274 IOWA GEOLOGICAL SURVEY 



A study of an extensive suite of material from the Lower 

 Carboniferous of Albert county, New Brunswick, including the 

 originals of Dr. C. T. Jackson's figures and descriptions, shows 

 that a minute form apparently closely allied to the Scottish E. 

 striatulus is present in this horizon and locality, where it ac- 

 companies E. browni and the several species of Ehadinichthys 

 already noticed in the preceding pages. The new form, for 

 which the title of E. elegant ulus is not inappropriate, may be 

 readily distinguished by its small size, slender and graceful pro- 

 portions, and decidedly prominent, even coarse, details of scale 

 ornament. The scales are traversed longitudinally by a num- 

 ber of closely crowded raised ridges, smooth, continuous, glis- 

 tening, and the whole presenting an appearance not distantly 

 recalling Ptycholepis, from a much later horizon. In addition, 

 the lateral line is very conspicuous. The head and fin structures 

 are not clearly revealed in any individual that has thus far come 

 to light, but the general resemblance to the little fish made known 

 by Traquair from Eskdale and East Lothian* necessitates its 

 reference to the same vicinitv.
