168 CHELONIA. 



Genus CHELODINA, Pitzinger \ 



Por the characters of this genus see Boulenger, 'Catalogue of 

 Chelonians,' &c. p. 213. It may be remarked that neural bones are 

 absent, and that the outer surface of the shell is more or less distinctly 

 vermiculated ; a neural shield being always present. 



Cfjelotftna longtcollfe (Shaw 2 ). 

 Syn. Testudo longicollis, Shaw 3 . 



In this, the type, species the shell is thick, with the vermicula- 

 tions strongly marked, and the sulci dividing the epidermal shields 

 very deeply impressed ; the nuchal shield is long and narrow. 



Hob. Australia (southern half). 



48473. An imperfect nuchal bone ; from the Pleistocene of West- 

 brook, a tributary of Oakey Creek, which runs into the 

 Condamine river, Queensland. This specimen cannot be 

 distinguished from the nuchal bone of the existing form, 

 showing the same long and narrow nuchal shield; it may, 

 however, be referable to C. eocpansa, which has a similar 

 nuchal shield. Presented by Dr. George Bennett. 



R. 616. The tenth marginal bone of the right side, belonging either 

 to the present or a closely allied form ; from the Pleisto- 

 cene of Eton Yale, Darling Downs, South Queensland. 

 This specimen shows the sulcus dividing two marginal 

 shields, and also the sulci dividing these marginals from 

 the last costal and fifth vertebral shields. 



Presented by Dr. George Bennett, 1885. 



R. 617. A small right humerus which may belong to the present or 

 an allied form ; from the Pleistocene of Eton Yale. 



Presented by Dr. George Bennett, 1885. 



Genus EMYDURA, Bonaparte 4 . 



Por the characters of this genus see Boulenger, ' Catalogue of 

 Chelonians,' &c. p. 228. It may be observed that the shell is usually 

 more or less distinctly vermiculated, but that the sulci marking the
