180 LABYEINTHODONTIA. 



35800-01. A split nodule showing the frontal aspect of the hinder 

 portion of the skull. The sculptured lamina remains in 

 position between the orbits. 



Presented by Sir B. Owen, K.C.B., 1861. 



42806. A split nodule exhibiting a smaller skull from the frontal 

 aspect. The two mandibular rami are displaced and shown 

 on either side of the cranium. This well-preserved speci- 

 men is rather smaller than the type skull. 



Van Breda Collection. Purchased, 1871, 



R. 1298. A split nodule showing the skull and thoracic region of an 

 immature individual. One side shows the under surface of 

 the cranial bones and the external surface of the thoracic 

 buckler and ventral scutes : while the other exhibits the 

 frontal aspect of the skull, without the external lamina, 

 and the impression of the ventral armour. The latter slab 

 also exhibits the imperfect femur and tibia of either side. 

 The length of the cranium in the middle line is 0,125, 

 and its greatest width 0,080 ; the extreme length being 

 0,160. By exchange, 1888. 



40043. A split nodule showing the skull and part of the ventral 

 armour of a rather smaller individual. Purchased, 1866. 



42754. A split nodule showing the skull, ventral armour, and the 

 impressions of the ribs and limb-bones of an individual 

 agreeing approximately in size with the preceding specimen. 

 The skull appears to be relatively wider than in the latter, 

 but this is due to the mandibular rami being flattened out 

 alongside of the maxillae. 



Van Breda Collection. Purchased, 1871. 



40004. A split nodule exhibiting the imperfect anterior portion of 

 the skeleton of an immature individual. The sclerotic 

 plates are well preserved, and faint traces of the vertebral 

 column remain. Purchased, 1866. 



35798. A split nodule with the skull and part of the ventral armour 

 of a smaller specimen. 



Presented by Sir B. Owen, K.C.B., 1861. 



33069. A nodule showing the skull of a young individual. Portions 

 of the sculptured lamina are wanting, but the specimen 

 is otherwise well preserved ; its length in the middle line 

 is 0,080. Purchased, 1848.
