ELEPHAS MERIDIONALIS.— TARSUS. 227 



The external calcaneal facet is 4*5x4, and the internal 4*8x4 inches; the navicular 

 is 6*4 in breadth, by 3*4 inches in height. 



The left astragal, No. 33,425, B. M., from the Forest Bed, Happisborough 

 (PI. XIX, fig. 6) has the posterior angle almost obsolete, the same being usually 

 pronounced in the Mammoth and Asiatic. The dimensions of the above are — 

 Length 7*5 inches. 

 Width 8*4 inches. 



Tibial (a. p. d.) 6*4 by C*4 inches (width). 

 Navicular facet 3*8 (height) by 7*8 inches (width). 

 Calcaneal facet (outer) 5 (a. p. d.) by 4 inches (width). 



„ „ (inner) 4*8 by 3 inches. 



Here, as in the preceding, the interosseous pit between the calcaneal facets is narrow 

 in comparison with the Mammoth and Asiatic, and runs along the entire base. 



The absence of pronounced angles and the usual concavities and convexities in the 

 nicely interlocked bones of the recent wild animals, and the majority of the same in the 

 Mammoth, may be another indication of the tardy movements of the colossal denizens of 

 the Pre-glacial forests of East Anglia. 



Calcaneum. — One of the largest heel-bones I have seen is in the possession of Mr. 

 Randall Johnson, of Palling, near Stalham. The specimen was obtained at Horge, in 

 the so-called " Norwich Crag." Its dimensions are — 

 Length 10 inches. 1 

 Width 8 



Outer astragal facet 5*2X2*2 inches. 

 Inner „ ,, 5*3x2 inches. 

 Cuboidal facet 4x 2*4 inches in height. 



The girth behind the articulations, or neck of heel, is 14*5 inches. 

 The tibial facet (by tape) is 4*4 inches. 



The National Collection contains two huge calcanea from Happisborough (Nos. 

 33,420 and 33,425) ; the former is somewhat injured, but preserves the following 

 measurements : 2 



Length 9*8 inches. 



Height 7*5 „ 



External astragal facet 3*8 (a. p. d.) by 3'4 inches. 



Internal „ „ 4*5 „ 



Cuboidal 3 (height) by 5 inches (width). 



Fibular facet 4*8 (a. p. d.) by 2 inches (height). 



None of the articular surfaces in these two bones present the concavities so 



1 This dimension is exceeded by one recorded by Nesti from Val d'Arno, which was 0'295 m. = ll # 6 

 inches in length.
