Polydonta regia, Adams. 
Hab. ? : 
The shell here figured is assigned by Mr. Adams to 
Chemnitz’s 7. regivs, but it is not a satisfactory species. 
It has all the appearance of being a finely beaded, slenderly 
painted, sharply conical form of 7’. maculatus.

Tue warty Trocuus. Shell pyramidally conic, rather 
solid, narrowly excavately umbilicated, greenish- 
white, obliquely flamed with purple-red, flames rather 
broad, distant ; whorls concavely flattened, grained in 
rows, swollen and obtusely tubercled at the margins ; 
base very finely grained, sparingly minutely dotted 
with rose.

It will be seen that each whorl of this species is en- 
circled at the base with a swollen tubercled collar, and 
that the painting is distributed in conspicuous distant lon- 
gitudinally oblique flames, which pass over the basal 
margin.
