110 Canadian Record of Science. 



Sir Wm. Dawson's description states that there were 

 five toes to the hind foot, and four to the forefoot, with a 

 doubtful fifth toe. 



The figure of this species, which is a rough presentation 

 of its form, will be found in Geol. Magazine, London, Series 

 1, vol. ix. p. 251-253. 



The generic name is in allusion to remarkable grasping 

 power possessed by the foot in which it resembled the 

 sloths. 



Description of the Plate. 



Fig. 1. Baropezia — Type Sauropus Sydnensis, Dawson 

 — a. Mould of the right hind foot — b. Mould of the right 

 forefoot. Both natural size. The figures show the relative 

 positions of the hind and forefoot. From Coal Measures, 

 Sydney, N.S. See p. 105. 



Fig. 2. Megapezia — Type Megapezia Pineoi, n. sp. — a. 

 The left hindfoot — b. The left forefoot. Both natural size. 

 (Mud has flowed into the footprints so as to narrow them 

 in places and blunt the ends of the toes.) The forefoot in 

 a series of footmarks is not so near the hind as here repre- 

 sented, they are crowded on the plate to save space-

Fig. 3. Asperipes — Type Asperipes avipes, n. sp. — a. 

 Mould of left hindfoot — b. Mould of left forefoot. Both 

 natural size. The figures are in their natural position. 

 From Coal Measures, Joggins, N.S. See p. 101. 



Fig, 4. Cursipes — Type Cursipes Dawsoni, n. sp. — a. 

 Left hindfoot — b. Left forefoot. The footprints are in 

 their natural position ; the line of the series of footprints 

 if prolonged backward would pass between the two larger 

 figures at the bottom of the plate. From Coal Measures, 

 Joggins, N.S. See p. 103. 



Fig. 5. Barillopus — Type Baropus unguifer, Matt. — 

 a. Left hindfoot — b. Left forefoot. Both mag. -f. The 

 forefoot in its natural position is close behind or partly
