as Upper Silurian, but vseemed surprised at their being obtained 

 at the locality; and I promised to make a further examination of 

 the surrounding country when opportunity offered. This oppor- 

 tunity did not occur till twelve months had elapsed, I having 

 been away from the district in the meantime. 



My next visit enabled me to spend a little more time in the 

 locality, with the result that I feel certain this place will be 

 found to be of absorbing interest to future visitors, for it is here 

 that we have a section of country showing the Upper Silurian 

 and Middle Devonian rocks separated by a layer of contempo- 

 raneous tuffs and lavas, which occur in massive beds, and also of 

 a fragmentary nature. Further search at Glenbower anticline 

 revealed many more fossils of undoubted Upper Silurian age in 

 the shales and also the hard compact limestones, which contain 

 many corals, Crinoid- stems, brachiopods, and gastropods; but I 

 did not succeed in discovering any in the sandstones. 



Leaving the anticline, I followed the river bank down for some 

 distance, and found that a narrow strip of country, extending for 

 about a mile, consisted of shale with thin bands of limestone, the 

 whole mass being very highly contorted and covered here and 

 there with masses of the porphyritic tuff mentioned before as 

 capping the anticline. At about a mile below the anticline the 

 shale disappears, and is followed by an alluvial river flat, which 

 ends lower down the river at the foot of an imposing hill, known 

 locally as Clear Hill. 



As the shales seemed to me to be a continuation of the Glen- 

 bower formation, I examined them carefully for fossils, and was 

 rewarded by finding the following : — Stroinato'pora, Favosites 

 gothlandica, Heliolites^ Alveolites, Syringopora, Tryplasma, Am- 

 2)lexus, Pachypora (?), Cyathophyllum shear sbyi, Eth. fil. (1), 

 fasciculate Cyathophyllum, Spirifera, Atrypa reticularis, Linn., 

 Pentamerus (Barrandella) linguifer, Sby., var. tvilkinsoni, Eth. 

 fil., Pentamerus Knightii (?), Meristella, Loxonema compressa, 

 Munst., Orthoceras (at least two species), Crinoid stems, and the 

 trilobite Encrinurus barrandei, De Kon.
