The Harlech grits and Llanberis slates are referred to the BeviUian 

 system, the Lingula-flags to the Bevmian, and the Tremadoc slates 

 to the Salmian. G. A. L.

The writer is of opinion that the LaecJcenian figured in M. Eutot's 

 section is really Bnuvellian coloured and altered by infiltrations.

 Discusses the views of others on this subject, but thinks there is no 

 reason to alter Dumont's classification of the Revinian and Devillian 

 series in this district. The Mairu porphyry is regarded as non- 

 intrusive. G. A. L.

The crystalline rocks are mostly mica-schists with garnets, occa- 

 sionally approaching to gneiss ; connected with these are crystalline 

 limestones ; there is no proof that the latter are metamorphosed sedi- 

 mentary beds. The older eruptive rocks are Granites, Diorites, and 

 Syenites. Of Secondary rocks, limestones without fossils, but supposed 

 to be of Tithonic age, occur ; eruptive rocks connected therewith are 

 augite-porphyries and melaphyres. More than one subdivision of the 

 Miocene is seen, and a certain amount of lignite is found ; the eruptive 

 rocks connected with the Tertiaries are important, viz. hornblendic 

 andesites with and without quartz, augitic andesite, and basalt. The 

 andesites are mostly of Aquitanian age, being certainly older than the 

 Congeria-beds ; in the Nagyag district they all contain metallic veins. 

 The results of a microscopic examination of many of these rocks are 

 given. E. B. T.
