11959. Cast of one of the large anterior tusk-like teeth. The 

 original, which is the type of the genus, was obtained from 

 the Alum-shales at the base of the Lettenkohle (Lowest

 described and figured by Jaeger in his ' Poss. Kept. 

 "Wiirttemberg,' p. 35, pi. iv. fig. 4 ; and is preserved in

R. 84. The base of a somewhat smaller tooth ; from the bone-bed 



at the base of the Lettenkohle at Gaildorf. This specimen 



has been cut and polished to exhibit the labyrinthic 



structure. 



Transferred from the Museum of Practical Geology, 1888. 



43637. A smaller tooth ; from the Lettenkohle of Gaildorf. The 

 summit is wanting. Purchased, 1859. 



33091. A still smaller imperfect tooth, in matrix, from the bone-bed 



of the Lettehkohle of Gaildorf. Purchased, 1848.

 and figured by Meyer and Plieninger in their * Beitrag. 

 Pal. Wiirttembergs,' p. 64, pi. vi. fig. 1, and pi. vii. fig. 1 ;

 pi. 32, pis. i. and ii. Purchased, 1877. 



33092. The imperfect centrum of a dorsal vertebra, in a somewhat 



crushed condition ; from the Lettenkohle of Gaildorf. 

 This specimen resembles the vertebrae figured by Meyer an 

 Pleininger, op. cit. pi. iv. ; of which the characters are 

 noticed by E. Praas in the ' Palaeontographica,' vol. xxxvi.

 Trias, ranting with the Keuper and Muschelkalk.
