Mr. Claude Morley's Descriptio7i of 



undoubtedly entire. Through the centre of the medius 

 runs a transverse nervure, termed the BASALIS, which is 

 not always continuous, but sometimes coalescent for a 

 greater or less distance with the medius. From the 

 supra-basal a nervure runs more or less straightly to the 

 external margin of the wing in a direction somewhat 

 parallel with the radius; this is the cubitus, and it is 

 attached to the radius by one or more transverse nervures, 

 termed the intercubiti, since they divide up the cubital 

 cell into two or more sections. Parallel with the cubitus 

 and below it is the analis, also extending to the outer 

 margin, but rising at some point on the externo-medius. 

 Lastly, one or two recurrent nervures are seen, of which 

 the first always runs from the point G in the medius to 

 some point on the cubitus, and the second, when present, 

 from some point on the analis to the cubitus further from 

 the base than the first. 



Thus we find but nine main nervures and two series of 

 transverse (the intercubiti and recurrenti) in a typical 

 wing. It is, consequently, remarkable to what extent 

 these have been renamed by the various authors, and 

 gives one some idea of the chaos from which the law of 

 priority — unfortunately inapplicable here — has saved zoo- 

 logical nomenclature.
