The present variety differs from the main species especially by its 

 irregularly arranged striæ. Otherwise it agrees well with the figure by Héri- 

 baud referred to above, but is somewhat smaller. It may perhaps be con- 

 sidered as only an abnormal specimen of the main species, which is a fos- 

 sil recorded from "Depot de Fraisse-Bas" (France).

Not before recorded from Arctic regions. Other record, Denmark. 



The present form is somewhat larger (18/^) than the Danish specimens 

 (14 /x) and — as far as I can see — is also somewhat more coarseh' striated 

 (16 striæ in 10 /j-., as compared with 20 in 10 /Jt); but as the striæ can be seen 

 only with great difficult^', they maj- after all be identical.
