This sjx'cies on account of its rather imperfect description seems to 

 have caused considerable trouble in regard to its identitication, Euro 

 pean writers considering it the same as glaKsccscens Koch, aiul closely 

 allied to complanatus of Europe, in which they liave been correct, while 

 Am«'rican jiuthors liave referred to it another species — the monilittris 

 of Koch. This latter si)ecies has the lateral carina' finely denticul.ite 

 and the scjuamifotin divisions much eh'vated, while in .scrratKn, jiccoid 

 ing to Say's tU'sciiption, the latt'ial carina* have only 3 or 4 denticula- 

 tions an«l the squamiform divisi<uis low.

This well-known species, which was afterwards described as new by 

 Koch and made the type of the genus iSryt<>m>tu.s, shoidd now stand as 

 Scjjfonottis/iraHulatKN (Say). 



9. Polyeenus fasciciilatus Say. .lourn. Acad. Nat. Sci. Phila.. 108, 1821. 

 This rare species still retains the name given to it by Say. 



Its habitat is from Massachusetts to Indian Territory, and it does 

 not seem to be found in the North Central States.

SpinijHs has always been identified by European and American 

 authors with th«> Uthobhis f<n\ticatuH of Linnanis, but on account of the
