*) Shell similar to P. zilida, but much smaller and less discoidal, the 
spire being more elevated and the last whorl higher: the color of the upper 
whorls (the last and usually a small part only of the penult whorl being 
excepted), varies from a deep crimson to a bright orange red, with an 
opaque white line along the suture. In all other characters this shell so 
closely resembles P. mida, that I have long hesitated whether I should 
propose it as a distinct species. 'The peculiarity of form appears to be ab- 
solutely constant in the individuals (about 30), that I have seen: that of 
color fails partially only in a very few, which appear to have been bleached 
by exposure. — Greatest breadth 0,2; least breadth 0,18; height 0,12 inch. 
(Ad. l e.) 1 
**) Shell globular: pale yellow and whitish: smooth and shining: apex 
very obtuse: spire well elevated, with very convex outlines: whorls five, 
quite convex, with the suture not impressed: last whorl very large and 
high: aperture longitudinally lumate: labrum sharp, moderately thickened 
within, without teeth or lamellae: columella moderately produced nearly in 
the direction of the axis of the shell, with one sharp prominent nearly 
transverse plait: labium with a very prominent and sharp revolving plait 
near the columella, — Mean divergence about 110?; length of aperture 0,15; 
total length 0,21; greatest breadth 0,24; least breadth 0,2 inch. (Ad. l. c.)
