 pairs, not projecting nearly as far caudad, short and narrow, each 

 with lateral notch; second and third pairs of lobes narrow, bluntly 

 rounded, each with lateral notch; pectinae longer than lobes, una-

 jection near middle of each lateris and with seta near its 

 lateral margin; median pair of lobes rounded, prominent, 

 slight lateral notch; second and third pairs of lobes 

 smaller, lateral margins oblique, lateral margin of third 

 pair serrate; pectinae subequal in length to lobes, arranged
