1898-1902 No. 32.] FOSSIL FAUNAS FROM SERIES B. 17 



ID the Devonian, besides Dictyonema and related forms, some minute 

 MoHoyraptus species only are known. 



The occurrence of graptolites in this Arctic locality is in several 

 respects of much interest. First, because the age of the beds (if they 

 really belong to the other fossiliferous beds of Series B) probably 

 is very young to bear such graptolites as will be more fully 

 discussed later on. Secondly it is very interesting to meet graptolites 

 here in this relatively very little known Arctic region, showing a type 

 that is not known in the exceedingly well investigated American Continent 

 to the south. We have here no doubt a European faunal element occur- 

 ring in the Arctic. 



It seems as if graptolites are not so very scarce in the Arctic Silurian. 

 A Monogmptus form, M.convolutus var. CoppmgeriETii. was previously 

 described by ETHERIDGE in his paper on the fossils collected on the 

 expedition of Sir GEORGE NARES (Quart. Journal Geol. Soc., vol. 34, 

 p. 577, pi. 25, fig. 1). 



Occurrence: B, upper part, south of Point north of the Beauti- 

 ful Valley. B, loose in debris in "Sundene" (?). 



Echin od erma ta. 



Crinoidea. 



Fragments of stems of crinoids are found in all localities, especially 

 however from the upper part of B from the Point north of the Beauti- 

 ful Valley in Walrus Fjord. Some pieces of the rock brought from these 

 localities might be termed crinoid-limestone. 



JVLolluscoidea. 



Bryozoa. 



Cyclostomata. 



Fistuliporidae. 



Fistulipora M'Coy. 



Fistulipora sp. 



A small piece of dark limestone shows the strongly concentrically 

 wrinkled basal epitheca of a Fistulipora, in places covered by parts of the 

 upper celluliferous layer, exhibiting the oval sections of the zooecial tubes. 

 These tubes are strikingly narrow, only about 0,150,20 mm. in dia- 

 meter and the distance between them is generally equal to the width.
