[MATTHEW] REMARKABLE FORMS OF THE LITTLE RIVER GROUP 1 19- 



The externomedian (median) appears to have thrown off on its 

 upper side a weak branch which forks about the mid-length of the part 

 preserved; one branch connects with the scapular, the other extends on- 

 ward toward the end of the wing. The main trunk of the externo- 

 median vein, throws off two branches near the base of the wing which 

 are connected by an oblique branch near the middle of their length (as 

 preserved in this specimen), and beyond this the upper branch forks, the 

 one branch going toward the end of the wing, the other turning down- 

 ward and running parallel to the main branch of this vein. 



A portion of the internomedian vein (cubitus) is preserved and 

 shows two main trunks, both of which fork about the mid-length of the 

 part of the wing preserved. 



A good many nervules connecting the main veins in this wing are 

 preserved ; those between the mediastinal and scapular veins are frequent, 

 and turned diagonally backward toward the mediastinal. Other more 

 direct nervules are seen between the various branches of the median 

 veins. 



A peculiarity about this wing is the weak branch (of the externo- 

 median?) running between that vein and the scapular and connecting at 

 one point with the latter. The stone is flaked where this branch ap- 

 proaches the externomedian, near its base, and the actual contact is not 

 seen. 



Length of the part preserved, 50 mm. Width, 28 mm. The actual 

 length was probably at least a third greater, and the width also a third 

 greater than the width of the part of the wing preserved. 



Horizon and Locality. — Lower Cordaite shales at Fern Ledges, Lan- 

 caster, N.B. 



The nervation in this wing differs so widely from that of ^dœo- 

 phasma Acadica that it can hardly be of the same genus. 



FOOTPEINTS OF ANIMALS. 

 Batrachian footprints. 



For some years the author has known of the occurrence of foot- 

 prints on the plant bearing strata of the Little Eiver group, but where 

 they were seen in situ they were usually in positions on the surface of 

 hard sandstone beds where they could not easily be detached; those de- 

 scribed in the following pages have been noticed on slabs or fragments 

 of shale preserved for their plant remains; they are chiefly from beds 

 at the Fern Ledges. As these footprints were accidental discoveries on 

 small pieces of slate or shale, they are quite fragmentary and are not in 

 long connected series of footprints, such as those described from the 

 Lower Carboniferous, Coal-measures and other later terranes. But while
