Conus lyratus
(Marshall,
1918)
Conus
marshalli (Finlay, 1926)
Description.
Shell of moderate size, 28 mm. by 10 mm. Spire short, about
one-fifth the length of the body-whorl. Five whorls, each slightly convex in outline.
Each whorl rising by a decided step from the anterior suture. Aperture narrow
but expanding slightly anteriorly.
Ornamentation: Whorls smooth except for numerous distinct lines
of growth which extend completely across them. Body-whorl with distinct spiral
lirae over its whole surface, though they are more distinct in the anterior
than in the posterior portion. Lines of growth on the body-whorl are not
numerous and not distinct. A single specimen, in good condition. Type in the Wanganui
Museum (2).
Conus
marshalli is a synonymous
of Conus lyratus, but the change of the name was unnecessary (3).
