Miocene" and Dumont's " Pliocene Diestien." It was recognised as 

 comprising two divisions or zones, the first characterised by Panopcea 

 menardi, and the second by Glycymeris \Pectunculus\ pilosa, both of 

 which are now included in the Anversian stage, or " Crag Noir," of 

 the Belgian Miocene, which are developed at Edeghem and Antwerp. 

 These two pelecypods occur in the Vindobonian strata of Europe, 

 P. menardi being found as well in the Lenham Beds, Box-Stones, and 

 Coralline Crag beds, whereas Glycymeris pilosa is found to frequent 

 the same horizons, being likewise a member of the St. Erth fauna. 

 Although acknowledging certain differences in the faunas of these 

 Upper Tertiary horizons, which may be probablv accounted for by 

 different conditions of environment, no great disparity of time need 

 be allowed for in considering their geological age. I am induced, 

 therefore, from a knowledge of their conchology, to regard the Coral- 

 line Crag,^ the St. Erth beds, and the Lenham Beds of Britain, together 

 with the Diestian and the Anversian of Belgium, as of Upper Mio- 

 cene age, and belonging to the stage Messinian or Mio-Pliocene, 

 while the Box-Stones, or Nodule beds of East Anglia, I should con- 

 sider as referable to the Vindobonian division of the Middle Miocene. 



(To be concluded). 



Limax tenellus in Shropshire. — In the Journal of Conchology for 1909 

 (vol. xii. , p. 285), I referred to the occurrence of Limax tenellus in the oak woods 

 of Wyre Forest, near Bewdley. The forest is situate on the confines of three 

 counties — Worcester, Shropshire and Stafford — to the first of which my former 

 record referred. In October, 1915, my friend Mr. J. Steele Elliott, with whom I 

 was staying at Dowles, and I found the slug in the oak woods near his house, both 

 in the parish of Arley, Staffordshire, and in the parish of Dowles, Shropshire. 

 The specimens we took were referable to the var. fulva. Limax tenellus was 

 found at Cheadle in North Staffordshire in 1909 by Mr. J. R. B. Masefield (antea 

 vol. xiii. , p. 42), but so far as I know it has not been taken hitherto in the south of 

 the county nor in Shropshire. — Chas. Oldham {Read before the Society, Dec. 8th,

I The Foraminiferal evidence, also, lends support to the view that the Coralline Crag is 

 of older age than has yet been accepted. According to the Monograph on the Crag Foramini- 

 fera by Jones, Burrows and others fPalaeontographical Society, 1S97, p. 369) the following species 

 are recorded from the Coralline Crag of Sudbourne : Nuinmulina J>lanulata, Aviphistegina 

 vulgaris, Operculina cotnplanata, and Orbiioides aspera, formerly determined as O. faujasi. 

 These are said to be " derived from earlier beds," although from a recent examination of the 

 specimens, which are in the Geological Department of the British Museum, they present the 

 appearance of having been found in situ. However, the so-called Nuinmulina might indicate 

 an Eocene or Oligocene horizon, but the other organisms are characteristically Miocene, espe- 

 cially when it may be stated th.it in Orbitoides aspera, after careful rubbing down of the 

 horizontal surface on the median plane of the figured example, there is exposed a series of minute 

 chamberlets of squarish or hexagonal outline which can only belong to the Miocene genus 

 Lepidocyclina.
