LIX. — On some new or little-known Goniatites/ro/n the Car- 

 boniferous Limestone of Ireland. By G. C. Crick, F.G.S., 

 of the British Museum (Natural History). 



MOST of the specimens described in the present paper are in 

 the collection of Dr. A. H. Foord, F.G.S., of Dublin, who 

 has already devoted much attention to the Cephalopoda from 

 the Carboniferous Limestone of Ireland ; a few are in the 

 British Museum collection ; some belong to the Geoloo-ical 

 Survey of Ireland, and a iew to the Museum of Science and 

 Art, Dublin. To Dr. Foord, to the authorities of the Geolo- 

 gical Survey of Ireland and of the Museum of Science and 

 Art, Dublin, I am greatly indebted for the loan of the speci- 

 mens in their respective collections. 



During a visit to the Museum of the Geological Survey of 

 Ireland 1 was fortunate enough to identify the type speci- 

 mens of de Koninck's Goniatites [ = Pericyclus~] plicatilis and 

 G. [Brancoceras] ornatissimus. In order to facilitate com- 

 parison, I have redescribed them in the same manner as 

 the other species which are described in the present paper. 



The plan adopted for the descriptions of the species is that 

 given in the Introduction (pp. xviii and xix) to part iii. of the 

 ' Catalogue of Fossil Cephalopoda in the British Museum
