GEOGRAPHICAL DISTRIBUTION 



The fossils described in this paper were secured from five general 

 localities at four widely separated places in North America and 

 Asia. For greater convenience and to prevent numerous repetitions 

 precise descriptions of the several localities are grouped together in 

 the following paragraphs : 



List of localities 



35k. — Middle Cambrian, Burgess shale: On west slope of the ridge 

 between Mount Field and Wapta Peak, 1 mile northeast of

 served fossils of Crustacea, annelids, sponges, algae, and many other 

 forms. Characteristic trilobites : Neolenus, Dorypyge, Elrathia, and 

 others.

 some new elements.

 Contains typical Mesonacid fauna. 



12x. — Lower Cambrian, Kinzers formation: Getz Quarry, 1% miles

 Contains the Vermont Mesonacid fauna. 



12w. — ^Lower Cambrian, Kinzers formation: ^4 i^ils west of Fruit- 

 ville, 3 miles north of Lancaster, Pennsylvania. 

 Same fauna and bed as 12x. 



— Middle Cambrian: Mount Tang-shih-ling, near Yen-tai col- 

 liery, Liau-tung, Manchuria, China. 

 Dorypyge fauna. 



— Middle Cambrian: Huo-lien-chai, Liau-tung, Manchuria, 

 China. 



Fauna same as preceding. 



The specimens from Manchuria were collected at two near-by 

 places by Prof. Eiuji Endo, in the course of his field studies in the 

 regions south of Mukden and they form a part of large and excellent 

 collections Avhose species are now being described by Doctor Endo 

 and myself. Both localities are located along the railway south of 

 Mukden not far from Yen-tai, hence about in the center of Man- 

 churia.
