PART II. SYSTEMATIC PALEONTOLOGY 



GENERAL STATEMENT 



Not all the species of trilobites described from the Upper Cambrian 

 of Tennessee are treated in this paper. With few exceptions, only those 

 collected by the author from measured sections and hence contributing 

 to the knowledge of the faunal succession are discussed herein. 



Type catalog numbers and type localities for previously described 

 species are given only when the types are from the southern Appala- 

 chians. 



Unless otherwise stated, all the described and illustrated specimens 

 are preserved in limestone, and show the outer surface of the test, on 

 which the description is based. 



The author's localities are often given only by their numbers in this 

 descriptive part; their topographic position may be readily identified 

 from the locality list, the stratigraphic position from the descriptions 

 of the sections. 



All the types and other figured specimens collected by the writer 

 were deposited in the U.S. National Museum collections. All the Mu- 

 seum numbers beyond 144000 are listed in Paleozoic catalog No. 30.

Common almost everywhere in the fossiliferous beds at the top of 

 the Maryville limestone and the overlying basal Nolichucky shale 

 (Cedaria zone) . 



Occurrence. — Type locality for K. simplex is U.S.N.M. 27d ( = 

 author's locality cnd/1) ; red beds at the base of the Nolichucky E. 

 of Rogersville. Type locality for K. harlanensis is U.S.N.M. locality
