Iii the narrow isthmus between Liodden and Liøen we have 

 the continuation of these marble-zones. 



The further continuation of these layers is to be found in the 

 tract at Os about 35 kra. south of Bergen (see fig. 1). In the 

 marble-zones at Kuven and Valle, Reusch has formerly found 

 sections of gastropodes, chaincorals, cupcorats, and a coral which has 

 been designated by Reusch as Syringophyllum organum (?). From 

 the Os-tract I have during the last years gathered rathér a great 

 number of fossils, hoping by means of these to be able to deter- 

 m.ine somewbat exactly to which stage the marble-zone in question 

 belongs. Prof. Kiær, who has kindly examined my material, has 

 found that the forms, designated by dr. Reusch as Syringophyllum 

 ■organum, can hardly be syringophyllum; nor did he suppose the 

 latter to be Syringopora bifurcata, as suggested by a foreign paleon- 

 tologist who has seen the collections of our museum. He is of 

 the opinion that the forms in question may possibly belong to the 

 genus Catophyllum, occurring already in stage 5 in the Kristiania- 

 area. Romingeria shows also considerable resemblanee. However, 

 the preservation is so bad that he did not arrive at any certain 

 conclusion. He could, however, establish the fact that the chain- 

 coral found is Halysites escharoides. Neither do the gastropodes 

 permit of any certain determination, but are very likely from stage 

 5 a. All the fauna is upon the whole very like the fauna of the 

 Silurian stage 5 a. 



In the area here dealt with, fossils are found in several places 

 on the stretch Hekland — Liøen. In the dark marble at Skaftaa I 

 have found soine extremely badly preserved remnants of the corals 

 which have been designated by prof. Kiær as most likely belonging 

 to the genus Catophyllum. In the layers west of Trengereid station 

 Reusch once found in a dark marble, strongiy mixed with phyl- 

 lite in small lamels and shells, a section of a gastropod, some hollow 

 reeds, perhaps encrinite-stalks, moreover an indistinct plait 

 similar to the finemeshed chain-corals from Os. In the great chief 

 zone about 200 m. east of the school-building at Trengereid, I have 

 found strongiy obliterated specimens of Halysites escharoides as well 

 as of Catophyllum. In several places on the western shore of Lange- 

 vand I found Halysites escharoides as well as Catophyllum sp.: the 

 two localities whcre the corals could best be seen were at the high- 

 way about 110 ra. south of the bridge at Odejord and down on 

 the shore at Langevand. Near Hisdal I have fouud Halysites
