in that it is as high as broad. The length is 43 mm. and the lower 

 border is moderately concave. The dimensions make it possible that 

 it belongs to the same species as the other specimen. The articular 

 surfaces for the arch are beautifully displayed. There is a fragment 

 of an arch showing a transverse process with a very concave under 

 surface and incomplete neck and caudal vertebrae together with 

 fragments of ribs.

The following details of the type specimen are taken from von 

 Huene's account, checked by examination of casts of the type which 

 are in the South African Museum. 



The cervical vertebrae are elongate, with a keeled under surface 

 as in Plateosaurtts. The zygapophyses are long anteriorly, and 

 posteriorly are elongate with oblique articular surfaces. The neural 

 spine is short, low, and thin. 



The centrum of the 1st dorsal vertebra is characterised by the 

 extraordinarily high thin keel on the ventral surface. A few of the 

 other dorsal vertebrae are known. They are compressed in the 

 middle and the ventral side is rounded. 



The anterior caudals are very short and high, and broadly rounded 

 below. The later ones are provided with a keel below and earn- 

 posteriorly a ventral groove, which divides partially the face for the 

 articulation of the haemapophysis. The middle and hinder caudals 

 are longer, but do not reach the length of the cervicals. 



The scapula is small and slender and is characterised by a high 

 alar process at the distal end on the upper side; the coracoidal half 

 of this process is thin and concave from without, as in Plateosaurus, 

 but more strongly so; the medial side of the process is flat. The 

 distal end is broadened. 



In the humerus the proximal end is broad, the upper border 

 obliquely bent down to the processus lateralis which is sharply cut
