surfaces are both sharply convex, and there are convex lateral 

 surfaces as well ; in fig. 8 a transverse section of the lorica is given, 

 showing its four-lobed form. This may be easily obtained from 

 the live animal, as it has a habit of swimming head downwards with 

 its trochal disk close to the glass. 



Mr. Bolton found this pretty little rotifer last summer in the 

 same water with Conochilus dossuarius. 



Taphrocampa Saundersias n. sp. Gosse. PI. XII. fig. 9. 



Mr. Bolton sent me several specimens of a new Taphrocampa 

 in July 1884. It is somewhat like Mr. Gosse's T. annulosa, but 

 differs from it in having a square curved hood projecting downwards 

 over the head, and looking like a hook in profile ; also in having 

 two colourless spots hke eyes on the head ; as well as a stout short 

 truncate tail, just above the forked foot. 



I did not notice the slightest trace of ciliary action about 

 the head, neither has Mr. Gosse observed any, either in this 

 species or in T. annulosa ; and yet it is possible that both animals 

 possess ciliated auricles, for Mr. E. B. Brayley, the Hon. Secretary 

 of our Bristol Microscopical Society, has given me a rough sketch 

 of an animal which is probably T. anmdosa, and which on several 

 occasions he observed to put out little tufted auricles from the sides 

 of its head and swim with "a slight vermiform movement." 

 He thinks also that " a row of very short cilia extend right across 

 the forehead." 



_ Mr. Gosse has named this new animal T. Saundersise, after 

 Miss Saunders, of Cheltenham, who has sent both to Mr. Gosse 

 and myself several specimens of rare Eotifera. 



I have been compelled by lack of leisure to give very brief 

 notices of the above new species, and but few figures ; but they 

 wiU be dealt with in a more satisfactory manner in the Monograph 

 on the Eotifera by Mr. Gosse and myself, which is now being 

 prepared for publication.
