 1. Tai^lirocamim nitida, sp. nov. 



Sp. cli. — Body plump, cylindrical ; brain clear ; a decurved 

 frontal hood ; eyes two, pale ; an inconspicuous tail ; foot and toes 

 small, somewhat ventrally placed. 



For many years the author was an almost daily student of the 

 Rotifera of the Rossendale district ; regular " fishing " excursions 

 were made to a limited number of ponds, and notes were taken 

 of the gatherings. So systematically and well was the district 

 worked that the finding of an unfamiliar Rotiferon was a very 

 exceptional occurrence. Circumstances have prevented my doing 

 any microscopical work for over six years ; and on resumption, a 

 few weeks ago, the remarkable thing is that a very considerable 

 number of the Rotifera captured are species that never occurred 

 to me in my former close study of the class. From this it would 

 appear that there may be a gradual though material change 

 taking place in the Micro-Fauna, and presumably in the Micro- 

 Flora of various waters, even where there is no appreciable 

 alteration in the conditions — a point which, so far as I am aware,- 

 has not previously received recognition, 



From a pond rich in Micro- Algae, and which has afi'orded me 

 many unusual forms of the Rotifera, I collected this new Taphro- 

 campa. In this species, which is plump and grubdike, there are 

 not so many rings as in the three other recorded species. I could 

 never make out more than five or six, and what I may term the^ 

 internodes were convex rather than concave ; indeed, the annula- 

 tion in this form is not nearly so prominent a character as in the^
