Peng Shanchi, Loren E. Babcock and Lin Huanling (editors)
2 Volumes. Text in English.
The Wulingshan Mountain region of northwestern Hunan and eastern Guizhou provinces, China, contains some of the most complete and fossiliferous strata known in the upper part of the Cambrian. Easy access to good exposures has helped make this area the subject of numerous systematic, biostratigraphic, lithostratigraphic, chemostratigraphic, and sequence-stratigraphic studies.
The purpose of this two-volume monograph is to document the polymerid (non-agnostoid) trilobites from the Huaqiao Formation of northwestern Hunan. A total of 196 species, some in open nomenclature, are reported, including a large number of new genera and species.
Volume 1: Corynexochida, Lichida and Asaphida, 332 pages.
Volume 1 contains general geological information concerning the Huaqiao Formation of northwestern Hunan, lithostratigraphic data, biostratigraphic zonation, detailed descriptions of three stratigraphic sections, and the systematics of corynexochid, lichid, and asaphid trilobites.

Volume 2: Ptychopariida, Eodiscida and Undetermined Forms, 354 pages.
Volume 2 contains systematic treatments of the ptychopariids, eodiscids, trilobites of uncertain affinity, and some undetermined sclerites. All illustrated specimens were coated with black ink and then magnesium oxide before being photographed, all are preserved in limestone.
