Irish Trilobitks. 
In Mr. F. R. Cowper Reed's paper {Q.J.G.S-, vol. Iviii., p. 74, 
1902) on- the genus lyichas, reference is made to the Lichas 
hibernicits of Portlock. From an examination of the type 
specimen the author considers that the head shields attributed 
by Portlock to this species, really belong to another distinct 
species, for which Mr. Reed proposes the new name Lichas 
kildarensis. 
Irish Carboniferous Cephalopoda. 
The concluding portion of Dr. Foord's important mono- 
graph>on the Carboniferous Cephalopoda of Ireland is now 
published (/*<:}'/. Soc.^ voL Ivii., 1903) and available for workers 
in palaeontology. In this final volume the families described 
belong to the Glyphioceratidse and Prolecantidae. In an 
appendix some additional species which have been examined 
since the earlier portions of the monograph were written are 
described, including a fine specimen of Teninocheilus coronatus. 
A useful synopsis of the families, genera, and species of 
Cephalopods is given at the end, and a glance through this 
reveals the fact that no less than forty-eight new species are 
described for the first time. Dr. Foord is to be heartily con- 
gratulated on the completion of this standard work of 
reference. 
Irish Minfrai^s. 
A supplementary list of minerals occurring in Ireland, 
additional to those mentioned at the British Association 
meeting at Belfast (Report, p. 598), is given by Mr. H. J. 
Seymour in the Report (p. 671) of the British Association 
Southport meeting, 1903. This list includes some species, 
many of which -were omitted from the previous list owing to 
lack of sufficiently authenticated records or otherwise. iThe
