Conchoid of Nicomedes: Also known as

Some sources suggest that the conchoid of Nicomedes can also be referred to as a cochloid.

However, this usage can be confused easily with the cochleoid which some dictionaries give cochloid as an alternative for.

Others refer to it as merely a conchoid, but that term is best used to refer to the more general object of which the conchoid of Nicomedes is an example.
