The investigation of bradoriids of South China began at
the beginning of this century. However, it was since 1950's that a lot
of work has been done. A six years of extensive investigation and collection
of bradoriid fossils was made by as many as twenty students and teachers
of Department of Geology at the northwest University in Shaanxi, Sichuan,
Yunnan, Guizhou, Hubei and Guandong Provinces. On the basis of those extremely
abundant materials the second monograph on Bradoriida in the world-"Cambrian
Bradoriida of South China" was published . Although more than 240
bradoriid species of China was described and several of theoretical problems
on Bradoriida were discussed in the book, there are still many problems
remained for further study: 1. The geological range and geographical distribution
of bradoriids in South China are not fully known, and field investigation
ought to be made on more horizons at more localities. 2. The important
microstructural features of bradoriid carapaces were nearly not dealt
with at all. 3. The system atical position of Bradoriida in Crustacea
and its taxonomy need to be restudied. Thus, to solve these problems is
the aim of the present paper.
