摘要：
<正> The present paper deals with six new genera,one new subgenus,twenty new species andthree new varieties of trilobite found from the Middle Cambrian formations of North China.Most of them were once enlisted in the writer's foregoing paper(Chang,1957),in which a briefaccount of the stratigraphic sequence has been given.It now seems desirable to describe thosenew forms for further reference.
