Reiieios — Lundgreri's Cretaceous Brachiopoda. 229- 



are incoherent calcareous sandstones with a variable quantity of green 

 grains, whence it is sometimes called a greensand. Subordinate beds 

 of conglomerate, mostly of Silurian slates, are pi-esent ; but flints are 

 absent. In addition to the same divisions which, as at Kristianstad, 

 are characterized by A. subventricosus and B. mucronata. there are 

 two others beneath them ; one containing Actinocamax quadrotus, and 

 the other A. verus. Borings carried to a depth of 1300 feet have not 

 penetrated through the chalk in this district. 



The rocks of the easterly district of Malmo resemble those of 

 Denmark, and may be regarded as their easterly continuation. The 

 beds are of pure white chalk of varying degrees of hardness, and 

 layers and nodules of flint are abundant in it. The flints are black 

 or greyish, but never speckled. The general appearance of the 

 chalk in this district, as the writer can testify, resembles very closely 

 the chalk at Norwich. The Malmo chalk exceeds 600 feet in thick- 

 ness, and though its petrographic characters are so strikingly different 

 from those of the other districts, the presence in it of the same 

 typical fossil, Belemnitella mucronata, shows that it, and the Gruskalk, 

 and sandstones of the other districts, all belong to the same geological 

 horizon of the Skrifkrita, or our Upper Chalk with flints. 



In the Malmo district the Skrifkrita or Upper Chalk is overlaid 

 by higher beds, of the Etage Danien or " Newer Chalk," of which 

 three different varieties are described by Prof. Lundgren, who, how- 

 ever, regards them as merely different aspects of the same contem- 

 poraneous deposit. The first of these, the Faxoe or coral limestone, 

 is composed largely of corals which appear to have grown m situ ; it 

 also contains Crustacea [Dromia) and Gasteropods. Flints are not 

 present in it. The second is the Limsten or polyzoa-limestone, con- 

 sisting of entire and fragmentary polyzoa, corals, and other organic 

 remains, which have been rolled and rearranged by currents. It 

 also contains flints. The third variety, Saltholm limestone, is a more 

 or less compact limestone with beds of flint ; it is distinguished by- 

 its Fishes, Crustacea (Glyphea), and the so-called Ophiomorpha. 



In all these different varieties of the Danien or Newer Chalk 

 Belemnitella mucronata^ and other forms of Belemnites are absent ; but 

 they all contain two characteristic fossils, Ananchytes sulcata and 

 Terehratula lens, which are respectively very closely allied to A. 

 ovata and T. carnea of the Upper Chalk. Lundgren does not think 

 that the correspondence of these Danien beds with the Maestricht 

 Chalk has been satisfactorily proved, since in the latter B. mucronata 

 is present, and the genera and species of corals are also different ; 

 and he is disposed to accept the suggestion of Schlxiter, that they are 

 rather the equivalents of the most recent Cretaceous beds of West- 

 phalia, in which fishes and plants are present, but no Belemnites. 



Of the Brachiopoda from the Upper Chalk, only a single new 

 species, a Liugula, has been described, but there are 16 new forms 

 from the other horizons. The most prolific brachiopod fauna is in 



1 Lyell has stated that this species occurs in the Faxoe limestone, but the author 

 affirms that it certainly does not occur in this deposit, though it may be found in beds 

 of becondary, i.e. of Glacial origin which overlie it.
