The foregoing are some selected examples from the synonymy of the best form of this 

 species. 



Characters. — Shell oblong, sub-compressed; margin rounded; segments ventricose. 

 ColoiiT, white to yellowish-brown. Length, ^th inch. 



The common typical robust Miliola, observed by Plancus, Gaultieri, Fabricius, 

 Schroter, and indeed, by nearly all the early authors on marine organisms, was first 

 properly described by Linne, in the tenth edition of the ' Systema Naturae' (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 glol)ose forms of Q. seminvhim.
