The common typical robust MMliola, observed by Plancus, Gaultier, Fabricius, 
Schroter, and indeed, by nearly all the early authors on marine organisms, was first 
properly described by Linné, in the tenth edition of the ‘Systema Nature’ (1758), under 
the name of Serpula seminulum. There are perhaps few members of the animal kingdom 
which have so often received the attention of naturalists, or that have been named and 
’ Figs. 56, 57, 58, of the same plate, seem to be more globose forms of Q. seminulum.
