216 SAUKOPTEKYGTA. 



R. 827. A mass of matrix containing three imperfect anterior 

 cervical vertebrae ; from the Cretaceous of Amuri Bluff, 

 North Island, New Zealand. Allowing for the absence 

 of the ribs and the abrasion of the haemal carina, these 

 specimens accord very closely with the cervicals of O. 

 constrictus in the skeleton No. 47295 marked 7 and 14. 



By exchange with the Wellington Museum, 1880. 



R. 827 a. An imperfect centrum of what is apparently a late cervical 

 vertebra, in matrix ; associated with the preceding. 



By exchange with the Wellington Museum, 1880. 



R. 827 b. Mass of rock containing the broken centrum of a 

 (?) " pectoral " vertebra and a carpal bone ; associated 

 with the preceding. 



By exchange with the Wellington Museum, 1880. 



47344. Cast of a restored dorsal vertebra. The original, which 

 wants the neural spine and the left transverse process, 

 was obtained from Amuri Bluff, and is one of the types. 

 It is preserved in the Museum at Wellington, and is 

 figured by Hector in the ' Trans. N. Zealand Inst.' vol. vi. 

 pi. xxix. It closely resembles the dorsal of the type of 

 Elasmosaurus jplatyurus, figured by Cope, op. cit. pi. ii., 

 although in that figure the neural spine is made much too 

 tall. The dimensions of the centrum are : — length 0,112 

 (4-4 inches), height 0,132 (5-2 inches), width 0,137 (5-4 

 inches). The very prominent haemal carina is apparently 

 an incorrect restoration. 

 Presented by the Director of the Wellington Museum, 1876. 



R. 829. Two imperfect associated trunk vertebrae apparently 

 belonging to the anterior dorsal region; from Amuri 

 Bluff. There is a deep lateral depression on the side of 

 the centrum immediately below the arch, of which there 

 is only a trace in the vertebra marked 34 in the above- 

 mentioned skeleton of C. constrictus : this feature may be 

 a specific character. The terminal faces have a distinct 

 central mammilla, which is faintly indicated in the 

 European species. 



By exchange ivith the Wellington Museum, 1880. 



R. 829 a. A smaller imperfect vertebra ; from Amuri Bluff. 



By exchange with the Wellington Museum, 1880.
