Imhof, in Zool. Anz., vol. 11, 1888, p. 171, used two names, Gas- 

 tropus ehrenhergii and Gastropus stylifer, giving only one description, 

 without any clue to the name intended for it. This was not given 

 until 1891, Zool. Anz., vol. 14, p. 37, where he informs us that Gas- 

 tropus ehrenbergii is Euchlanis lynceus Ehrenberg renamed. Conse- 

 quently, Gastropus stylifer must be dated 1891.
