The whole of the pes except the tarsal elements is known in 

 perfect condition, though probably the metatarsals are slightly 

 crushed proximally. 



The 1st metatarsal is 87 mm. in length, the proximal end is 

 40 mm., and the distal end 36 mm. wide. The upper end fits into 

 a deep concavity on the inner side of the 2nd metatarsal. 



The 2nd metatarsal has the proximal end irregularly quadrangular, 

 with the one diagonal considerably longer than the other. The 

 greatest width is 63 mm. The greatest length is 138 mm., and the 

 distal end measures 39 mm. across. 



The 3rd metatarsal has the proximal end irregularly triangular. 

 The greatest measurement across the upper end is 45 mm. The 

 total length of the bone is 154 mm., and the distal end measures 

 38 mm. in width. 



The 4th metatarsal has the head greatly flattened partly, per- 

 haps, increased by crushing. The greatest length of this end is 

 55 mm. The total length of the bone is 135 mm., and the width of 

 the distal end is 31 mm. 



The 5th metatarsal measures 75 mm. in length. The proximal 

 end is 44 mm. and the distal end 18 mm. across. 



On the whole there is much resemblance between the metatarsals 

 of Massospondylus harriesi and those of Teratosaurus trossingensis, 

 though the latter is about twice as large.
