AN EXPOSURE OF UPPER COAL MEASURES NEAR 

 CONISBOROUQH. 



H. CULPIN AND G. GRACE, B.Sc 



In the construction of the Dearne Valley Railway a recently- 

 made cutting near Conisboroug-h has exposed a series of clays 

 and sandstones underlying- the Permian. 



Among* them there occurs a thin band of soft ironstone 

 about 2 in. thick full of the impressions of a bivalve shell. 

 Prof. P. F. Kendall has submitted a specimen to Mr. H. A. 

 Allen, of the Geological Survey, and he identifies it as Anthra- 

 comya PhiUipsi. This has been confirmed by Dr. Wheelton 

 Hind, who reg-ards it as giving strong evidence that the beds 

 belong to the Upper Coal Measures. 



The discovery is interesting, as it is the first time Upper 

 Coal Measures have been found in Yorkshire. The only other 

 group of beds in the county reg-arded as belonging to them is 

 the Red Rock of Rotherham, from which, as yet, no fossils 

 sufficient for identification have been obtained. 



The work of examining the cutting in detail is in progress, 

 and it is hoped that sufficient evidence may be collected to place 

 the position of the beds beyond question. 



A notification of the discovery of Anihraconiya PhiUipsi has 

 been communicated to the Yorkshire Geological and Polytechnic 

 Society. 



HV/HENOPTERA. 



Mutilla europsea at Robin Hood's Bay. — On ist iVugust 

 last I found a female specimen of this rare ant running amongst 

 heather on the moors near Robin Hood's Bay. This makes the 

 second record of its occurrence in Yorkshire, where it is pro- 

 bably commoner than is supposed. A comparison of the 

 specimen with the figure and description given in Saunders' 

 ' Hymenoptera Aculeata of the British Isles,' leaves no doubt 

 whatever as to its identity. Its black head, red thorax, and 

 black abdomen with three silvery bands, one situated near the 

 thorax, the other two near the extremity of the insect and 

 broken in the centre, render it an unmistakable species. — Frank 

 Elgee, Middlesbrough, 31st December 1904.
