The Gloomy Scale 
15 
“There are seven club-shaped thickenings of the body wall upon 
each side of the meson, which are arranged as follows: One terminat¬ 
ing near the lateral margin of the first lobe; this extends anteriorly but 
a short distance beyond the lobe. One appearing to be a prolongation of 
the mesal margin of the second lobe; this extends anteriorly to a point 
laterad with the anus. One terminating between the second and third 
lobes; this is linear, inconspicuous, and sometimes obsolete. One 
terminating at the base of the plates between the second and third 
lobes, and also one terminating at the base of the plates between the 
third lobe and the thickened lateral margin; these two are the largest, 
and extend anteriorly the farthest of all the thickenings. One terminat¬ 
ing at the mesal margin of the third lobe, and one at the mesal end of 
the thickened lateral margin of the segment.

“The plates between the median lobes and between the first and second 
lobes of each side are very small and often obsolete; there are two small 
irregularly branched plates between the second spine and the third lobe, 
and also two similar plates between the third spine and the mesal end of 
the thickened lateral margin.
