bed of " Upper Astartian" of Crozot (pp. 15-32). This contains a list 

 of 115 species of fossils, with their range and some remarks, including a 

 description of the following new species : — Tornatella suhmyosotis, Lima 

 Heimi, and Amorjphosjyonyia Crozotensis. W. W.

 faite le 16 Juillet 1874 an Bolderberg pres de Hasselt. [Excursion 

 to the Bolderberg.] Proc.-verb. Soc. Mai. Belg. t. iii. pp. clxxv- 

 clxxxiv. 



The Bolderberg hill is formed of the following beds, in ascending 

 order : — Rupelian Clay (Middle Oligocene) ; Bolderian of Dumont ; 

 Diestian sands (Pliocene), — the entire hill standing as an island in a 

 sea of Campinian sand (Quaternary). The author shows that the Bol- 

 derian is not a separate system, but an upper littoral member of the 

 Bupelian series. The Diestian sands lie upon a denuded surface of the 

 Bolderian ; and this break represents the Miocene continental era in 

 Belgiufn. G. A. L.

 From an examination of fossils from these borings the Eeporter con- 

 cludes that in that district the Middle Eocene is chiefly represented by 

 its upper part or Laekenian system. G. A. L.
