inwards, and none of them arc bidentate. 
The anterior stigmata or spiracles {si. /, 3, j ) are branched ; each 
with ten to twelve relatively large orifices ( st. j). The posterior 
stigmata (fig. 13, st.) are large obconical projections of brown chitinr. 
each presenting three darker transverse slits, partially closed by a 
fine transverse grating. 
The posterior segment (fig. 13) bears along its margin four 
conspicuous bilateral papillae {m.p.) t of which the median and third 
pairs are much the largest; the second and fourth pairs arc modi 
smaller; all are sharply attenuated and hear faint traces of 
segmentation.
