Coal-measures. Attention is drawn to the association of the blattoid 

 remains with Cordaites leaves bearing the impressions of the tests 

 of Spirorbis pusillus. The suggestion is put forward that possibly 

 Carboniferous cockroaches were not only phytophagous in habit, 

 but frequented decaying Cordaites leaves in order to feed upon the 

 Spirorbis. 



The presence of Archimylacrid and Orthomylacrid forms, no less 

 than the presence of a species of Lamproptilia, is considered indicative 

 of a considerable advance in insect development in the British 

 Carboniferous beyond the more primitive palaeodictyopteran types ; 

 while their abundance in the Pennant and TJpper Series of the South 

 Wales Coal-field may justify the hope of finding more primitive forms 

 at a lower horizon in the same coal-field. Their occurrence may also 

 be indicative of the remains of a terrestrial fauna somewhere in the 

 South Wales Coal-measures. 



The President announced that at 7 p.m. on Wednesday, January 25, 

 1911, a Special General Meeting would be held, in order to consider 

 the following Resolutions of Council: — 



(a) That the space now occupied by the Museum be made available for the 



extension of the Library. 



(b) That it is desirable that the Society's collections of Fossils, Minerals, and 



Rocks, with certain exceptions to be subsequently specified, be offered 

 to one or more of the National Museums, provided that guarantees be 

 obtained that the specimens will be properly registered and rendered 

 available for scientific purposes. 



(c) That it is not desirable that the Society should accept money for any 



part of the collections, or in consideration of them. 



(d) That the Council be empowered to approach such Institution or Institutions 



with a view to carrying the above resolutions into effect, and that the 

 Council shall call another Special General Meeting to express approval 

 or otherwise of the arrangement proposed.

The following paper was read : — 



" The Carboniferous Rocks and Fossils in the Neighbourhood of 

 Pitscottie, Fifeshire." By R. M. Craig, M.A., B.Sc, Assistant 

 in the Geological Department, The University, St. Andrews, and 

 David Balsillie, Student of Science, The University, St. Andrews. 



The authors described a section of Carboniferous strata exposed in 

 Kininmonth Den, near Pitscottie, Fifeshire. These consist of sand- 

 stones, shales, and limestones, some of which are richly fossiliferous. 

 The most striking feature is the occurrence of well-marked bands 

 of limestone charged with true marine fossils, comprising corals, 

 brachiopods, polyzoa, and lamellibranchs, which elsewhere are 

 characteristic of the Lower Limestone group of the Carboniferous 

 Limestone Series. On physical and paloeontological grounds, the 

 authors suggest that the beds in this stream section ought to be 

 grouped with these lower limestones rather than with the Calciferous 

 Sandstone Series as mapped by the Geological Survey. The authors 

 showed a suite of fossils in illustration of the paper.
