts, which rose in millions like a cloud. 

 At the spot where the carriages were out-spanned a streamlet with 

 a fair amount of clear water formed pools here and there, and a bog 

 at one place, where I saw a number of the Sundew, Drosscra, grow- 

 ing and in flower. I tried various of these pools, but could see 

 nothing more than a few Infusorians, in particular a bright red 

 Stentor, in the water, and so took no sample. My subsequent 

 experience has taught me that it is better to condense and preserve 

 a sample of any such water, as Rotifers are sure to be found in the 

 sediment when carefully examined later on at home. On our 

 return journey I stopped the carriage when it was crossing a 

 streamlet which formed a pool by the wayside, jumped off, passed 

 my net quickly through the water a number of times, and jumped 

 on again — all done in less than two minutes. When I examined
