Explanation of Plates. 
Plate XVI. 
Myriodon Senekalensis Van Hoepen. 
The large mass of the remains. Three individuals are 
lying near to each other. Large portions of the ventral 
armour are still preserved. Parts of the vertebral 
columns, the hind and from legs and the shoulder girdle 
are shown in this plate. About 1 : 16 natural size. 
Plate XVII. 
The smaller slab of the remains. This slab fits on to the 
large one in such a way that the vertebral column shown 
to the left lies in front of the large tail, shown in PI. 
XVI. Attention must be drawn to the fine pieces of 
dermal armour. Near the middle a quantity of ventral 
scutes are seen to gradually pass over in round ones. 
At the extreme right a portion of the dorsal armour is 
visible. About 1:11 natural size. 
Plate XVIII. 
Lower view of the palate. The basisphenoid, the para- 
sphenoid and the greater part of the pterygoids are 
shown. In the inter-pterygoidal vacuities lies the 
mosaic of teeth bearing ossifications. 0,6 natural size. 
Plate XIX. 
Fig. 1. — Right ramus of the lower jaw, probably of skull 
No. 2, and belonging to the upper individuai of PI. 
XVI. Nearly 0,8 natural size. 
Fig. 2— Part of the vertebral column of the middle indi- 
vidual of PI. XVI. About 0,2 natural size. 
Plate XX. 
The tail of the lower individual of Plate XVI. About 1 : 3 
natural size. 
Plate XXI. 
Sternum and clavicles with complete front leg. About 1 : 3 
natural size. 
Plate XXII . 
The hind legs and pelvis of the middle individual of 
PI. XVI. About 23 : 100 natural size. 
Plate XXIII. 
A portion of the ventral armour near the sternal apparatus 
of the lower individual of Plate XVI. About 0,9 natural 
size.
