confidently affirmed that " the old dogma limiting the great thrust 

 movements to a great depth stands no more". 



Professor Goldschmidt parallels the Flysch with the " Heifjelds- 

 kvarts" formation. Just as the " Heifjeldskvarts " is Caledonian, 

 so the Flysch is Alpine in age, being formed contemporaneously with 

 the mountain - building movements, though the petrographical 

 similarity between the two formations is very small, one obtaining 

 its material from forward-thrust eruptivesandthe other from forward- 

 thrust Mesozoic sediments. In the discussion following the reading 

 of the paper Professor Bregger expressed his approval of the original 

 views set forth, and the further work of the Norwegian geologists in 

 the light of the new theory will be followed with great interest.

II. — On some Cretaceous Brachiopoda and Mollusca from Angola, 

 Portuguese West Africa. By II. Bullen Newton. Trans. 

 Royal Soc. Edinburgh, vol. li, pt. iii, No. 15, August, 1916. 

 rpHE fossils described in this paper were collected by Professor 

 L J. W. Gregory and Mr. E. Robins from a cream-coloured 

 limestone in the neighbourhood of Lobito Bay, north of Benguella in 

 Angola. Most of the specimens are poorly preserved, but the author 

 considers that there is sufficient evidence to refer the fauna to the 

 Vraconnian stage, and this view receives support from the Cephalopods 

 which have been examined by Mr. G. C. Crick. Twenty species are 

 described, of which only seven are definitely identified with forms 

 already known, and two are described as new. Twelve of the species 

 are either identified or compared with European forms. The 

 ', Brazilian facies ' of the fauna mentioned by the author seems to 

 depend mainly on some resemblance between Akera Gregory i and 

 A. Browni, since the other species common to Angola and Brazil are 

 widely distributed forms. 



The species recorded by Mr. Newton are : Terebratula depressa, 

 Lam., Exogyra cf. flabellata, Goldf., Neithea ' ceqicicostata, Lam., 

 JV. angoliensis, sp.nov., N~. quadricostata, Sow., JV. tricostata, Coq.,

WHAT the Walker Museum may previously have contributed 

 seems generally unknown in this country, but if the isolated 

 part that has reached the review-office of the Geological Magazine 

 be a fair sample we should be glad to see more.
