In this respect the Greenland specimens have a stronger resem- 

 blance to Л. firma Gardner^) from the Headon Series. 



The Coeloma-bed: 1 specimen. 



The С yr en a- bed: 4 specimens. 



Occurrence: This species with its varietées is plentiful 

 in Eocene, Oligocène, and Miocene deposits in Denmark, Eng- 

 land, Belgium and Germany. 



16. Fusus sp. 



In the material from the Cyrena-bed I have found a small 

 specimen of a Fusus, but junfortunately it is too imperfect for 

 the determination of the species. It is 6 — 7 mm. long; partly 

 it presents itself in a longitudinal section, and partly it shows 

 some of the surface. The former has a small number of some- 

 what curved transverse ribs, and a great number of fine regularly 

 elevated spiral ridges. The columella seems to have been 

 without folds. 



The Cyrena-bed: 1 specimen. 



In the brown shale of the Coeloma-bed has been found a 

 gastropod, which seems to be the last whorl of a Fusus. As 

 the surface here has numerous quite fine transverse ribs, it 

 cannot be the same species as the specimen from the Cyrena-bed. 



17. Bulimulus sp.l 



Some specimens of a gastropod I determine — though 

 not without some doubt — as belonging to the genus Buli- 

 mulus Lkach. The shell is rather thick, and as it is now 

 transformed into calcite, and consequently very brittle, I have 

 only to a slight degree been able to perform any preparation. 

 The form is oblong-oval; the whorls slightly arched, and the 

 suture slightly visible. The aperture is oblong. The outer lip 

 seems to have been somewhat thickened. No folds at thé
