380 Renens — Dr. J". W. Gregory's Fossil Bri/ozoa. 



September 7 to 11 : Secondary and Tertiary formations of the BasseS-"' 



Alpes (Dir., M. E. Haug). 

 August 11 to 14 : Turonien of Touraine and Cenomanien of the 



Mans (Dir., M. de Grossouvre). 

 Under the heading 'Excursions generales' are (1) three large 

 excursions, viz. : — 

 August 29 to September 7 : Coal-basins of Central France 



(Directors, MM. Fayol and Grand'Eury). 

 August 30 to September 8 ; Primary and Secondary formations of 



the Boulonnais and Normandy (Directors, MM. Gosselet, 



Munier-Chalmas, Pellat, Eigaux, Bigot, and Cayeux). 

 August 29 to September 15 : Central Massif of France (Directors,. 



MM. Michel Levy, Marcellin Boule, G. Fabre, and E. aI, 



Martel). '.' 



(2) Short excursions which will enable members to visit, during 

 the Congress, the Tertiary fossiliferous formations of the neighbour-- 

 hood of Paris. 



From the dates given above it will be seen that the excursions 

 take place before, during, and after the Congress. The directors 

 of the excursions are the authors of the respective notices on the 

 same, which are issued in twenty-three separate fascicules for th^ 

 convenience of the excursionists. "' 



In connection with the above it may be mentioned that at the last; 

 meeting of the Geological Society of London on June 20, a letter 

 was read from Professor Gaudry, the President of the Organizing' 

 •Committee of the Congress, to the Foreign Secretary of the" 

 Geological Society, conveying a very warm' and cordial invitation 

 to the Fellows of the Geological Society to attend the Congress, and; 

 assuring to them a hearty welcome from their geological brethren of- 

 France. It is to be hoped that this generous invitation will find 

 a ready response from our British Geologists.

FOUK years ago we had the pleasure of noting (Geol. Mag., 

 1896, p. 378) the first of what it was hoped might be a series, 

 of Catalogues of the Fossil Bryozoa in the national collection. That 

 volume, also by Dr. Gregory, dealt with the Jurassic forms, which it 

 was seen would supply the key to those that came after. Now we 

 have before us the first instalment of the Cretaceous Bryozoa. The 

 work is on the same lines as its predecessor, with such changes la 

 nomenclature (e.g. Diastoporidfe for Tubuliporidae) as experience has 

 shown to be necessarj', and is severely technical, consisting as it 

 does of descriptions of the species, with discussions as to synonymyy, 

 and so on. The general introduction to the Cretaceous Bryozoa, 

 with other interesting questions, such as lists of localities with their
