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 Burgess Pass, near Field, British Columbia, Canada.
Well known fauna with numerous specimens of exceptionally preserved fossils of crustacea, annelids, sponges, algae, and many other forms. Characteristic trilobites: Neolenus, Dorypyge, Elrathia, and others.
67g.—Lower Cambrian, Eager formation: Brown and red (weathered) shales, 5 miles northeast of Cranbrook, British Columbia, Canada.
Contains an upper Lower Cambrian Mesonacid fauna, that includes some new elements.
25.—Lower Cambrian: Parkers Quarry, Georgia, Vermont.
Contains typical Mesonacid fauna.
12x.—Lower Cambrian, Kinzers formation: Getz Quarry, 1¾ miles north of Rohrerstown, Pennsylvania.
Contains the Vermont Mesonacid fauna.
12w.—Lower Cambrian, Kinzers formation: ¼ mile west of Fruitville, 3 miles north of Lancaster, Pennsylvania.
Same fauna and bed as 12x.
—Middle Cambrian: Mount Tang-shih-ling, near Yen-tai colliery, 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. Riuji Endo, in the course of his field studies in the regions south of Mukden and they form a part of large and excellent collections whose 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 Manchuria.
