PLESI03AURID.3:. 221 



36074. The imperfect centra of two posterior cervical vertebrae ; 



from the Cretaceous of the South Island, New Zealand. 

 The type specimens. Described by Owen in the ' Rep. Brit. 

 Assoc' for 1861, Trans, of Sections, p. 122 ; and also by 

 Hector, in the ' Trans. N. Zealand Inst.' vol. vi. p. 338 ; 

 the horizon in the original description being described as 

 Jurassic. Dimensions : — length 0,044 (1'75 inches), 

 height 0,057 (2-25 inches), width 0,090 (3-55 inches). 

 These specimens cannot be distinguished from the cervicals 

 of the type of P. crassicostatus, figured by Owen in the 

 ' Geol. Hag.' dec. 1, vol. vii. pi. iii., and by Hector, op. cit. 

 pi. xxviii. Neither the ribs nor arch were anchylosed to 

 the centrum. The resemblance to the posterior cervicals 

 of C. planus is extremely close. 



Presented by O. T. H. Hood, Esq., 1861. 



R. 831. The centrum of an earlier cervical vertebra of similar type ; 

 from the Cretaceous of AVaipara, South Island, New 

 Zealand. By exchange with the Wellington 



Museum, 1880. 



R. 837. The centra and arches of immature dorsal vertebrae ; from 

 Waipara. The larger centrum closely resembles the 

 dorsal of C. planus No. 36153 (p. 219) but is smaller. 



By exchange with the Wellington Museum, 1880. 



37413. Slab showing a series of imperfect cervical ribs together 

 with impressions of the centra of the vertebras ; from the 

 South Island. Presented by C. T. H. Hood, Esq., 1863. 



36075. Slab showing portions of ribs ; from the South Island. 



Presented by C. T. H. Hood, Esq., 1861. 



36073. Fragment of the anterior portion of the coracoids ; from 

 the South Island. This specimen was associated with the 

 type vertebrae, and is described by Owen in the passage 

 cited. The general contour is of the general type obtaining 

 in the English Jurassic specimen No. 46833 (p. 203), but 

 there is a more gradual slope from the sides towards the 

 middle bar for connection with the scapulae. 



Presented by C. T. II. Hood, Esq., 1861. 



36073 a. Fragment of a scapula of the same individual. 



Presented by C. T. H. Hood, Esq., 1861.
