to geologists. Compiled by specialists in all its branches, it should 

 always be referred to by anyone engaged in work on the fossil forms. 

 The separate sections, Mammalia, Aves, Mollusca, etc., can be 

 separately obtained from tiie ZooU)gical Society at a reasonable price, 

 and as the contents of the papers are indexed into groups one can 

 easily find the forms upon which one is working. 



3. FoEAMiNiFERA. — Frederick Chapman describes numerous Fora- 

 niinifera from deep borings in the Mallee, about 6 miles east of the 

 South Australian boundaiy. He does not at present state the af;e, but 

 the forms appear to be of low Tertiary age. Other groups are described 

 and figured, and perhaps that of most interest is an Antedon, new, 

 but referred by comparison to a Port Jackson form. (Proc. Poy. Soc. 

 Victoria, xxvii, pt. i.) 



Heron- A Hen and Earland write on the Foraminifera in tlieir role 

 as world-buiklers ■, a review of the Forarainiferous limestones and 

 other rocks of the Eastern and Western Hemispheres (Journ. Quekett 

 Micro. Soc, xii). This is a general paper, but brings together a good 

 deal of information otherwise buried iu various publications. 



Rufus M. Bagg, on tlie Pliocene and Pleistocene Foraminifera from 

 Southern California (Dept. of Interior, U.S. Geol. Survey, Bull. 513, 

 92 pp. and 28 pis.), renders available a large number of forms for 

 comparison, all carefully worked out and illustrated. Very little is new, 

 but such monographs are of considerably more than local interest. 



4. Spongites saxonicus. — Dettmer (N"eues Jahrbuch, 1912 (2), 

 114-26) discusses the various forms known as Spongites saxonicus, 

 Geiuitz, from the Chalk. He compares them with Foraminifera, 

 worm-casts, and fucoid stems, and figures various specimens of each 

 kind, suggesting tliat these curious remains may have several origins. 

 Similar forms are fairh' abundant in our own Chalk, and readers 

 of the Geological Magazine will recall Dr. Bather's recent communi- 

 cation on worm-casts from the English Chalk (1911, pp. 481, 549) 

 preserved in the British Museum.'

The following communications were read — 



1. "The Ordovician and Silurian Rocks of the Lough Nafooey 

 Area (County Galwav)." By Charles Irving Gardiner, M.A., F.G.S., 

 and Sidney Hugh Reynolds, M.A., F.G.S., Professor of Geology iu 

 the University of Bristol. 



The Lough Nafooey area is a direct continuation of the Kilbride 

 area (described in 1912), from which it is separated by the Finny 

 lliver. It forms a ridge about 4 miles long, whicli reaches its 

 highest point (1,678 feet) at Curraghrevagh Mountain, and slopes 

 steeply down to Lough ISTafooey on the north, and more gradually to 

 Glen Trague on the south.
