TRANSACTIONS OF SECTION C. 601 



The Armagh district, ' 1,' sheet 47, afforded good and interesting collecting 

 grounds, though no fossils from the Silurian beds appear to have been previously 

 recorded. A close examination disclosed numerous localities in both upper and 

 lower strata, ranging from Lower Llandovery to Upper Llandeilo, this latter zone 

 being well represented a little north of Poyntzpass by the occurrence of — 



Dicellograptus moffateyisis. Cmnoyraptiis gracilis. 



„ sextans. Climacograptus scharenbergi, 



„ forchameri. Siphontreia miculce. 



Didymograptus superstes. 

 Dicranograptus ziczac. 

 Diplograptus bimucronatus. 



These forms were found in the black carbonaceous cherty band generally asso- 

 ciated with this particular horizon. 



* 1,' sheet 69, afforded substantial additions to the list already published there- 

 from. Graptolites were procured from some twelve additional localities, and 

 from many of these the specimens were obtained in excellent preservation ; in this 

 respect those from Killyrue, four miles S.E. of Cootehill, are specially worthy of 

 mention. 



The known localities for Silurian fossils on ' 1,' sheet 80, have been much 

 increased, and good specimens obtained of Lower Caradoc and Llandovery species. 

 Of the former Diplograptus foliaceus, Dicellograptus, and Pleurograptus were 

 indicated, whilst the higher zone is distinguished by such as Monograptus convolutus 

 and Monograptus tenuis, as also Diplograptus foliaceus or ^;«/??ieMS, which is some- 

 what rare outside Coalpit Bay district. 



The fossils of the Silurian rocks of 1,' sheet 81, are dealt with rather fully in 

 the memoirs of that and the adjoining sheet 91. In the latter the beautiful dis- 

 trict of Slane afforded a rich harvest of forms ranging from Llandeilo to Wenlock. 



Sheet 82 has been hitherto regarded as a barren area so far as fossils were con- 

 cerned. However, a close search disclosed at a couple of localities near Clogher 

 Head the existence of the zone of Monograptus exiguus on top of L'pper Llan- 

 dovery, and in addition to M. exiguus beautifully preserved specimens of Mono~ 

 graptus attemiatus, Crispxis,proteus and lobiferus were procured. At no other 

 locality save Tieveshilly was the same peculiar group observed. 



Having now reached the banks of the Boyne the north-eastern area may be 

 considered as ended. Not so the Silurian beds and their fossils, which proved 

 equally interesting and varied when traversed from the Boyne valley southwards 

 to the coast of Wexford and Waterford. 



9. Note on the Occurrence of Bag shot Beds at Comhe Pyne, near Lyme Regis.^ 

 By Horace B. Woodward, F.R.S. 



In the Summary of Progress of the Geological Survey for 1900, p. 122, Mr. 

 Clement Reid remarked, ' it is probable that a chain of outliers of the Bagshot 

 river-gravels -will connect the Eocene of Dorset with that of Bovey Tracey in 

 Devon.' 



The cuttings on the new railway between Axminstor and Lyme Regis have 

 since displayed, in the neighbourhood of Combe Pyne Hill, at an elevation of about 

 400 feet, beds of fine white sand, white pipe-clay, and white, red, and mottled 

 stony clays, with much rough flint and chert gravel. These beds have in places a 

 marked inclination towards the east, due probably to original deposition, and in all 

 respects they bear a close resemblance to the white and coloured clays and sands, 

 and the coarse gravels, which border the Bovey basin at Wolborough and other 

 places near Newton Abbot. They rest on a platform of Upper Greensand. 



_ The beds at Wolborough I some years ago regarded as equivalent to the ' plateau 

 drifts ' of Haldon, but Mr. Reid has recently brought forward evidence to show
