with this subject, Mr. Ussher’s paper on the Recent Geology of 
Cornwall (Grou. Mac. 1879) may be studied with advantage. Dr. 
Barrois points out indications of glacial phenomena in Finistere, 
which he attributes to transport by floating ice. 
8. An article “On the Fauna of the Lower Carboniferous Limestones 
of Spergen Hill, Ind., with a revision of the descriptions of its fossils 
hitherto published, and illustrations of the species from the original 
type series” (Bulletin of the American Museum of Nat. Hist. vol. i. 
No. 3), by Mr. R. P. Whitfield, furnishes us with descriptions of 
Foraminifera, Echinodermata, Brachiopoda, Lamellibranchiata, Gas- 
teropoda, Heteropoda, Pteropoda, Cephalopoda, Annelida, and 
Ostracoda. 
9. Mr. G. H. Kinahan, in a paper entitled ‘‘ Paleozoic Rocks of 
Galway and elsewhere in Ireland, said to be Laurentians” (Scientific 
Proc. Roy. Dublin Soc. vol. ii.), discusses the evidence on which 
this classification has been based. He considers that the claim to 
the title of Laurentians for rocks in counties Donegal, Tyrone, and 
Mayo, has not been satisfactorily proven; on the contrary, the facts 
already put forward elsewhere, in favour of their being of Cambrian 
age, remain unanswered. In county Wexford, he points to the 
occurrence of Oldhamia as proving the Cambrian age of certain 
rocks, similar in character to others asserted to be older. Again, 
in West Galway, Mr. Kinahan points out that there is no conclusive 
evidence for identifying rocks of Laurentian age, observing that 
years ago Dr. Haughton classed the granitic rocks of Donegal and 
Galway together, and Dr. Hull also refers them to the same period 
of time. Mr. Kinahan remarks ‘that the Laurentianists pin their 
faith too much on lithological characters; while they nearly alto- 
gether neglect petrological or stratigraphical evidence ; and it would 
appear to me that if they go on as they have began, we shall have, 
before long, every metamorphic region, no matter what the age of 
its strata, dotted over with their Laurentian rocks.” H. B. W.

By Ciement Rep. : 
HE country described in the Memoir and Section above noted, is 
that embraced by Quarter-sheets 68 N.H. and 8.E. and a part 
of 68 N.W. of the Geological Survey Map. The chief interest of the 
district lies in the coast-section, which includes the finest exhibition 
of Glacial Drift in the country, and shows these beds in connexion 
with the so-called ‘Forest Bed” of Pre-Glacial or Pliocene Age: 
the inland sections (described by Mr. Reid and Mr. Woodward)
