TRICHOCERCUS Cuvier. 



In his Lepons d'anatomie comparee, vol. 1, 1800, Cuvier gives in 

 Tableau IX a list of systematic names with their vernacular (French) 

 equivalents. Among these is: Trichocerques- Tnc^ocgrcws. This is 

 apparently intended for Les trichocerques, p. 660 of his Tableau 

 elementaire de I'histoire naturelle des animaux. 1798, which was 

 published without any systematic name. The passage is as foUows : 



Les trichocerques. 



Sont tres-voisines des brachions et des rotiferes; elles ont une queue a peu pres 

 semblable, quelquefois fort longue, ou double, oufourchue; maisiln'y apointd'ecaille 

 eur le dos, et la partie anterieure du corps est seulement garnie d'especes de polls, et 

 n'a point d'organe rotif&re.
