W F. Kn-by, in the ' Zool. Record' for 1871, states that if my 

 B. octocula is- B. formosa, the latter specific name will take priority 

 Upon what grounds he comes to this conclusion I am unable to 

 imagine; for it must be manifest to every reasoning being that the 

 Jan.-March number of the ' Stettiner Zeitung' can only have been 

 procurable on the 1st of April at the earliest, whereas mv paper 

 appeared on the 1st of January. " V V
