TAPINOCEPHALIDiE. 87 



43525 h. An imperfect associated lumbar vertebra ; from Gats- 

 (Fig.) Plaatz. Figured by Owen, he. cit., pi. iv. The con- 

 tour of the centrum is almost identical with that of the 

 vertebra No. E. 1706 ; but the present specimen is of 

 somewhat smaller size, a difference which may be merely 

 an individual character. There is the same notch between 

 the arch and the centrum as in No. E. 1706. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



43525 i. An imperfect sacrum, associated with the preceding ; from 

 (Fig.) Gats-Plaatz. Figured by Owen, op. eit. pi. v. Pour 

 vertebrae remain : but there is no evidence to show that 

 the 3rd and 4th are not anterior caudals, and that the true 

 sacrals were more than two in number. In the angulated 

 contour of the centrum the first sacral accords with the 

 lumbar. The 3rd and 4th vertebrae have notches at the 

 junction of the arch with the centrum, as in the lumbars.

43525 k. The imperfect centrum of an associated anterior caudal 

 vertebra ; from Gats-Plaatz. Noticed by Owen, op. cit. 

 p. 5, as No. 11. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



43525 1. The imperfect centrum of an associated later caudal ver- 

 (Fig.) tebra, which has been bisected to exhibit the notochordal 



canal ; from Gats-Plaatz. Figured by Owen, op. cit. pi. v. 



fig. 4. Presented by W. G. Atherstone, Esq., M.D., 1872. 



43525 j. The imperfect proximal portion of a dorsal rib, associated 

 with the preceding specimens ; from Gats-Plaatz. Noticed 

 by Owen, op. cit. p. 5, No. 12. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



43525 x. An imperfect late caudal vertebra apparently belonging 

 to this series. This specimen is labelled " Jan Willem's 

 Farm," but it is indistinguishable in mineral characters 

 from the preceding.
