Another good source of information on Conus scalaris is:
West American Mollusks of the Genus Conus - II
G. Dallas Hanna, January 28, 1963
Occasional Papers of the California Academy of Sciences, No. 35, 103
pages, 4 figures, 11 plates
The color plates are very useful in comparing species. The holotypes of
C. scalaris, C. regularis, and C. gradatus are figured.
