The Ordoviciau System is well developed in Hule area of Ningkuo, Southern Anhui. The type localities of two famous formations, the Ningkuo Shale and the Hulo Shale, are located in this area. In the past the Xianchangian (Tremadocian) graptolites of the Lower Ordovician were not discovered in Southern Anhui. In 1981, the present authors collected a considerable amount of Xianchangian graptolites from the top part of the Xiyangshan Formation, formerly considered to belong to the Upper Cambrian. These graptolites are described in this paper, including 6 genera (Staurograptus, Anisograptus, Adelograptus, Aletograpus, Clonograpus and Dicyonema) and 14 species and subspecies, among which a new species and a new subspecies are established. It is first reported that Xianchangian graptolites are discovered in Southern Anhui, and that greatly enriches the biostratigraphical data in this area. Based on the vertical distribution of these graptolites, two graptolites zones, the Staurogaraptus zone and the Anisograptus-Clonograptus zone, are established. They may be correlated with the Staurograptus-Anisograptus zone (X_1) and the Aletograptus-Triograptus zone (X_2) in Taishan, Guangdong Province respectively.

Prof. Xu Jie's(Singwu C. Hsu) a famous geologist and palaeontologist, has been studying stratigraphy and palaeontology for more than fifty years. His research work on graptolites with their related strategraphy is particuliarly important in building up a foundation for further study of the graptolites and the graptolite-bearing strata in China.Since 1930, Prof. Xu has published a series of valuable papers on grap-tolites, and also reported and described a great number of graptolite species and established many graptolitic formations and graptolite zones.In his monograph entitled "THE GRAPTOLITES OF THE LOWER YANGTZE VALLEY" (1934), the most imporatnt work on the graptolites of China, Prof. Xu described in detail more than 90 species and subspecies of Ordovician and Silurian graptolites belonging to 19 genera, all species with remarkable illustrations in very fine figures drawn by himself.The Tanchiachiao, Ningkuo, Hulo and Yuchian formations with graptolite zonations in southern Anhui and western Zhejiang proposed by Prof. Xu have formed the foundation for the study of Ordovician stratigraphy in south China, with the Tremadocian graptolites of the Tanchiachiao formation, the Arenigian and Llanvirnian graptolites of the Ningkuo formation, the Llandei- lian and Caradocian graptolites of the Hulo formation and the Ashgillian graptolites of the Yuchian formation as the main representtiaves of the gra-ptolite fauna of the S. China Type.In Central China (or the Yangtze Region), the Tremadocian graptoliets of the Ichang formation were first described by Prof. Xu (Hsu and Ma, 1948), who consequently established the Acanthograptus sinensis zone in the upper part of the formation, which includes the graptolites belonging to the grap-tolite fauna of the C. China Type. He also described the Silurian graptolites of the Kaochiapien formation in the Lower Yangtze Region and a few species from the Lung mac hi formation in the Upper Yangtze Region.In Northwest China Prof. Xu described two important Lower Ordovician graptolite faunas from Tsaidam, Qingkai and Guozigou, Xinjiang, both with closer relation to the graptolites of the Ningkuo formation of S. China,belonging to the S. China Type. In his study 18 forms belonging to 10 genera were described from the Lower Ordovician of Tsaidam with the following three characteristic features recognized. 1) This fauna comprises a considerable number of forerunners; 2) It consists of a number of thin and delicate forms; 3) It appears to bear a distinct regional character. His description also includes 55 Lower Ordovician species belonging to 16 genera of the Guozigou Area with three graptolite zones established in ascending order: 1) the T. (E.) approximatus zone, 2) the D. "protobifidus" zone and 3) the Oncograptus upsilon-Cardiograptus morsus Zone, among which the last graptolite assemblage zone is similar to the Isograptus caduceus zone of Texas, N. America, comprising the elements mainly of the Oncograptus zone (N5) and the Car-diograplus zone (N6) in association with some species of the D. abnorms zone (N4) and G. austrodentatus zone (N7) of S.China and Australia. Prof. Xu is of the opinion that the Oncograptus upsilon-Cardiograptus morsus zone as well as the I. caduceus zone is a peculiarly mixed zone, in which the graptolites are not endemic forms, but are immigrant from the faunal center located in S. China to Australia.Prof. Xu discussed thorougkly the evolution and classification of the families Phyllograptidae, Sinograptidae, Glossograptidae, etc. Based on the characters of the thecae and the arrangement of the stipes in Trigonograptus, he compared this genus with Phyllograptus and placed it in the family Phyllograptidae in 1931. Later in 1961, after a careful examination of the Trigo-noraptus specimens in relief, he found that the genus is composed of four stipes just as Pseudotrigonograptus, the latter being considered as syuomymous with Trigonograptus, and therefore he pointed out that Trigonograptus (rec- ently replaced by Pseudotrigonograptus) is evolved from Phyllograpius due to th
