Note

As has been documented in other item listing on this site, I have proposed a new form of armeniaca being Cypraea armeniaca "verawestralis". This name has no taxonomic standing but is the name I have elected to refer different shells we have been finding in very limited numbers on our south coast between Walpole through to the east of Esperance. These shells differ significantly in colour and shape from both andreyi and GAB armeniaca. In the area off the very southwest corner of Western Australia I believe these shells have merged with classic andreyi as sea levels have risen during the current interglacial period to produce a hybrid population. Armeniaca collected off Augusta fall into two very distinct colour forms. While all shells are very heavy and fit as andreyi on mass ratio, they have either china white bases or rich pink orange bases. In addition shells are often dark in colour with dense tan burgundy spots. Both of these traits are not present in west coast andreyi but are features of the "verawestralis" form. This specimen was ROV collected from 82 metres of water south of Israelite Bay, Western Australia. A heavy shell with high domed mottled dorsum, apricot sides and siphons with matching base. Graded Fine++ as there is a sand inclusion in the nacre on columnar side and a growth fold on its columnar dorsum. This is the first time we have collected an armeniaca from this area and in my opinion are similar to diprotodon.
