 As the local rotatorian fauna has not been recorded previously, a list 

 of 246 species is given. A new genus, Rousseletia, and ten new species 

 are described: Rousseletia corniculata, Encentrum aper, E. myriophylli, 

 E. ricciae, Lecane stichaea, Monostyla acus, M. crenata, M. sylvatica, 

 Trichotria brevidactyla and Asplanchnopus hyalinus. A redescription 

 of Sphyrias lofuana (Rousselet) and some notes on Notonimata pachyura 

 (Gosse) , Diglena clastopis Gosse, Diurella pr ocellus (Gosse) and Testudi- 

 nella parva (Ternetz) are added. H. K. H.

 In this paper an attempt has been made to bring rotatorian nomen- 

 clature into agreement with the International Code of Zoological No- 

 menclature. As generally happens in similar cases, a number of generic 

 names become displaced by others. Thus Cephalosiphon, in the usually 

 accepted sense, has been replaced by Beauchampia, n. gen.; Anapus 

 Bergendal by Chromogaster Lauterborn; Diglena Ehrenberg partly by 

 Cephalodella Bory de St. Vincent, partly by Dicranophorus Nitzsch; 

 Floscularia Ehrenberg-Oken by Collotheca, n. gen. (Floscularia Cuvier 

 displacing Melicerta Schrank.). Encentrum Ehrenberg is substituted 

 for a group of species previously distributed among several genera; 

 Enter oplea Ehrenberg for Triphylus Hudson; Epiphanes Ehrenberg for 

 Hydatina Ehrenberg and Notops Hudson; Filinia Bory de St. Vincent 

 for Triarthra Ehrenberg; Keratella Bory de St. Vincent for Anuraea 

 Ehrenberg; Lecane Nitzsch for Cathy pda Gosse and Distyla Eckstein; 

 Lepadella Bory de St. Vincent for Metopidia Ehrenberg; Macrochaetus 

 Perty for Polychaetus Perty; Macrotrachela Milne for Callidina Ehren- 

 berg; Pedalia Barrois for Pedalion Hudson; Philodinavus, n. n., for 

 Microdina Murray; Ptygura Ehrenberg for Oecistes Ehrenberg; Rhino- 

 glena Ehrenberg for Rhinops Hudson; Rotaria Scopoli for Rotifer Cuvier- 

 Schrank; Sinantherina Bory de St. Vincent for Megalotrocha Ehrenberg- 

 Bory de St. Vincent; Squatinella Bory de St. Vincent for Stephanops 

 Ehrenberg; Testudinella Bory de St. Vincent for Pterodina Ehrenberg; 

 Trichocerca Lamarck for Rattulus Lamarck; Trichotria Bory de St. 

 Vincent for Dinocharis Ehrenberg; Zelinkiella, n. n., for Discopus 

 Zelinka.
