 Harlani Green. 



The author remarks that among the American relative of Pora,lit.\ii!is iliirlani the 

 most nearly related to the broad form is P. regini Matthew, from St. John t'toup; 

 also P. Bennett! Salt. 



The nearest relative of the narrow form is the Paradoxides fpinosus th° Bohcmi.in 

 species. Many }ears ago Linne Mus. Tessiniaimi, 1753, p. 98, pi. i, desciilicd under 

 the name of Entornolit/ius paradoxus a trilobite of a wide form, about 6^4 inches long. 

 Brongniart describes it as Paradoxides Tessini, using the narimv form of W'ahlen- 

 berg's pi. 1, fig. 1, which he has copied. 



The original, quoted from Dimbo, Sweden, by Linne, has never been again found 

 in Sweden, the specimen may be one from Boston, Mass., obtained from the Boston 

 Wharves by some Swedish naturalist in early tlays, the stones from the Braintree quar- 

 ries were used in the Boston Harbor.
