Taxonomic notes: This species is listed in Kay, 1979 as Turbonilla lirata. It is probably also listed in Severns, 2011 as Turbonilla lirata, Turbonilla kauaiensis and Turbonilla oblectomentum (the illustrated shells appear to be within the range of variation for T. kahoolawensis and, in our opinion, Kay was probably correct in synonymizing the Hawaiian material).
