[MATTHEW] REMARKABLE FORMS OF THE LITTLE RIVER GROUP 12 1 



Horizon and Locality. — From fine sandy layers in the upper part of 

 the Lower Cordaite sliale at Fern Ledges, Lancaster, N.B. Scarce. 



Nanopus ( ?) VETusTus n. sp. Plate II, Figs. 4 and 5. 



Until it is better known we temporarily refer this foot-print to 

 Nanopns, Marsh. 'The small heavy foot mark is comparable to the one 

 made by that genus, but the toes are mere lobes of the footprint, and 

 none of the prints exhibit more than three toes. 



Footmarks heavy, irregularly three lobed, the lobes taking the place 

 of claws, only three footmarks, in alternate order, known; no distinct 

 toes other than these lobes, visible. 



Size, varying, for the difEerent footmarks, from 12 x 13 to 8 x 10 

 mm. 



Stride (space between the foot-marks), 25 mm. 



Straddle (transverse distance between the rows of footmarks), 

 15 mm. 



Horizon and Locality. — From gray sandy shales of Lower Cordaite 

 (upper sub-fauna) at Fern Ledges, Lancaster, N.B. Scarce. 



BIPEZIA n. gen. 

 This form differs from any we have seen described. The peculiar 

 double-lanceolate, two lobed imprint, is diflScult of interpretation, but 

 the nature of the track seems to indicate some form of vertebrate animal. 

 No claws or toes appear beside the anterior one to each footmark. 



BiPEZiA BiLOBATA u. sp. Plate IV, Figs. 1 and 2. 



Footprints spindle-shaped, pointed at both ends, usually in pairs 

 opposite each other and coalescing laterally, sometimes the anterior 

 sometimes the posterior part of the footmark is most distinctly impress, 

 but both the anterior and posterior ends are sharply lanceolate. Some 

 prints are shorter and rounder as though the animal pressed only the 

 point of its toe into the sand. The feet made a deep impression where 

 the shale was soft, hence the animal was heavy, or progressed by leaping. 



Size. — Length, 10 mm. Width, 3 mm. 



Stride (where the animal moved by leaps or bounds), 15 mm. 



Straddle none where the two footprints were close together; else- 

 where, about 5 mm. 



Horizon and Locality. — From a fine sandy shale of the Lower Cor- 

 daite shales (upper part) at Fern Ledges, Lancaster, N.B. 



The footprints of Batrachians observed at Murphy's Point, Little 

 Eiver, were larger than any of those above described, but have not been 

 studied or closely observed. They are in consecutive series of a number 

 of footprints on a slab of sandstone.
