leading types of structure which may be recognized amongst the Palaeozoic 

 Corals. The difficulty of determining the limits of a genus or species 

 in a group of animals which exhibit so many variations as the corals 

 has decided the authors to adopt the plan of selecting certain well- 

 marked types, to which names will be given. The series of carefully 

 sliced and polished specimens which the authors possess enables them 

 to undertake this method. " No type will be described which is not 

 at the same time accurately figured ; and the facts thus recorded will 

 remain unchanged, and will retain their value whatever alteration may 

 take place in our method of interpreting them." 



In the second instalment the authors describe and define the genera 

 Ampleocus and Zajphrentis. E. T. N.

Describes fossils got by Dr. E,. von Drasche from the W. coast of 

 Spitzbergen (see Geological Record for 1874, p. 108). They are of 

 mixed Permian and Carboniferous types. Gives table of Permo-Car- 

 boniferous fossils from collections by Drasche, Payer, and Hofer ; it
