other alveoli for single-rooted teeth ; these occupy the anterior 

 26 centimetres of the jaw. The next tooth is in situ ; its anterior 

 border is 32 cm. from the tip of the jaw. The crown is high 

 and conical, somewhat compressed from side to side, with sharp 

 anterior and posterior edges and slightly curved backwards. On 

 the anterior edge near the base of the tooth there are five or six 

 blunt, upwardly directed denticulations, while on the posterior 

 edge there are four or five larger ones. The height of the tooth 

 crown was 6'o cm., the length of its base 5 cm. The next tooth, 

 separated from the last by an interval of about 5 cm., was broad 

 and double-rooted ; its crown is somewhat broken, but it can be 

 seen that on its anterior and posterior edges there were several 

 large and sharp denticulations. The length of the tooth at its base 

 was about 6-6 cm. The next tooth, which is separated from the 

 last by an interval of 45 cm., is similar, as also is the next, which 

 is in contact with that in front. The last three teeth (the molars) 

 differ considerably from those just described. They are closely 

 crowded, and have a nearly straight anterior border, denticulations 

 occurring on their posterior edge only. On the whole the dentition 

 closely resembles that of Zeiiglodon osiris as figured by Stromer.^ 



A number of very large vertebrse have also been found ; the 

 dimensions of one of these are : — Length of centrum, 23*5 cm. ; 

 transverse diameter, 17'7cm. ; vertical diameter, 15 cm. 



P.S. — In reference to my account of the teeth of Arsinoitlierium 

 given in the last part of these notes, my attention has been drawn 

 to the fact that in a footnote to one of his geological papers 

 Blanckenhorn has mentioned the similarity between this dentition 

 and that of Coryphodon.

rpHE following Eeport of the Palaeontologist of the National 

 _L Museum, Melbourne, Mr. Frederick Chapman, has recently 

 been issued, and gives a good general idea of the material available 

 for study in that Institution : — 



After the preliminary work of unpacking and generally inspecting 

 the collections of fossils placed in my charge, the work of selecting 

 a series of specimens to illustrate Australian, and particularly 

 Victorian, palasontology was commenced. This has been pro- 

 gressing, in conjunction with other necessary work, with the result 

 that there are now on view 15 table-cases of typical Australian 

 fossils, including the Cambrian, Ordovician (Lower and Upper), and 

 the Silurian. 1 have introduced certain noteworthy features, such 

 as explanatory diagrams and illustrations, into the arrangement of 

 these cases, in order to make them more interesting, both to students
