irregularly polygonal in outline. In one female larger brown-colored areoles were 
present in addition to the smaller, lightly colored ones. The former were mainly 
arranged in the form of longitudinal ridges and were irregularly star-shaped in 
outline. 
Figs. 36-38. — Three views of head of same. Enlarged. Original. * 
Figs. 39-42.— Four views of head of female P. varius. Enlarged. (After Montgomery, 1898, figs. 83a, 
83b, 84-85.) (The head of my female specimen is not suitable to illustration, and on this account 
Montgomery’s figures are taken, although they are not entirely in harmony with my specimen.) 
Form of male: The anterior end as in the female, but the body more slender. 
The tail lobes are comparatively long and slender, cylindrical in shape, and obtusely 
rounded terminally. Small conical spicules occur on the medio-ventral surfaces of 
the anterior half of the lobes, and short hairs on their anterior surfaces. The elon- 
gate cloacal aperture lies in the medio-ventral line of the body, anterior to the tail 
lobes.
