This species, identified by M'Coy (loc. cit.), has come under my notice, there 

 being examples of it in the Museum of Science and Art, Dublin (" Griffith 

 Collection"), and others in the general collection. It is a small species, 

 remarkable for the closeness and regularity of its septa. The siphuncle is 

 cylindrical and central, the test smooth. 



Locality. — Clane, county of Kildare. It is recorded from several places in 

 Ireland in Griffith's localities of Carboniferous fossils (M'Coy' s ' Synopsis,' 1862), 

 but I have not seen any specimens except from Kildare.

Up to the present time only one specimen of this species has been identified. 

 The characters can be satisfactorily made out, and I have no doubt as to the 

 accuracy of the reference. 



Locality. — St. Doulagh's, county of Dublin.
