Anyone know the correct date of publication of the genus (or more
likely subgenus of Volutopsius) Pyrulofusus>
According to Vaught 1989 Pyrulofusus was described by Mörch in 1857;
P. harpa is (Mörch 1858)... surely he didn't place it in another
genus after already having described Pyrulofusus?
Abbott 1974 gives the authorship as Mörch 1869...
