ramidali, olivaceo et prasino tinctd ; anfractibus con-

Tur BLUIsH Trocuus. Shell imperforate, pyramidal, 
stained with olive and green; whorls convexly flat- 
tened, tranversely obscurely grained in rows, some- 
what obsoletely plicately noduled towards the apex; 
base finely grooved, columella callously twisted.

There can be no doubt that the shell described by 
Menke, in his ‘ Mollusca of New Holland,’ with the name 
T. prasinus, is Lamarck’s 7. cerulescens, and it is not un- 
likely that on further research it may prove to be a variety 
of Z. pyramis.

columella calloso-contortéa. 
THE NODULED Trocuus. Shell imperforate, pyramidal, 
slenderly acuminated towards the apex, fulvous-white, 
tinged with rose ; whorls somewhat concavely sloping, 
transversely grained in rows, squamately noduled 
throughout at the lower margin; base finely striated, 
columella callously twisted.

Pyramis noduliferus, Adams. 
Hab. Philippine Islands; Cuming. 
Dr. Philippi follows Chemnitz in regarding this species 
as a variety of 7. dentatus, but it is perfectly distinct. It 
has a closer relationship with 7. pyramis than with 7. den- 
tatus, though differing more from it in general aspect.

SHARPLY-ANGLED TRocuus. Shell rather obscurely 
umbilicated, pyramidal, sometimes angled, sometimes 
rounded at the base, white, obliquely largely flamed 
with crimson-red; whorls transversely grained in 
rows, grains oblique, rather papillose, irregular; base 
impressly striated, intermediate ridges rather flat, 
filleted with deep crimson-red, columella callous, 
slightly twisted.

This fine species may be readily distinguished from any 
other by its broadly flowing crimson flames.

THE PYRAMID Trocuus. Shell imperforate, pyramidal, 
whitish, stained and obliquely variegated with green; 
whorls convexly flattened, transversely grained in 
rows, grains more prominent towards the apex, upper 
whorls obsoletely plicately noduled; base finely 
grooved, columella callously twisted.

An extremely variable species, more or less green or 
olive-green in colour, sometimes almost colourless, with a 
greater or less development of grains and nodules.
