4. On Ihe Presence of Goral-like Forms in the Grystalline Limestone of 

 Inishowen, Co. Bonegal. By Professor Edwaed Hull, LL.B., F.R.S. 



The existence of peculiar coral-like forms in the limestone of Culdaff in North 

 Donegal has long been known. The earliest notice of them is that by Mr. Patrick 

 Ganley in 1856, who states that they may 'rationally be regarded as organic 

 remains, and are probably referable to genera allied to such forms as Halygite^ 

 catenularis, Favosite^ Gothlandica, or Lithostrotion ' (' Joum. Geol. Soc. Dub.' vol. 

 Tii. p. 163). The late Professor W. King, of Galway, also regarded them as 

 fossils, and this view was held by the late Mr. W. H. Daily, Palaeontologist to the 

 Irish Geological Survey, who identified some of the specimens as belonging to tiie 

 genus HalysUeg. 



A large number of these forms had been collected during the progress of the 

 geological survey, and for the purpose of obtaining the views thereon of paleonto- 

 logists in various countries, photographs had been taken and distributed by the 

 author. Replies had now been received from several palaeontologists of acknow- 

 ledged authority, amongst whom may be mentioned Dr. Ferdinand Roemer of 

 Bresluu, Dr. Newberry, of the U.S. Geological Survey, Professor Dana, who 

 examined them in company with Mr. Charles E. Beecher, Professor James Hall, 

 author of the ' Palaeontology of New York,' all of whom pronounce the specimens 

 to be coralline. Dr. Newberry regards them as belonging to the American genus 

 Favistella, and kindly forwarded specimens of this fossil from the Trenton lime- 

 stone of America for comparison with those of (,'uldaft". In the opinion of the 

 author, and of his colleagues of the Irish Survey, the identity of some of them is 

 clear ; — due allowance being made for the amount of alteration to which the Culdaff 

 forms have been subjected. 



On the other hand, Dr. Selwyn, Dr. Alleyne Nicholson, Professor Haddon, and 

 some other British palaeontologists, give only a hesitating assent to the view of 

 their organic origin. 



The officers of the Irish Survey, including the author, after a close and pio- 

 longed examination and comparison, are fully persuaded that the forms are coral- 

 line. One specimen, at least, appears identical with a specimen of Favogitcx 

 fibrosm from the Lower Silurian beds of Co. Wexford, now in the collection of the 

 survey ; other forms apparently represent other species of (as Dr. Ferd. Roemer 

 considers) Favosites, or of Columnaria. Should the organic origin of these 

 fossils be established, as the author believed would be the case, the beds in wliich 

 they occur must be referred to the Lower Silurian system. 



Specimens and photographs were exhibited at the meeting.

6. Note on the recent Exposxires of K^'llavHiy's Rock at Bedford 

 By A. C. G. Camkron, F.G.S. 



Within the environs of Bedford, as well as higher up the valley, the basement 

 beds of the Oxford clay are extensively dug, and this has resulted in laying bare 

 an unsuspected development of Kellaway's Rock, the existence of which in Bed- 

 fordshire has not hitherto been recorded. The brick-fields and stone-pits adjoining
