請問一下各位大大,高貴竽螺(Conus nobilis)和Conus cordigera不是同種異名嗎?可是在香港的網拍時常可以同時看到這兩種貝殼在拍賣,可是我實在是看不出這兩者有何不同.可不可以請收集竽螺的前輩解答疑惑,謝謝!

There isn't a lot of difference between the two, and like everything in taxonomy it comes down to a matter of opinion whether C. cordigera deserves full species status. I tend to follow Rockel, Korn & Korn (Manual of the Living Conidae), who do recognize C. cordigera as a species. Their descrïption states:
"C. cordigera closely resembles C. nobilis. The latter species differs mainly in its non-tuberculate early and carinate later postnuclear whorls, and its coarse alternating brown and white spiral lines within the larger solid brown areas of its last whorl". Not exactly a long list of criteria for separating the two!
