4. The Australian Tertiary flora, in accordance with the pre- 

 ceding statements, is but a part of one and the same original flora 

 upon which all living floras of the globe are founded, 



5. The comparison of this original flora with the present floras of 

 the globe shows that in Australia the differentiation of the Phylones 

 reached its highest limit. 



6. Many analogies to the Tertiary flora are nevertheless to be 

 found in the living. Australian flora. 



4. " On some new Features in Pelanechiniis corallinus." By T, 

 T. Groom, Esq. (Communicated by Prof. T. M'Kenny Hughes, M.A., 

 F.G.S.) 



The discovery by the Author, in the Coral Eag at Calne, of an 

 additional and well-preserved specimen of the Echinoderm originally 

 described by Dr. Wright as a Hemipedina, but subsequently made 

 the type of a new genus, PelanecJiinus, by Mr. Walter Keeping, 

 afforded an opportunity of adding considerably to the known cha- 

 racters of the type. The test proved to be flexible, as in the Echino- 

 thuridae, a point already noted by Mr. Keeping. 



A number of details as to the interambulacral and ambulacral 

 areas, the imbricating peristomial plates, pedicellariae, and teeth 

 were given. Pedicellariae did not appear to have been previously 

 observed in fossils. 



The genus appeared to occupy an intermediate position between 

 the Echinothuridae, Echinidae, and Diadematidse, and must form the 

 type of a distinct subfamily, perhaps referable to the last named. A 

 new description of the species was added.

On the Races of the Honey-Bee. 

 By the Eev. H. W. Lett, M.A., T.C.D. 



The increase of bee-keeping, the spread of literature treating 

 exclusively of the subject, and the attention paid by bee-keepers in 

 Europe, America, Asia, and Africa to the improvement of the honey- 

 bee {Apis mellifica) have demonstrated that there are at least ten 

 distinct varieties of this insect which are kept in hives. 



And though this has occurred within the last fifteen years, no 

 notice seems to have been taken of the existence of these well- 

 marked races of the domesticated insect in its bearing on the theory 

 of evolution. That interesting chapter in the history of that 

 teaching has not yet been written ; indeed, the facts summarized 

 below are only to be found scattered over the pages of many bee- 

 publications, some of which are difiicult of access. The present 

 paper is offered as a contribution towards that part of the natural 

 history of the honey-bee. 



The following are the names and distinguishing features of each
