very cogent reasons given by Lord Walsingham* for adopting the 

 Teutamen, but merely state that I heartily agree with them. I 

 should certainly adopt the date 1806, from the showing of Mr 

 Scudder in his Historical Sketch of the Generic Names Proposed for 

 Butterflies, p. 98, and from that of Lord Walsingham in his accom- 

 panying paper."

" No, the genera of Hiibner's Tentamcn should not be accepted. 

 The evidence in Hiibner's published works seems to indicate that 

 this sheet was prepared somewhere about 1806, and \\'as primarily 

 a scheme for his own guidance— a tentative classification, such as 

 almost every student has at times made in the groups which he was 

 studying. Hiibner printed his scheme, and, apparently, sent out a 

 few copies to correspondents to obtain suggestions or criticisms or 

 for their information — much as if I should by means of a hekto- 

 graph or other mechanical device multiply some scheme of my own 

 and should send it about as a suggestion. It might induce some 

 co-worker who found the scheme feasible, to adopt parts of it, just 

 as Ochsenheimer did. It is in this light that I think that author's 

 sentence ' daher konnte ich frliher nichts davon aufnehmen ' should 

 be construed. There is no sufficient proof of ' publication.' 



Canon XXIV. of the A. O. U. Code, above referred to, reads : — 

 ' A novien Jindiivi is to be rejected as having no status in nomencla- 

 ture.' It is remarked in comment or explanation, that ' A name, 

 generic or specific, which has been published without an accom- 

 panying diagnosis, or reference to an identifiable published figure or 

 plate, or, in case of a generic name, to a recognizably described 

 species, is not entitled to recognition, being merely a name, and 

 therefore having no status in nomenclature.' 



Under a very liberal interpretation of this, and assuming that 

 the Tentavien was really published, the names might stand, because 

 the generic terms are associated with those of known species. But 

 except to one familiar with the associated species no information is 

 conveyed, since no author is cited for the specific name, and no 

 reference is made to any publication where any species is recog- 

 nizably described. As a whole, it is a bare outline of a scheme of 

 classification and nothing more ; with not a clue to the characters 

 upon which it was based, and not a syllable that would enable 

 a student in Africa, not thoroughly familiar with the European 

 fauna, to place a solitary specimen. It seems to me hardly possible 

 to recognize Tentavien names."

" Certainement pas. Cet ecrit insignifiant est sans valeur, ne 

 porte pas de date et rien n'indique qu'il soit veritablement public.
