Rotifera of the Family A splanchnida3.

published by Bartscli in a very interesting 

 sufficiently known *. 



In this the genus Ascomoiylia is placed 

 group Loricata, in which it immediately 

 precedes the genus Sdpina. This course 

 appears to me better than that which con- 

 sists in combining the AscomorplicB and 

 the Asplanchna', in the same family. At 

 any rate, until we have fuller information, 

 it is preferable to leave these Rotifera 

 amongst the forms incertcB sedis. 



The following gives, in a few lines, the 

 complete synonymy of the genus Asco- 

 morpha^ which denomination must be 

 adopted as the earliest in date, as well as 

 the specific name of ecaiidis^ first employed 

 by Perty for A. helvetica. I do not think 

 that there is any reason for uniting the 

 three species at present known, after the 

 example of Hudson and Gosse; in any 

 case, A. safoi??s, Bartscli, appears to me to 

 be a very distinct type.

Severtil distinguished Hungarian zoologists, Toth, Bartscli, Vejdovsky, 

 and, more recently, Von l)aday, have successfully studied the Rotifera. 

 It is to be regretted that these naturalists have thought fit to publish 

 most of their works in Hungarian. By this means they remain beyond 

 the reach of the scientific public. To act in this way out of patriotism is 

 certainly an error, the consequence of which is to narrow greatly th,<? 

 renown of the national savants.
