MARINE S PI ELLS OF WEST COAST OF NORTH AMERICA 
It is solid, but thinner than H. rufescens. The outside is a uniform dull 
reddish-brown. It is sculptured with rounded spiral lirae, nearly equal in 
size, 30 to 40 in number on the upper surface. At the rows of holes there 
is an angle, the surface below it sloping almost perpendicularly to the colu- 
mellar edge, and having an obtuse keel about midway. The spire does not 
project above the general curve of the back. Inside dark, mostly blue and 
green with dark coppery stains, pinkish within the spire; the muscle 
impression painted in a peculiar and brilliant pattern, like a peacock's tail. 
Columellar plate wide, flat, sloping inward. Cavity of the spire small, 
almost concealed. Perforations rather small, elevated, circular, about five 
in number. Length, 170; width, 130; convexity, 48 mm. (Tryon and 
Pilsbry, Manual of Conchology.)

Shell of an oval form, considerably flattened, and with about two and a 
half whorls; color, dark brick red, with occasional mottlings of pale bluish 
green; holes, four in the young to six in the adult; sculpture of fine, some¬ 
what irregular spiral threads, crossed by fine, close, slightly elevated, sharp 
concentric lamellae, and a few small obscure wavelets which radiate 
obliquely from the apex; nacre rather pale, with pink and pale-green reflec¬ 
tions, but much less deep in color than the typical fulgens. 
This variety differs from the type in its more elongate and flattened 
form, its constantly finer spiral threading, and its paler nacre. The con¬ 
centric lamellation is sometimes undeveloped on the young shells. It has 
the same number of holes as the type. (Stearns.)
