M. ricinus. M. ecaudatus, ore utrinque dentato.
"Æqualibus, ad labium majoribus" was not in the copy.
M. capitellum. M. ecaudatus ovatus, columella rugosa, labio edentulo, superficie inermi rugosa.
"Alba" followed "edentula", and "Umbilicus ad basin" terminated the description in the original: the word "striis" was a subsequent introduction.
M. turbinellus. M. ecaudatus, turbinatus, columella dentata, spinis explicatis.
The printed additions are "anteriores", "nodulosa", "alba", "Cauda vix ulla", and "Variat colore albo spira longiore".
M. Ceramicus. M. ecaudatus, utrinque acuminatus, columella dentata, spinis conicis.
"Rumph. t. 49. f. L." was an unpublished synonym.
M. nodus. M. ecaudatus ovatus, labio denticulato.
As "Gualt. t. 28. f. R." was quoted, and "aut nigris, conicis, obtusiusculis" (a character which probably belonged to some distinct species erroneously supposed to be a variety) was not inserted in the manuscript, I feel convinced that the Purpura hystrix of authors was the species designed in the 'Museum Ulricæ.'
