Art. XIII. — Notes on Victorian Rotifers. 



(With Plates XII and XIII.) 



By H. H. Anderson, B.A., and J. Shephard. 



[Received December 11, 1891.] 



During the last few months we have been working together 

 on the Rotifera, and as one of us is leaving the colony, we 

 have determined to record the results of our observations 

 somewhat earlier than we otherwise should liave done. Of 

 one of the new forms, only a single specimen has been seen, 

 and that by only one of us ; but we have recorded this and 

 other observations in the belief that the}^ will be of use to 

 other observers. Mr. Anderson has devoted his attention 

 principally to the Rhizota, Mr. Shephard taking the other 

 orders ; but in nearly all cases we have been able to show 

 each other, and to examine together, the various species that 

 we have met with. In the case of new forms, seen by only 

 one, we have indicated the fact by the use of brackets and the 

 initials of the observer; we have not considered it necessary 

 to do this in the case of known forms. We have ap{»ended to 

 the names of the species the places where we found them, 

 and what other infoimation we thought might be of scientific 

 interest, but have preferred to err on the side of brevity, 

 rather than to insert unnecessary matter. Our authority 

 throughout has been " Hudson and Gosse," which, with its 

 supplement, is a complete record of all observations up to 

 the date of its publication, three years ago.
