deposits worked up with care. It will be useless to raake com- 

 parisons with the deposits of Victoria or New South Wales 

 without the co-operation of the naturalists and geologists of 

 Australia generally. 



This might be most effectually brought about by appeals to 

 the parlous learned societies in Australia and New Zealand to 

 make exchanges with us and to send catalogues of their classi- 

 fied fossils, with descriptions of habitat and distribution. 



For this object I have arranged the marine fossils at Table 

 Cape into a tabular form, which not only shows at a glance 

 the distribution, so far as known, throughout the Australian 

 deposits, but also, by signs, is made to show the relative 

 abundance of each particular organism. Were the various 

 learned societies to aid in classifying their fossils in a similar 

 way, we would then be able to dispel all doubts with regard to 

 the present classification. Co-operation, therefore, is at the 

 present time of the utmost necessity, and I trust that the 

 members of the Eoyal Society of Tasmania will take the 

 initiative in a work so desirable and of such importance. 



Note. — In the table tlie following signs are tused : — + Not yet described, 

 or being examined for description by the^ Rev. J. E. Tenison-Woods. 

 c, common ; b, abundant ; c, very abundant ; u; not uncommon ; y, rare ; 

 s, vei-y rare ; /, still living.
