 three ])lates wliieh Felder himself calls " [)rovisional " in 

 August 1869 were i)ublished in 1868. So far as can be 

 ascertained from London publishers, the part containing these 

 plates is actually not to be had at the present time, and lepi- 

 dopterists are beginning to doubt whether it will ever appear 

 at all. When these things are considered, what must of 

 necessity be the feeling with regard to the second part of the 

 same work, of which British Icpidoptcrists at least saw nothing 

 until 1867, but whieli bears the date 1865?

Notes on Australian Freshwater Tortoises. 

 By Dr. J, E. Gray, F.R.S. &c. 



TiiK British Museum has received a scries of freshwater tortoises 

 belouginjif to the family Hydraspida;, from Mr. Krcfft. They are 

 preserved in spirit, and were obtained from Burnett's lliver. 



Chelymys macquaria. 



There are six specimens, of different ages, which I believe belong 

 to this species, in the collection. They aU agree in having a lead- 

 coloured head, with a broad white streak from the middle of the 

 hinder part of the orbit to the upper front margin of the tympanum, 

 and a similar rather broad streak from the angle of the mouth to the 

 underside of the tympanum. 



In general the gullet and throat below this line are white, but in 

 some they are more or less varied with lead-colour. The thorax in all 

 the specimens is much more oblong and convex than in the specimens 

 received from Scgou, in the Macquarie River ; but they vary both 

 in the outline of the thorax and in the convexity of the back very 

 considerably. The smallest is the broadest, with the back of the 

 shell much elevated in the centre. Indeed no two of the specimens 

 are alike in fonn and convexity, which induces me to believe that 

 they all belong to one very variable species.
