It is probable that Lamarck's Trichocerca Cuvier, p. 394, Syst^me 

 des animaux sans vertebres, 1801, is intended for this also. The 

 description, given below, seems to indicate this. 



XLIV Genre. Trichocerque. Trichocerca Cuv. Corps tr^g petit, transparent, 

 submultiforme, pourvue d'une queue simple ou fourchue, et de cils ou de poils dana 

 sa partie int^rieure. 



As Cuvier gives no species, and his description would fit a great 

 many rotifers, it must probably be considered unrecognizable, and 

 Lamarck's name given preference, as it is defined by the type, Trichoda 

 rattus Miiller.
