154 CARBONIFEBOUS CEPHALOPODA OF IRELAND. 



Remarks. — Since Mr. Crick described this fossil I have been enabled to expose 

 a portion of the suture-line (PI. XLVI, fig. 6 c). This shows that the species has 

 no relationship with Prolecanites, as assumed by its author, who had of course not 

 seen the suture-line when he wrote his description. The presence of ribbing (which 

 may with strong probability be admitted) and the general character of the suture- 

 line leaves little doubt that this species belongs to Pericyclus ; its relationship to 

 P. Glanensis, G. C. Crick, is pointed out under the description of that species. 



Locality. — Glenbane East, county of Limerick.
