Twelve New Species of Rotifer a. By P. H. Oosse. 367 



Corrigenda et addenda. 



Monura micromela, Gosse (this Journal, ante p. 7). Since this was 

 pubhshed I have seen the toes widely expanded. The species must, 

 therefore, be transferred to Colurus. 



Furcularia marina, Duj. (H. & G. Kotif., ii. 44). I have lately 

 seen two pectoral eyes, pale-red, well-defined, one on each side of (but 

 behind) the mastax. The species must, therefore, be transferred to 

 Bistem^na, with which genus the trophi agree. 



TriojpJithahnus dor&ualis, Ehr., a noble species, I have lately found 

 in a pool near my own residence, agreeing accurately with Ehrenberg's 

 figure. 



Anurxa 4:-dentata, Ehr. I have identified in water sent me by 

 Mr. Bolton from Birmingham.
