Summary. 



The tield-work of the present essay on »The extent of the Asaphus Region in 

 S. E. Scania and in Bornhohn» has been carried out with longer or shorter inter- 

 ruptions during the summers of 1915—1919. The places which have been the 

 special object of my researches are Komstad, Tommarp, Tosterup, and Bollerup in 

 S. E. Scania, and Vasagaard and Hullegaard in Bornhohn. 



At Komstad I have demonstrated the zone of Phyllograptus angustifolkis Hall 

 a little north of tlie large limestone quarry. I have also found here the zone of 

 Isograpfus gibherulus Nich. In the Orthoceras limestone, Megalaspis limhata Sars 

 & BoEOK occurs right down in the lowest banks. Megalaspis planilimbata Ang. 

 could not be found, in spite of careful examination, so that Planilimbata limestone 

 must be excluded from the series of strata in question. 



At Tommarp the zone of Isograptus gibherulus Nich. is probably to be found 

 above the zone of Phyllogr. angusiifolius Hall, although it could not be demon- 

 strated on account of the thickness of the Quaternary deposits. The Orthoceras lime- 

 stone is composed of Limbata limestone and Lower Asaphus limestone. The last- 

 named zone has been established by my discovery of Plychopyge applanata Ang., 

 Megalaspis ocuticauda Ang., and Cyrlometopus clatifrons Dalm. in the upper portion 

 of the Orthoceras limestone. In Mobeeg'ö locality T 3 ' is to be found the zone of 

 TrinucUus coscinorrhinus Ang., with underlying conglomerate and transitional layers. 

 33 metres north of T 3 I dug a well 6,6 m. deep, in which I studied the strata from 

 the lower portion of the Clingani shale down to the Coscinorrhinus-zone. The beds 

 between the Clingani-shale and the Orthoceras limestone are the following (for every 

 fossil-bearing stratum the reader is referred to a column in the paleontological 

 synopsis, pp. 38 and 39, in which every fossil occurring in the stratum is denoted 

 by +): 



Clingani-shale (column 7). 



Cystidean shale: — Dark grey shale, calcareous underneath, with nu- 

 merous cystidea above (column 6) 0.60 m.
