io6 The Ottawa Naturalist. [July 



from the upper Pottsville of the Appalachian province described in 



manuscript by the writer as a variety of A'europ/eris Schlehani 

 Stur. 



Locality. — "Fern ledg-es," Lancaster formation, near Sr John, 

 New Brunswick. 



The type of the species is with No. 73 (391) in the collections 

 of the Geological Department of McGill University, Montreal, 

 Canada. 



RELATIONS AND SYSTEMATIC POSITION OF THE SPECIES'. 



The species of Whittleseya from Nova Scotia and New Bruns- 

 wick are closely allied to the southern representatives of the same 

 genus. The Whittleseya desiderata has the aspect ot a diminutive 

 W. elegans Newb., an example of which, from the type bed and 

 vicinity, is, for comparison, shown in PI. VII, Fig. 5. In the 

 small species the teeth are less acute, while the bands are more 

 confluent, more carinate, and less ribbon-like than in the Ohio 

 plant. In respect to the nervation, the former species agrees per- 

 haps more nearly with the material from the roof of the Sewanee 

 coal of Tennessee placed by Lesquereux in W. undulata. Tha 

 compactness of the fascicles also approaches the nervation of IV . 

 mici'ophylla (PI. vii. Fig. 7.) In fact, the longer Riversdale 

 species appears, while ranging most closely to W. elegans and 

 W. undulata^ to stand on the side toward the cuneate W. fnic7-o- 

 ptiylla. 



The Whittleseya brevifolia, though nearest to W. desiderata, 

 suggests by both its form and nervation a position between Ihe 

 latter and the W. micropliylla, an example of which, from the Type 

 locality,^ is illustrated in Fig 7. 



Whittleseya Da^vsoniana, on the other hand, is by far most 

 closely bound to W. elegatis, from the Sharon coal (Upper Potts- 

 ville) of Ohio, though its proportionately broader ribs and less 



^ Near Fayetteville, Arkansas, in the "coal bearings sliale," a formation 

 representing: a part of the Upper Pottsville, not far from the Sharon coal, in 

 the Appalachian trougfh. The species is also present in the Breathitt forma- 

 tion of Kentucky, and the Upper L^-kens division of the Pottsville in the 

 Pennsylvania Anthracite retfion.
