Page 600, Rhynchocephalus. (Verrall, in his British Fhes, \'ol. 5, 

 1909, p. 445, separates this yenus from Nemestrina by a character not 

 used by previous writers — the presence of a vein between the third and 

 fifih i)Osterior cells in the latter genus and its absence in the former ; but 

 the one employed by Rondani, Schiner and later continental writers — the 

 multiplicity of accessory cells in the wings of Nemesirina, and their 

 absence in those of the other genus — is a far better character.)
