ON THE LIFE ZONES IN THE BRITISH CARBONIFEROUS ROCKS. 297 



Several specimens of Dithyrocaris have been found, and a single speci- 

 men of a minute Trilobite, cf. Brachymetopus Ouralicus. Fish remains 

 referable to two genera have been identified. 



The fauna appears to bear little resemblance to that of the Cayton 

 Gill beds of Nidderdale, which lie at approximately the same horizon in 

 the Millstone Grit. 



On the whole, the fauna appears to resemble in many points that of 

 the Ridsdale Ironstone shell of the Bernician beds of South Northumber- 

 land. 



The Committee hope that the information obtained from this deposit 

 will be of value, in consideration of the comparative neglect with which 

 the fauna of the Millstone Grit has hitherto been treated. 



Owing to the temporary nature of the e.xposure the Committee con- 

 (sidered it advisable to expend a considerable portion of the grant in 

 obtaining the services of a competent collector, who has spent a fortnight 

 in making as exhaustive a collection as possible from the locality, under 

 the superintendence of Mr. Percy Kendall. The accounts have not yet 

 however, come in, and the Committee cannot therefore at present draw 

 upon the grant generously placed at their disposal by the Association, but 

 ask that the sum granted may be carried over to next year. They also 

 ask that a similar sum may be granted for that year. 



The Secretary has been in correspondence with the various members of 

 the Committee as to the best methods of forwarding the objects of the 

 Committee. From many of these he has received valuable suggestions, 

 and it is hoped that reports will be furnished at an early date from each 

 of the members for special districts, giving detailed sections of the rocks 

 in their individual areas, and stating what reliable information has 

 already been collected regarding their fossil contents, and what yet 

 remains to be done in this connection. 



Structure of a Coral Reef. — Report of the Committee, consisting of 

 Professor T. G. Bonney (Chairman), Professor W. J. Sollas 

 (Secretary), Sir Archibald Geikie, Professors J. W. Judd, 

 C. Lapworth, a. 0. Haddon, Boyd Dawkins, G. H. Darwin, 

 S. J. HicKSON, and A. Stewart, Admiral W. J. L. Wharton, 

 Drs. H. Hicks, J. Murray, W. T. Blanford, C. Le Neve Foster,

 Bourne, A. R. Binnie, J. W. Gregory, W. W. Watts, and 

 J. C. Hawkshaw, and Hon. P. Fawcett, appointed to consider a 

 project for investicjating a Coral Reef hn Boring and Sounding. 



As the expenses of the expedition were covered by the grants from funds 

 administered by the Royal Society, the sum of 40^., granted by the 

 Association at Liverpool, has not been drawn. But another expedition 

 has been already sent out from Sydney under the auspices of Professors 

 Anderson Stuart and Edgev/orth David and others, with machinery to 

 overcome the difficulties which wei'e fatal to the first attempt, and the 

 Committee ask that they may be reappointed, and that the grant made 

 last year, and not drawn, be renewed as a contribution to the expenses of 

 the new undertaking.
