Wood, the 
Wavy Top- 
shell, Figure 
261, is a south- 
ern species, 
which some- 
times grows to 
a great size. 
The whorls 
are varied by Fig. 20 
numerous wavy ridges, and the base is ornamented 
with beaded cireles. The shell is of whitish pearl, 
and is covered with a brown, fibrous epidermis. 
The opereulum is horny within, while the shelly 
outer part is strengthened by two heavy, curved 
ribs. The cut represents a medium-sized specimen, 
but they sometimes are as much as four inches 
in height. 
Pachypoma inequale, Mart., the Red Top-shell, 
Figure 262, (Pachypoma gibberosum), has a big, 
strong, brick-red shell, with an oval shelly oper- 
culum, somewhat like that of the last species, but 
lacking the ribs. Living specimens are seldom 
found, but dead shells, somewhat broken, are often 
thrown up by the waves, especially around sunken 
ledges. The base of the shell is marked by deep, 
concentric furrows. The shells of this species are 
quite variable, some specimens lacking the seulp- 
tured fillet shown in the engraving below each
