all other respects the resemblance between the vertebrae of the two 

 genera is extremely close. 



The so-called Palceopython is founded upon specimens which 

 cannot be distinguished from the vertebrae of the type species of 

 Paleryx ; see ' Geol. Mag.' dec. 3, vol. v, p. 112 (1888). 



Paleryx rhombifer, Owen 1 . 



Syn. (?) Python oadurcensis, Filhol 2 . 



Paleeopython cadurcensis, Rochebrune 3 . 



The type species. Typically four or five feet in length, but, if 

 Python cadurcensis be identical, reaching to a considerably larger 

 size. The vertebra figured by Eochebrune as Palceopython cadur- 

 censis cannot be distinguished from the type vertebra of the present 

 species, and is probably identical with Python cadurcensis ; but if 

 not, must be taken as the type of Palceojpython. 



Hob. Europe (England and France). 



25259. An anterior trunk vertebra ; from the Upper Eocene (Lower 



{Fig.) Oligocene) of Hordwell, Hampshire. The type specimen ; 



figured by Owen in his 'Reptilia of the London Clay,' 



pt. 3, pi. xiii. figs. 29-32. Noticed in the < Geol. Mag.' 



loc. cit. Presented by S. V. Wood, Esq., 1850. 



32837. A series of vertebrae, of which at least a considerable number 

 belong to the present species ; from Hordwell. 



Hastings Collection. Purchased, 1855. 



32837 a. Nine associated trunk vertebrae belonging to a small indi- 

 vidual of the present or to a closely allied form ; from 

 Hordwell. Same history, 



32839. A trunk vertebra in matrix ; from Hordwell. Same history. 



R. 428. An anterior trunk vertebra ; from the Phosphorites (Upper 

 Eocene=Lower Oligocene) of Caylux (Tarn- et- Garonne), 

 France. Purchased, 1885. 



R. 428 a. Three trunk vertebrae ; from the Phosphorites of Caylux. 



(Fig.) These vertebrae (fig. 55) cannot be specifically distinguished 

 from the type (No. 25259), and also agree exactly with 

 the one figured by Eochebrune in the ' Nouv. Archiv. d. 

 Museum/ ser. 2, vol. iii. pi. xix. figs. 4, a, b, c, under the 

 name of Palceojpython cadurcensis. Noticed in the ' Geol. 

 Mag.' loc. cit. Same history.
