GEN. APUS, Schaeffer. 



1756. Apus, Schaeffer, Mon. d. krebsartige Kiefenfiisse, p. 131. 



Owing to its date, Schaeffer's work is not accepted by 

 Sherborn in his Index Animalium as authorising the use of 

 this generic term under the rules for Linnean nomenclature. 

 But Professor F. Jeffrey Bell, Ann. Nat. Hist., Ser. 7, vol. v., 

 May, 1900, argues " that Schiifer's generic name stands on 

 an equality with those of Brisson or Artedi, which are 

 expressly named in the note to law 2 of the British Association 

 rules." The point is that binomial designations may be 

 accepted from authors who had the sagacity to be binomial- 

 ists even before the Epoch 1758. Should this ruling not be 

 allowed on Schaeffer's behalf, it seems that Apos, Scopoli, 

 Introd. Hist. Nat., p. 404, 1777, will have to be substituted 

 for the crustacean genus, while Apus is given up to the birds.
