ON ESTUARINE DEPOSITS AT KIRMINGTON, LINCOLNSHIRE. 219 



Below the warp a few feet of sand is exposed in the brickyard, but 

 until our boring was put down there was no information as to the under- 

 lying bed. Our boring proved a thickness of 12 feet of sand and fine 

 chalky gravel, resting on 12 feet of stiff purple clay with foreign 

 stones, evidently a glacial clay, and then 11 feet of silt, sand, and fine 

 chalk rubble, below which it was impracticable to carry the boring 

 without tubing the hole, for which we had not the appliances. 



As boulder-clay is seen at one corner of the pit to overlie the fossili- 

 ferous warp, there seems no doubt that the bed lies between two glacial 

 deposits, but it is highly desirable that the section should be carried 

 downward to the chalk. 



The thanks of the Committee are due to Mr. J. Villiers of Beverley, 

 who very kindly put the boring down at his own cost ; also to the Earl of 

 Yarborough (landlord), Mr. Hervey (tenant), and Mr. E. P. Hankey (agent).

[Plates IV.-VIII.*] 



The scheme of work undertaken by the Committee includes the fol- 

 lowing : — 



(1) To record all fossils from the British Trias now deposited in 

 museums (public or private), special care being taken to get the exact 

 locality and horizon from which the fossils were obtained. 



(2) To compare the fossils from different horizons in order to see 

 whether any changes can be traced in the character of the fauna and 

 flora during Triassic times, and if geographical limits can be made out for 

 certain species. 



(3) To collect data regarding deep borings which show Triassic rocks. 



(4) To obtain photographs of slabs showing footprints or other fossils, 

 and of quarries and beds in which organic remains have been found. 



(5) To compile a bibliography of works and papers dealing with the 

 subject. 



Considerable progress has been made as the result of the Committee's 

 first year's work, and many offers of assistance have been received. The 

 Committee is especially indebted to Mr. H. C. Beasley, who has furnished 

 a report on cheirotheroid footprints, and has promised to write other 

 reports on rhyncosauroid and chelonoid footprints next year. 



REPORT ON FOOTPRINTS FROM THE TRIAS.— Part I. 



Introduction. 



The organic remains found in the Trias of Great Britain are so rare, 

 and confined to so few localities, that the animal life of the period might 

 appear to have been very limited, both in the number of species and of 

 individuals, but for the records of the presence of an abundant fauna pre-
