 p. 166, pi. 13. figs. 4a-4c. 



This also is represented by a single example too poor to be defi- 

 nitely placed. No part of the margin is complete, and so far as pre- 

 served there is nothing to distinguish it from B. scrutator or B. oculata. 

 The type being unidentifiable, the name should be dropped. 



Occurrence. — Lower Cambrian (Lower Etcheminian, division Elc) : 

 Dugald Brook, Escasonie, Cape Breton.

 p. 204 (gen. ref.); Canadian Rec. Sci., vol. 8, 1902, p. 452. 



Original description. — Suboval, elongate, nearly* straight along the 

 back, somewhat narrow towards the anterior end, flattened along the 

 hinge line, and turned towards the ventral margin. There is a short 

 broad vertical furrow at the anterior edge of the hinge line, whose 

 length is about one-third of the whole length of the valve. 



Sculpture. — This consists of closely set pits, just visible to the 

 naked eye. 



Size. — Length about 4 mm; width about 2 mm; height of valve 

 about IK mm. Matthew's type was not present in his collection when 

 studied by us, so that we have to leave the status of the species un- 

 certain. 



Occurrence. — Lower Cambrian (Hanfordian, C161 ) : Hanford Brook, 

 New Brunswick. 



BRADORIA FENNICUS (Wiman) 



Plate 3, Figure 17 



Aparchites fennicus Wiman, Bull. Geol. Inst. Upsala, vol. 6, pt, 1, 1902, p. 46, 

 pi. 3, fig. 51. 



The illustration of Aparchites fennicus Wiman as reproduced on 

 Plate 3 certainly shows the relationship of the species to American 

 forms like Bradoria scrutator and B. henepuncta. 



Occurrence. — Cambrian (gray quartzitic sandstone) : Aland, Sweden.
