PI. VIII. fig. 20. 



Shell s|iii'ally and obliquely conical, consisting of one whorl that 

 rapidly increases in thickness from the apex towards the aperture, the 

 detailed characters of which can not he directly seen. On the surface 

 can he observed one hroad and relatively strong longitudinal ridge, on 

 the outer side of the whorl, and faint indications of others on both side- 

 of the above. 



This form shows some likeness to several American as well as 

 European Devonian Platyceras-species, yet differs sufficiently to be re- 

 garded as an independent form. 



Occurrence: B, upper part, point north of the Beautiful Valley.

A small fragment, about 2 cm. long with a circular section and the 

 diameter increasing in the said distance from 8 to 12 mm. Surface 

 and interior unknown. 



Occurrence: B, lower part. Reindeer Valley.

Another fragment of about the same si/.e, but less conical in form, 

 showing the -mall -iphimcle lying a little eccentric. The section of the 

 -hell i- circular as lar a- can be seen from the incomplete specimen. 

 A -eptum of moderate convexity closes the lower end of the shell. A faint 

 line, a .-mall distance above this septum possibly indicates another, in 

 which case the distance between two septa would be 4 mm. while the 

 diameter nf the shell here i> 14 mm. Surface >niooth.
