as first described by him, being specifically identical with 

 it, and his name is consequently prior to all those which 

 I have enumerated ; but the reduplication of the same

 objectionable. V.pusilla, as well as the present species, 

 were confounded by Montagu in the subsequent part of 

 his description. I fear that this little episode will 

 interest none but bibliographical naturalists.
