the ventral plate of the same segment ends In four shorter 

 teeth ; the middle ones are stout, the lateral ones not 

 quite so stout and not projecting- quite so far back as the

 back than the lateral ones, which are very short; the 

 middle notch is angular and small ; the ventral plate bears 

 a broad, not very deep, angular notch at the extremity.
