With respect to the îiolniia fauna at Tomten, it is of'interest to mention 

 Brøgger's httle work on "Fossiler fra Oxna og Kletten" ^. He there 

 states that Paradoxides ( --- Hohnia) Kjerulfi was found in green shales 

 at the uppermost part of the Kletten section, and also some examples of 

 a little brachiopod, presumably an Obolus. "The small, newly discovered 

 specimens from Kletten, in spite of their slight dimensions (the smallest 

 being scarcely 2 mm long), exhibit all the characteristics, even the spine 

 on the occipital ring is seen, even though but slightly developed in the 

 print of one specimen". These small juvenile specimens of Hohiiia are 

 very interesting, and are depicted in the present work on plate VI, fig 2 — 3. 

 Brøgger further remarks in the paper referred to, that Paradoxides Kjerulfi 

 appears to approach distinctly the American form Paradoxides (Olenellus) 

 Thompsoni Hall. 



The same consideration of this form appears in Brøgger's work 

 "Paradoxides skifrene ved Krekling"-, dated 1879. In that paper, Paradoxides 

 (Olenellus) Kjerulfi is described more thoroughly than had been done by 

 Linnarsson. The fragments of the large form are regarded as remains of 

 large, adult specimens. The Arionellus form is described as A. pri- 

 maevus and Obolus sp. and Discina sp. are mentioned without further des- 

 cription. Brøgger was thus the first to point out that Llnnarssgn's 

 Paradoxides Kjerulfi is not a real Paradoxides, but belongs to Hall's 

 genus Olenellus (1862). 



This fact was also recognised by Linnarsson in his work "De 

 undre Paradoxides lagren vid Andrarum" (1883) ^, which was of great im- 

 portance with respect to the Hohnia fauna. He also describes in the 

 same paper what are known as the Greywacke shale, which he proves to 

 be of the same age as the Kjerulfi shale at Tømten. The following forms 

 are described from the Greywacke shale at Andrarum: Olenellus Kjerulfi 

 Lnrs., Arionellus primaevus Brøg., and Ellipsocephahcs Nordenskjöldi Lnrs. 

 From the contemporary beds between Simrishamn and Brantevik he 

 mentions: Metoptoma sp. (cfr. Barrandei Lnrs.) and Obolella sp. Various 

 remarks concerning the corresponding Norwegian forms are of interest 

 here. Thus Linnarsson mentions that fig. 6 in Kjerulf's work "Sparagmit- 

 fjeldet"'^ (depicted by Kjerulf as an Arionellus) appears rather to belong 

 to Ellipsocephalus Nordenskjöldi.
