Vft]6 caves are in cour.se of e.xainination, and the further exploration of 

 tlie Catacombs is in progress, there being reason to believe that the un- 

 explored portions considerably exceed those that have been examined.

The Secretary regrets that he has received no reports from members of 

 the Committee, and that the small sum of money voted last year, 51., has 

 not permitted work to be carried on on the usual scale. 



In the spring, a chart of the cliief fossil shells found at variou.s 

 horizons of the North Staffordshire coalfield was published by the Institute 

 of Mining and Mechanical Engineers. 



This chart was drawn up by Mr. J. T. Stobbs, F.G.S., and Dr. W. 

 Hind, F.G.S., and shows a section of the North Staffordshire coalfield, 

 with the marine beds at present known ; each bed in the section has 

 opposite to it the shells found in it, or a reference by a number to a shell 

 figured as being found in other beds. This chart is an amplification of a 

 section of North Staffordshire coalfields and on which the horizons at 

 which fossil shells occur, drawn up by Dr. W. Hind and published in his 

 monograph on CarhonicoJa, Anthraconiy'a, and Naiadites. The authors 

 contend that many of the important seams of the North Staffordshire coal- 

 field can be easily recognised by the mollusca found in connection with 

 them, and that the marine bands form absolutely certain indices of horizons. 



Collecting has been carried on by Mr. J. T. Stobbs, F.G.S., in Wensley- 

 dale and in Teesdale. 



The Secretary determined to examine the bed of Limestone mapped in 

 Quarter Sheet 102 S.E., which occurred intercalated in the Millstone Grit 

 beds. Mr. W. Gibson had called attention to this bed, thinking it possible 

 that the Pendleside fauna might be found there, but such is not the case. 



The carefully drawn up reports and sections by Mr. Stobbs speak for 

 themselves. The fossils are unfortunately not worth preserving, but the 

 Secretary has been able to identify the great majority, and his identifi- 

 cations are included in the lists in Mr. Stobbs's report. 



The district comprising Mickleton and Underthwaite Moors lies 

 between the River Lime and the River Balder (both of which are southern 

 tributaries of the River Tees), and is known as part of the area whence 

 the water-supply of Stockton and Middlesbrough is obtained. At the 

 present time thiee shafts and a tunnel are in progress of driving, the 

 positions of which are shown in fig. 1. The opportunity was taken of in- 

 specting the debi'is brought to the surface as a consequence of these works. 



The rocks occupying tliis area belong to the upper portion of the 

 Yoredale series, and consist mainly of finely laminated black shales. The 

 freestones are hard and approximate to the ' gannister ' type. The 

 sections afforded by the streams marked (A) were also examined (see 

 fig. 2). The whole series of beds points to a gradual termination of those
