T. labio. T. exumbilicatus ovatus striato-tuberculatus, labio dentato.
The erroneous figure of d'Argenville was not cited; "variegata" was the earlier reading of "marmorata"; "aliquot" of "et punctis"; "externo" of "margine". Linnæus himself had enlarged the account of the inner lip from the earlier "postice sinu excisum" to its present length.
T. zizyphinus. T. umbilicatus conicus, striis papillosis.
This is clearly not the imperforated zizyphinus of the 'Systema.' Gualtieri was not referred to; "ambitu marginati", and "in aliis clausus", were not in the copy: "columella parum obliqua" was an addition in the Linnean handwriting.
T. telescopium. T. exumbilicatus pyramidatus, striis exaratus; labio postice recurvato, spirali, integro.
"Bon. 92", and "Klein 26. Pseudotrochus striatus", were the additional synonyms of the MS.
T. dolabratus. T. umbilicatus, labio postico recurvato sulcato, ovato-pyramidalis, glaber.
The whorls were at first called imbricated. The "basis rotundata", and "in superioribus vero unica", had been added by Linnæus.
