4. — The particular form which appears to be in the direct line of 

 descent, and which is of Australian occurrence, is the well-known 

 European type, ** Rhynchonella " variabilis, Schlotheim, sp. 



.5. — The majority of form of Tegulorhynchia point to the fact that they 

 were mainly inhabitants of shallow to moderately deep water, 

 probably ranging from shore-line to several hundred fathoms. 



6. — Twelve species are here arranged under the genus TegulorhyncMa, 

 of which two are new, namely, T. coelospina and T. thomsoni. 



7. — Our present knowledge of the distribution of the genus, both living 

 and fossil, includes Patagonia, Brazil, Antarctica, Kerguelen Island, 

 New Zealand, Victoria, Tasmania and South- Australia. 



8. — The doubtful record, as an Australian fossil, of " Rhynchonella 

 haileyana " has been examined in the light of the figured specimen, 

 and it is here definitely referred to the European species, Cyclo- 

 thyris limbata, Schlotheim, sp.
