148 LABYEINTHODONTIA. 



in the ' Palaeontographica,' vol. vi. pis. xxv. & xxvi. The 

 somewhat narrow contour is well shown ; and the open 

 auditory notch (Meyer, op. cit. pi. xxiv.) is very distinctly 

 displayed. Purchased, 1866. 



42751. Mass of sandstone showing the inner laminae of the bones 

 of the cranial roof, with the exception of those of the 

 muzzle. This specimen agrees in size with the preceding. 



Purchased, 1871. 



36346. The imperfect cranium of a smaller individual. The frontal 



aspect is represented by a sandstone cast, or portions of 

 the inner lamina of bone, of the cranial roof. The upper 

 portion of the premaxillee is wanting, so that the large pre- 

 maxillary vacuity is shown. Purchased, 1862. 



36344. Slab of sandstone exhibiting the palatal aspect of a cranium 

 agreeing in size with the preceding. The contour pre- 

 cisely resembles that of the larger specimen figured by 

 Meyer, op. cit. pi. xxvi. Purchased., 1862. 



36347. Slab of sandstone showing the inner lamina of the bones 

 of the cranial roof, imperfect posteriorly. This specimen 

 is rather larger than No. 36346. Purchased, 1862. 



36348. Slab of sandstone showing the upper surface of the inferior 



lamina of the bones of the anterior extremity of the 

 palate of a small individual. Purchased, 1862. 



36350. Fragment of rock showing the inner layer of the bones of 

 the posterior portion of the cranial roof. This specimen 

 indicates a small individual, and may be referable to the 

 next species. Purchased, 1862. 



36352. Mass of sandstone showing the greater portion of a mandi- 

 bular ramus. Purchased, 1862. 



30270. Slab of sandstone showing the impression of the ventral 

 surface of the median place (interclavicle) of the thoracic 

 buckler, together with a plaster cast taken from the same. 

 This specimen indicates a small individual. Its contour 

 is very similar to that of the corresponding bone of Metopo- 

 saurus figured by E. Praas in the ' Palaeontographica,' 

 vol. xxxvi. pi. xv., and less like that of C. robustus figured 

 by Quenstedt in his ' Mastodonsaurier Wurttembergs,' 

 pi. iv. fig. 1. Purchased, 185'5.
